Cloud Storage
via Deniable
Attribute
based
Encryption
IEEE-2015 Cloud storage services have become increasingly popular.
Because of the importance of privacy, many cloud storage
encryption schemes have been proposed to protect data from
those who do not have access. All such schemes assumed that
cloud storage providers are safe and cannot be hacked;
however, in practice, some authorities (i.e., coercers) may
force cloud storage providers to reveal user secrets or
confidential data on the cloud, thus altogether circumventing
storage encryption schemes. In this paper, we present our
design for a new cloud storage encryption scheme that
enables cloud storage providers to create convincing fake
user secrets to protect user privacy. Since coercers cannot
tell if obtained secrets are true or not, the cloud storage
providers ensure that user privacy is still securely protected.

Cost efficient
Multi cloud
Data Hosting
Scheme with
High
Availability
IEEE-2015 Nowadays, more and more enterprises and organizations are
hosting their data into the cloud, in order to reduce the IT
maintenance cost and enhance the data reliability. However,
facing the numerous cloud vendors as well as their
heterogenous pricing policies, customers may well be
perplexed with which cloud(s) are suitable for storing their
data and what hosting strategy is cheaper. The general status
quo is that customers usually put their data into a single
cloud (which is subject to the vendor lock-in risk) and then
simply trust to luck. Based on comprehensive analysis of
various state-of-the-art cloud vendors, this paper proposes a
novel data hosting scheme (named CHARM) which
integrates two key functions desired. The first is selecting
several suitable clouds and an appropriate redundancy
strategy to store data with minimized monetary cost and
guaranteed availability. The second is triggering a transition
process to re-distribute data according to the variations of
data access pattern and pricing of clouds. We evaluate the
performance of CHARM using both trace-driven
simulations and prototype experiments. The results show
that compared with the major existing schemes, CHARM
not only saves around 20% of monetary cost but also
exhibits sound adaptability to data and price adjustments.

3 JCCZ-03 Enabling Cloud Storage Auditing with Key Exposure Resistance
IEEE-2015 Cloud storage auditing is viewed as an important service to
verify the integrity of the data in public cloud. Current
auditing protocols are all based on the assumption that the
client’s secret key for auditing is absolutely secure. However,
such assumption may not always be held, due to the possibly
weak sense of security and/or low security settings at the
client. If such a secret key for auditing is exposed, most of
the current auditing protocols would inevitably become
unable to work. In this paper, we focus on this new aspect of
cloud storage auditing. We investigate how to reduce the
damage of the client’s key exposure in cloud storage
auditing, and give the first practical solution for this new
problem setting. We formalize the definition and the security
model of auditing protocol with key-exposure resilience and
propose such a protocol. In our design, we employ the binary
tree structure and the pre-order traversal technique to
update the secret keys for the client. We also develop a novel
authenticator construction to support the forward security
and the property of blockless verifiability. The security proof
and the performance analysis show that our proposed
protocol is secure and efficient.

4 JCCZ-04 MobiContext_
Cloud
IEEE-2015 In recent years, recommendation systems have seen
significant evolution in the field of knowledge engineering.
Most of the existing recommendation systems based their
models on collaborative filtering approaches that make them
simple to implement. However, performance of most of the
existing collaborative filtering based recommendation system
suffers due to the challenges, such as: (a) cold start, (b) data
sparseness, and (c) scalability. Moreover, recommendation
problem is often characterized by the presence of many
conflicting objectives or decision variables, such as users’
preferences and venue closeness. In this paper, we proposed
MobiContext, a hybrid cloud based Bi Objective
Recommendation Framework (BORF) for mobile social
networks. The MobiContext utilizes multi objective
optimization techniques to generate personalized
recommendations. To address the issues pertaining to cold
start and data sparseness, the BORF performs data
preprocessing by using the Hub Average (HA) inference
model. Moreover, the Weighted Sum Approach (WSA) is
implemented for scalar optimization and an evolutionary
algorithm (NSGAII) is applied for vector optimization to
provide optimal suggestions to the users about a venue.
5 JCCZ-05 OPoR
Enabling Proof
of
Retrievability
in Cloud
Computing
with Resource
Constrained
Devices
IEEE-2015 Cloud Computing moves the application software and
databases to the centralized large data centers, where the
management of the data and services may not be fully
trustworthy. In this work, we study the problem of ensuring
the integrity of data storage in Cloud Computing. To reduce
the computational cost at user side during the integrity
verification of their data, the notion of public verifiability
has been proposed. However, the challenge is that the
computational burden is too huge for the users with
resource-constrained devices to compute the public
authentication tags of file blocks. To tackle the challenge, we
propose OPoR, a new cloud storage scheme involving a cloud
storage server and a cloud audit server, where the latter is
assumed to be semi-honest. In particular, we consider the
task of allowing the cloud audit server, on behalf of the cloud
users, to pre-process the data before uploading to the cloud
storage server and later verifying the data integrity. OPoR
outsources the heavy computation of the tag generation to
the cloud audit server and eliminates the involvement of user
in the auditing and in the preprocessing phases.
Furthermore, we strengthen the Proof of Retrievabiliy (PoR)
model to support dynamic data operations, as well as ensure
security against reset attacks launched by the cloud storage
server in the upload phase.

6 JCCZ-06 Privacy-
Preserving
Public
Auditing for
IEEE-2015 To protect outsourced data in cloud storage against
corruptions, adding fault tolerance to cloud storage together
with data integrity checking and failure reparation becomes
critical. Recently, regenerating codes have gained popularity
due to their lower repair bandwidth while providing fault
tolerance. Existing remote checking methods for
regenerating-coded data only provide private auditing,
requiring data owners to always stay online and handle
auditing, as well as repairing, which is sometimes
impractical. In this paper, we propose a public auditing
scheme for the regenerating-code-based cloud storage. To
solve the regeneration problem of failed authenticators in the
absence of data owners, we introduce a proxy, which is
privileged to regenerate the authenticators, into the
traditional public auditing system model. Moreover, we
design a novel public verifiable authenticator, which is
generated by a couple of keys and can be regenerated using
partial keys. Thus, our scheme can completely release data
owners from online burden. In addition, we randomize the
encode coefficients with a pseudorandom function to
preserve data privacy. Extensive security analysis shows that
our scheme is provable secure under random oracle model
and experimental evaluation indicates that our scheme is
highly efficient .
7 JCCZ-07 Profit
Maximization
Scheme
IEEE-2015 As an effective and efficient way to provide computing
resources and services to customers on demand, cloud
computing has become more and more popular. From cloud
service providers’ perspective, profit is one of the most
important considerations, and it is mainly determined by the
configuration of a cloud service platform under given
market demand. However, a single long-term renting scheme
is usually adopted to configure a cloud platform, which
cannot guarantee the service quality but leads to serious
resource waste. In this paper, a double resource renting
scheme is designed firstly in which short-term renting and
long-term renting are combined aiming at the existing issues.
This double renting scheme can effectively guarantee the
quality of service of all requests and reduce the resource
waste greatly. Secondly, a service system is considered as an
M/M/m+D queuing model and the performance indicators
that affect the profit of our double renting scheme are
analyzed, e.g., the average charge, the ratio of requests that
need temporary servers, and so forth. Thirdly, a profit
maximization problem is formulated for the double renting
scheme and the optimized configuration of a cloud platform
is obtained by solving the profit maximization problem.

8 JCCZ-08 Reactive
Resource
Provisioning
Heuristics for
IEEE-2015 The need for low latency analysis over high-velocity data
streams motivates the need for distributed continuous
dataflow systems. Contemporary stream processing systems
use simple techniques to scale on elastic cloud resources to
handle variable data rates. However, application QoS is also
impacted by variability in resource performance exhibited
by clouds and hence necessitates ―dynamic dataflows‖ which
utilize alternate tasks as additional control over the
dataflow’s cost and QoS. Further, we formalize an
optimization problem to represent deployment and runtime
resource provisioning that allows us to balance the
application’s QoS, value, and the resource cost. We propose
two greedy heuristics, centralized and sharded, based on the
variable-sized bin packing algorithm and compare against a
Genetic Algorithm (GA) based heuristic that gives a near-
optimal solution. A large-scale simulation study, using the
Linear Road Benchmark and VM performance traces from
the AWS public cloud, shows that while GA-based heuristic
provides a better quality schedule, the greedy heuristics are
more practical, and can intelligently utilize cloud elasticity to
mitigate the effect of variability, both in input data rates and
cloud resource performance, to meet the QoS of fast data
applications.
9 JCCZ-09 SAE Toward
Efficient Cloud
Data Analysis
IEEE-2015 Social network analysis is used to extract features of human
communities and proves to be very instrumental in a variety
of scientific domains. The dataset of a social network is often
so large that a cloud data analysis service, in which the
computation is performed on a parallel platform in the
could, becomes a good choice for researchers not
experienced in parallel programming. In the cloud, a
primary challenge to efficient data analysis is the
computation and communication skew (i.e., load imbalance)
among computers caused by humanity’s group behavior
(e.g., bandwagon effect). Traditional load balancing
techniques either require significant effort to re-balance
loads on the nodes, or cannot well cope with stragglers. In
this paper, we propose a general straggler-aware execution
approach, SAE, to support the analysis service in the cloud.
It offers a novel computational decomposition method that
factors straggling feature extraction processes into more
fine-grained sub-processes, which are then distributed over
clusters of computers for parallel execution. Experimental
results show that SAE can speed up the analysis by up to
1.77 times compared with state-of-the-art solutions.

10 JCCZ-10 Service
Operatorawar
e Trust
Scheme for
Resource
IEEE-2015 This paper proposes a service operator-aware trust scheme
(SOTS) for resource matchmaking across multiple clouds.
Through analyzing the built-in relationship between the
users, the broker, and the service resources, this paper
proposes a middleware framework of trust management that
can effectively reduce user burden and improve system
dependability. Based on multi-dimensional resource service
operators, we model the problem of trust evaluation as a
process of multi-attribute decision-making, and develop an
adaptive trust evaluation approach based on information
entropy theory. This adaptive approach can overcome the
limitations of traditional trust schemes, whereby the trusted
operators are weighted manually or subjectively. As a result,
using SOTS, the broker can efficiently and accurately
prepare the most trusted resources in advance, and thus
provide more dependable resources to users. Our
experiments yield interesting and meaningful observations
that can facilitate the effective utilization of SOTS in a large-
scale multi-cloud environment.
11 JCCZ-11 Towards
Optimized
Fine Grained
Pricing of
IEEE-2015 Although many pricing schemes in IaaS platform are
already proposed with pay-as-you-go and subscription/spot
market policy to guarantee service level agreement, it is still
inevitable to suffer from wasteful payment because of
coarsegrained pricing scheme. In this paper, we investigate
an optimized fine-grained and fair pricing scheme. Two
tough issues are addressed: (1) the profits of resource
providers and customers often contradict mutually; (2) VM-
maintenance overhead like startup cost is often too huge to
be neglected. Not only can we derive an optimal price in the
acceptable price range that satisfies both customers and
providers simultaneously, but we also find a best-fit billing
cycle to maximize social welfare (i.e., the sum of the cost
reductions for all customers and the revenue gained by the
provider). We carefully evaluate the proposed optimized
fine-grained pricing scheme with two large-scale real-world
production traces (one from Grid Workload Archive and the
other from Google data center). We compare the new
scheme to classic coarse-grained hourly pricing scheme in
experiments and find that customers and providers can both
benefit from our new approach. The maximum social
welfare can be increased up to 72:98% and 48:15% with
respect to DAS-2 trace and Google trace respectively.

12 JCCZ-12 Understanding
the
Performance
and
IEEE-2015 Commercial clouds bring a great opportunity to the
scientific computing area. Scientific applications usually
require significant resources, however not all scientists have
access to sufficien high end computing systems. Cloud
computing has gained the attention of scientists as a
competitive resource to run HPC applications at a
potentially lower cost. But as DIfferent infrastructure, it is
unclear whether clouds are capable of running scientific
applications with a reasonable performance per money
spent. This work provides a comprehensive evaluation of
EC2 cloud in different aspects. We first analyze the
potentials of the cloud by evaluating the raw performance of
different services of AWS such as compute, memory,
network and I /O. Based on the findings on the raw
performance, we then evaluate the performance of the
scientific applications running in the cloud. Finally, we
compare the performance of AWS with a private cloud, in
order to find the root cause of its limitations while running
scientific applications. This paper aims to assess the ability of
the cloud to perform well, as well as to evaluate the cost of
the cloud in terms of both raw performance and scientific
applications performance Furthermore, we evaluate other
services including S3, EBS and DynamoDB among many
AWS services in order to assess the abilities of those to be
used by scientific applications and frameworks. We also
evaluate a real scientific compng application through the
Swift parallel scripting System at scale.
13 JDMZ-13 Anonymizing
Collections of
Tree Struct
Data- Data
Engg
IEEE-2015 Collections of real-world data usually have implicit or
explicit structural relations. For example, databases link
records through foreign keys, and XML documents express
associations between different values through syntax.
Privacy preservation, until now, has focused either on data
with a very simple structure, e.g. relational tables, or on data
with very complex structure e.g. social network graphs, but
has ignored intermediate cases, which are the most frequent
in practice. In this work, we focus on tree structured data.
Such data stem from various applications, even when the
structure is not directly reflected in the syntax, e.g. XML
documents. A characteristic case is a database where
information about a single person is scattered amongst
different tables that are associated through foreign keys. The
paper defines k(m;n)-anonymity, which provides protection
against identity disclosure and proposes a greedy
anonymization heuristic that is able to sanitize large
datasets. The algorithm and the quality of the anonymization
are evaluated experimentally.

14 JDMZ-14 FOCS Fast
Overlapped
Community
Search
IEEE-2015 However, most of the existing algorithms that detect
overlapping communities assume that the communities are
denser than their surrounding regions and falsely identify
overlaps as communities. Further, many of these algorithms
are computationally demanding and thus, do not scale
reasonably with varying network sizes. In this article, we
propose FOCS (Fast Overlapped Community Search), an
algorithm that accounts for local connectedness in order to
identify overlapped communities. FOCS is shown to be
linear in number of edges and nodes. It additionally gains in
speed via simultaneous selection of multiple near-best
communities rather than merely the best, at each iteration.
FOCS outperforms some popular overlapped community
finding algorithms in terms of
15 JDMZ-15 Making Digital
Artifacts_Data
Engg
IEEE-2015 The current Web has no general mechanisms to make digital
artifacts — such as datasets, code, texts, and images —
verifiable and permanent. For digital artifacts that are
supposed to be immutable, there is moreover no commonly
accepted method to enforce this immutability. These
shortcomings have a serious negative impact on the ability to
reproduce the results of processes that rely onWeb
resources, which in turn heavily impacts areas such as
science where reproducibility is important. To solve this
problem, we propose trusty URIs containing cryptographic
hash values. We show how trusty URIs can be used for the
verification of digital artifacts, in a manner that is
independent of the serialization format in the case of
structured data files such as nano publications.
16 JDMZ-16 Privacy Policy
Inference of
User-Uploaded
IEEE-2015 With the increasing volume of images users share through
social sites, maintaining privacy has become a major
problem, as demonstrated by a recent wave of publicized
incidents where users inadvertently shared personal
information. In light of these incidents, the need of tools to
help users control access to their shared content is apparent.
Toward addressing this need, we propose an Adaptive
Privacy Policy Prediction (A3P) system to help users
compose privacy settings for their images. We propose a
two-level framework which according to the user’s available
history on the site, determines the best available privacy
policy for the user’s images being uploaded. Our solution
relies on an image classification framework for image
categories which may be associated with similar policies, and
on a policy prediction algorithm to automatically generate a
policy for each newly uploaded image, also according to
users’ social features.

17 JDMZ-17 RRW - A
Robust and
Reversible
Watermarking
IEEE-2015 Advancement in information technology is playing an
increasing role in the use of information systems comprising
relational databases. These databases are used effectively in
collaborative environments for information extraction;
consequently, they are vulnerable to security threats
concerning ownership rights and data tampering.
Watermarking is advocated to enforce ownership rights over
shared relational data and for providing a means for
tackling data tampering. When ownership rights are
enforced using watermarking, the underlying data
undergoes certain modifications; as a result of which, the
data quality gets compromised. Reversible watermarking is
employed to ensure data quality along-with data recovery.
However, such techniques are usually not robust against
malicious attacks and do not provide any mechanism to
selectively watermark a particular attribute by taking into
account its role in knowledge discovery. Therefore,
reversible watermarking is required that ensures; (i)
watermark encoding and decoding by accounting for the role
of all the features in knowledge discovery; and, (ii) original
data recovery in the presence of active malicious attacks.
18 JDMZ-18 Sparsity
Learning
Formulations
for Mining
IEEE-2015 Traditional clustering and feature selection methods
consider the data matrix as static. However, the data
matrices evolve smoothly over time in many applications. A
simple approach to learn from these time-evolving data
matrices is to analyze them separately. Such strategy ignores
the time-dependent nature of the underlying data. In this
paper, we propose two formulations for evolutionary co-
clustering and feature selection based on the fused Lasso
regularization. The evolutionary co-clustering formulation is
able to identify smoothly varying hidden block structures
embedded into the matrices along the temporal dimension.
Our formulation is very flexible and allows for imposing
smoothness constraints over only one dimension of the data
matrices. The evolutionary feature selection formulation can
uncover shared features in clustering from time-evolving
data matrices. We show that the optimization problems
involved are non-convex, non-smooth and non-separable. To
compute the solutions efficiently, we develop a two-step
procedure that optimizes the objective function iteratively.
We evaluate the proposed formulations using the Allen
Developing Mouse Brain Atlas data. Results show that our
formulations consistently outperform prior methods.

Learning_Kno
wledge
Discovery
IEEE-2015 Social identity linkage across different social media
platforms is of critical importance to business intelligence by
gaining from social data a deeper understanding and more
accurate profiling of users. In this paper, we propose a
solution framework, HYDRA, which consists of three key
steps: (I) we model heterogeneous behavior by long-term
topical distribution analysis and multi-resolution temporal
behavior matching against high noise and information
missing, and the behavior similarity are described by multi-
dimensional similarity vector for each user pair; (II) we
build structure consistency models to maximize the structure
and behavior consistency on users’ core social structure
across different platforms, thus the task of identity linkage
can be performed on groups of users, which is beyond the
individual level linkage in previous study; and (III) we
propose a normalized-margin-based linkage function
formulation, and learn the linkage function by multi-
objective optimization where both supervised pair-wise
linkage function learning and structure consistency
maximization are conducted towards a unified Pareto
optimal solution. The model is able to deal with drastic
information missing, and avoid the curse-of-dimensionality
in handling high dimensional sparse representation.
20 JDMZ-20 Subgraph
Matching with
Set Similarity
IEEE-2015 In real-world graphs such as social networks, Semantic Web
and biological networks, each vertex usually contains rich
information, which can be modeled by a set of tokens or
elements. In this paper, we study a subgraph matching with
set similarity (SMS2) query over a large graph database,
which retrieves subgraphs that are structurally isomorphic
to the query graph, and meanwhile satisfy the condition of
vertex pair matching with the (dynamic) weighted set
similarity. To efficiently process the SMS2 query, this paper
designs a novel lattice-based index for data graph, and
lightweight signatures for both query vertices and data
vertices. Based on the index and signatures, we propose an
efficient two-phase pruning strategy including set similarity
pruning and structure-based pruning, which exploits the
unique features of both (dynamic) weighted set similarity
and graph topology. We also propose an efficient
dominating-set-based subgraph matching algorithm guided
by a dominating set selection algorithm to achieve better
query performance. Extensive experiments on both real and
synthetic datasets demonstrate that our method outperforms
state-of-the-art methods by an order of magnitude.

21 JDMZ-21 The Impact of
View Histories
on Edit
Recommendati
ons
IEEE-2015 Recommendation systems are intended to increase developer
productivity by recommending files to edit. These systems
mine association rules in software revision histories.
However, mining coarse grained rules using only edit
histories produces recommendations with low accuracy, and
can only produce recommendations after a developer edits a
file. In this work, we explore the use of finer grained
association rules, based on the insight that view histories
help characterize the contexts of files to edit. To leverage this
additional context and fine grained association rules, we
have developed MI, a recommendation system extending
ROSE, an existing edit based recommendation system. We
then conducted a comparative simulation of ROSE and MI
using the interaction histories stored in the Eclipse Bugzilla
system. The simulation demonstrates that MI predicts the
files to edit with significantly higher recommendation
accuracy than ROSE (about 63% over 35%), and makes
recommendations earlier, often before developers begin
editing. Our results clearly demonstrate the value of
considering both views and edits in systems to recommend
files to edit, and results in more accurate, earlier, and more
flexible recommendations.
22 JDMZ-22 Towards
Effective Bug
Triage with
Software Data
Reduction
Techniques
IEEE-2015 Software companies spend over 45 percent of cost in dealing
with software bugs. An inevitable step of fixing bugs is bug
triage, which aims to correctly assign a developer to a new
bug. To decrease the time cost in manual work, text
classification techniques are applied to conduct automatic
bug triage. In this paper, we address the problem of data
reduction for bug triage, i.e., how to reduce the scale and
improve the quality of bug data. We combine instance
selection with feature selection to simultaneously reduce data
scale on the bug dimension and the word dimension. To
determine the order of applying instance selection and
feature selection, we extract attributes from historical bug
data sets and build a predictive model for a new bug data set.
We empirically investigate the performance of data
reduction on totally 600,000 bug reports of two large open
source projects, namely Eclipse and Mozilla. The results
show that our data reduction can effectively reduce the data
scale and improve the accuracy of bug triage. Our work
provides an approach to leveraging techniques on data
processing to form reduced and high-quality bug data in
software development and maintenance.

Alignment
Hashing for
Efficient Image
IEEE-2015 Hashing is a popular and efficient method for nearest
neighbor search in large-scale data spaces, by embedding
high-dimensional feature descriptors into a similarity
preserving Hamming space with a low dimension. For most
hashing methods, the performance of retrieval heavily
depends on the choice of the high-dimensional feature
descriptor. Furthermore, a single type of feature cannot be
descriptive enough for different images when it is used for
hashing. Thus, how to combine multiple representations for
learning effective hashing functions is an imminent task. In
this paper, we present a novel unsupervised Multiview
Alignment Hashing (MAH) approach based on Regularized
Kernel Nonnegative Matrix Factorization (RKNMF),

Video
Promotion by
Cross-network
IEEE-2015 The emergence and rapid proliferation of various social
media networks have reshaped the way how video contents
are generated, distributed and consumed in traditional video
sharing portals. Nowadays, online videos can be accessed
from far beyond the internal mechanisms of the video
sharing portals, such as internal search and front page
highlight. Recent studies have found that external referrers,
such as external search engines and other social media
websites, arise to be the new and important portals to Lead
users to online videos. In this paper, we introduce a novel
cross-network collaborative application to help drive the
online traffic for given videos in traditional video portal
YouTube by leveraging the high propagation efficiency of
the popular Twitter followees.
25 JMCZ-01 Modelling and
Analysis_Mob
Comp
IEEE-2015 —In opportunistic networks, direct communication between
mobile devices is used to extend the set of services accessible
through cellular or WiFi networks. Mobility patterns and
their impact in such networks have been extensively studied.
In contrast, this has not been the case with communication
traffic patterns, where homogeneous traffic between all
nodes is usually assumed. This assumption is generally not
true, as node mobility and social characteristics can
significantly affect the end-to-end traffic demand between
them. To this end, in this paper we explore the joint effect of
traffic patterns and node mobility on the performance of
popular forwarding mechanisms, both analytically and
through simulations. Among the different insights stemming
from our analysis, we identify conditions under which
heterogeneity renders the added value of using extra relays
more/less useful. Furthermore, we confirm the intuition that
an increasing amount of heterogeneity closes the
performance gap between different forwarding policies,
making endto- end routing more challenging in some cases.

Information
Diffusion in
Mobile Social
IEEE-2015 The emerging of mobile social networks opens opportunities
for viral marketing. However, before fully utilizing mobile
social networks as a platform for viral marketing, many
challenges have to be addressed. In this paper, we address
the problem of identifying a small number of individuals
through whom the information can be diffused to the
network as soon as possible, referred to as the diffusion
minimization problem. Diffusion minimization under the
probabilistic diffusion model can be formulated as an
asymmetric k- center problem which is NP-hard, and the
best known approximation algorithm for the asymmetric k-
center problem has approximation ratio of log_ n and time

complexity of the approximation algorithm are not
satisfiable in large-scale mobile social networks.

IEEE-2015 Multimedia data with associated semantics is omnipresent in
today’s social online platforms in the form of keywords, user
comments, and so forth. This article presents a statistical
framework designed to infer knowledge in the imaging
domain from the semantic domain. Note that this is the
reverse direction of common computer vision applications.
The framework relates keywords to image characteristics
using a statistical significance test. It scales to millions of
images and hundreds of thousands of keywords. We
demonstrate the usefulness of the statistical framework with
three color imaging applications: 1) semantic image
enhancement: re-render an image in order to adapt it to its
semantic context; 2) color naming: find the color triplet for a
given color name; and 3) color palettes: find a palette of
colors that best represents a given arbitrary semantic
context and that satisfies established harmony constraints.

IEEE-2015 Data deduplication is a technique for eliminating duplicate
copies of data, and has been widely used in cloud storage to
reduce storage space and upload bandwidth. However, there
is only one copy for each file stored in cloud even if such a
file is owned by a huge number of users. As a result,
deduplication system improves storage utilization while
reducing reliability. Furthermore, the challenge of privacy
for sensitive data also arises when they are outsourced by
users to cloud. Aiming to address the above security
challenges, this paper makes the first attempt to formalize
the notion of distributed reliable deduplication system. We
propose new distributed deduplication systems with higher
reliability in which the data chunks are distributed across
multiple cloud servers.

IEEE-2015 This paper proposes a service operator-aware trust scheme
(SOTS) for resource matchmaking across multiple clouds.
Through analyzing the built-in relationship between the
users, the broker, and the service resources, this paper
proposes a middleware framework of trust management that
can effectively reduce user burden and improve system
dependability. Based on multi-dimensional resource service
operators, we model the problem of trust evaluation as a
process of multi-attribute decision-making, and develop an
adaptive trust evaluation approach based on information
entropy theory. This adaptive approach can overcome the
limitations of traditional trust schemes, whereby the trusted
operators are weighted manually or subjectively. As a result,
using SOTS, the broker can efficiently and accurately
prepare the most trusted resources in advance, and thus
provide more dependable resources to users. Our
experiments yield interesting and meaningful observations
that can facilitate the effective utilization of SOTS in a large-
scale multi-cloud environment.

Service
Brokering
Scheme
IEEE-2015 Oriented by requirement of trust management in multiple
cloud environment, this paper presents T-broker, a
trustaware service brokering scheme for efficient matching
cloud services (or resources) to satisfy various user requests.
First, a trusted third party-based service brokering
architecture is proposed for multiple cloud environment, in
which the T-broker acts as a middleware for cloud trust
management and service matching. Then, T-broker uses a
hybrid and adaptive trust model to compute the overall trust
degree of service resources, in which trust is defined as a
fusion evaluation result from adaptively combining the
direct monitored evidence with the social feedback of the
service resources. More importantly, T-broker uses the
maximizing deviation method to compute the direct
experience based on multiple key trusted attributes of
service resources, which can overcome the limitations of
traditional trust schemes, in which the trusted attributes are
weighted manually or subjectively. Finally, T-broker uses a
lightweight feedback mechanism, which can effectively
reduce networking risk and improve system efficiency. The
experimental results show that, compared with the existing
approaches, our T-broker yields very good results in many
typical cases, and the proposed system is robust to deal with
various numbers of dynamic service behavior from multiple
cloud sites.

IEEE-2015 Much research has been conducted to securely outsource
multiple parties’ data aggregation to an untrusted
aggregator without disclosing each individual’s privately
owned data, or to enable multiple parties to jointly aggregate
their data while preserving privacy. However, those works
either require secure pair-wise communication channels or
suffer from high complexity. In this paper, we consider how
an external aggregator or multiple parties can learn some
algebraic statistics (e.g., sum, product) over participants’
privately owned data while preserving the data privacy. We
assume all channels are subject to eavesdropping attacks,
and all the communications throughout the aggregation are
open to others. We first propose several protocols that
successfully guarantee data privacy under semi-honest
model, and then present advanced protocols which tolerate
up to k passive adversaries who do not try to tamper the
computation. Under this weak assumption, we limit both the
communication and computation complexity of each
participant to a small constant. At the end, we present
applications which solve several interesting problems via our
protocols.

IEEE-2015 Cloud computing is a revolutionary computing paradigm,
which enables flexible, on-demand, and low-cost usage of
computing resources, but the data is outsourced to some
cloud servers, and various privacy concerns emerge from it.
Various schemes based on the attribute-based encryption
have been proposed to secure the cloud storage. However,
most work focuses on the data contents privacy and the
access control, while less attention is paid to the privilege
control and the identity privacy. In this paper, we present a
semi anonymous privilege control scheme Anony Control to
address not only the data privacy, but also the user identity
privacy in existing access control schemes. Anony Control
decentralizes the central authority to limit the identity
leakage and thus achieves semi anonymity. Besides, it also
generalizes the file access control to the privilege control, by
which privileges of all operations on the cloud data can be
managed in a fine-grained manner. Subsequently, we present
the Anony Control-F, which fully prevents the identity
leakage and achieve the full anonymity. Our security
analysis shows that both Anony Control and Anony Control-
F are secure under the decisional bilinear Diffie–Hellman
assumption, and our performance evaluation exhibits the
feasibility of our schemes.

33 JSCZ-04 Data Lineage

IEEE-2015 Intentional or unintentional leakage of confidential data is
undoubtedly one of the most severe security threats that
organizations face in the digital era. The threat now extends
to our personal lives: a plethora of personal information is
available to social networks and smartphone providers and
is indirectly transferred to untrustworthy third party and
fourth party applications. In this work, we present a generic
data lineage framework LIME for data flow across multiple
entities that take two characteristic, principal roles (i.e.,
owner and consumer). We define the exact security
guarantees required by such a data lineage mechanism
toward identification of a guilty entity, and identify the
simplifying non-repudiation and honesty assumptions. We
then develop and analyze a novel accountable data transfer
protocol between two entities within a malicious
environment by building upon oblivious transfer, robust
watermarking, and signature primitives. Finally, we perform
an experimental evaluation to demonstrate the practicality of
our protocol and apply our framework to the important data
leakage scenarios of data outsourcing and social networks. In
general, we consider LIME , our lineage framework for data
transfer, to be an key step towards achieving accountability
by design.
34 JSCZ-05 Enabling
Cloud Storage
Auditing with
IEEE-2015 Cloud storage auditing is viewed as an important service to
verify the integrity of the data in public cloud. Current
auditing protocols are all based on the assumption that the
client’s secret key for auditing is absolutely secure. However,
such assumption may not always be held, due to the possibly
weak sense of security and/or low security settings at the
client. If such a secret key for auditing is exposed, most of
the current auditing protocols would inevitably become
unable to work. In this paper, we focus on this new aspect of
cloud storage auditing. We investigate how to reduce the
damage of the client’s key exposure in cloud storage
auditing, and give the first practical solution for this new
problem setting. We formalize the definition and the security
model of auditing protocol with key-exposure resilience and
propose such a protocol. In our design, we employ the binary
tree structure and the pre-order traversal technique to
update the secret keys for the client. We also develop a novel
authenticator construction to support the forward security
and the property of blockless verifiability. The security proof
and the performance analysis show that our proposed
protocol is secure and efficient.

IEEE-2015 Group behavior interactions, such as multirobot teamwork
and group communications in social networks, are widely
seen in both natural, social, and artificial behavior related
applications. Behavior interactions in a group are often
associated with varying coupling relationships, for instance,
conjunction or disjunction. Such coupling relationships
challenge existing behavior representation methods, because
they involve multiple behaviors from different actors,
constraints on the interactions, and behavior evolution. In
addition, the quality of behavior interactions are not checked
through verification techniques. In this paper, we propose an
ontology-based behavior modeling and checking system
(OntoB for short) to explicitly represent and verify complex
behavior relationships, aggregations, and constraints. The
OntoB system provides both a visual behavior model and an
abstract behavior tuple to capture behavioral elements, as
well as building blocks. It formalizes various intra-coupled
interactions (behaviors conducted by the same actor) via
transition systems (TSs), and inter-coupled behavior
aggregations (behaviors conducted by different actors) from
temporal, inferential, and party-based perspectives.

IEEE-2015 In this paper, we study a group key agreement problem
where a user is only aware of his neighbors while the
connectivity graph is arbitrary. In our problem, there is no
centralized initialization for users. A group key agreement
with these features is very suitable for social networks.
Under our setting, we construct two efficient protocols with
passive security. We obtain lower bounds on the round
complexity for this type of protocol, which demonstrates that
our constructions are round efficient. Finally, we construct
an actively secure protocol from a passively secure one.

Auditing for
IEEE-2015 To protect outsourced data in cloud storage against
corruptions, adding fault tolerance to cloud storage together
with data integrity checking and failure reparation becomes
critical. Recently, regenerating codes have gained popularity
due to their lower repair bandwidth while providing fault
tolerance. Existing remote checking methods for
regenerating-coded data only provide private auditing,
requiring data owners to always stay online and handle
auditing, as well as repairing, which is sometimes impractical.
In this paper, we propose a public auditing scheme for the
regenerating-code-based cloud storage. To solve the
regeneration problem of failed authenticators in the absence
of data owners, we introduce a proxy, which is privileged to
regenerate the authenticators, into the traditional public
auditing system model.

38 JSEZ-01 Impact of
view_DM
IEEE-2015 Recommendation systems are intended to increase developer
productivity by recommending files to edit. These systems
mine association rules in software revision histories.
However, mining coarse-grained rules using only edit
histories produces recommendations with low accuracy, and
can only produce recommendations after a developer edits a
file. In this work, we explore the use of fine-grained
association rules, based on the insight that view histories
help characterize the contexts of files to edit. To leverage this
additional context and fine-grained association rules, we
have developed MI, a recommendation system extending
ROSE, an existing edit based recommendation system. We
then conducted a comparative simulation of ROSE and MI
using the interaction histories stored in the Eclipse Bugzilla
system. The simulation demonstrates that MI predicts the
files to edit with significantly higher recommendation
accuracy than ROSE (about 63% over 35%), and makes
recommendations earlier, often before developers begin
editing. Our results clearly demonstrate the value of
considering both views and edits in systems to recommend
files to edit, and results in more accurate, earlier, and more
flexible recommendations.

IEEE-2015 This paper introduces a distributed fault-tolerant topology
control algorithm, called the Disjoint Path Vector (DPV), for
heterogeneous wireless sensor networks composed of a large
number of sensor nodes with limited energy and computing
capability and several supernodes with unlimited energy
resources. The DPV algorithm addresses the k-degree
Anycast Topology Control problem where the main objective
is to assign each sensor’s transmission range such that each
has at least k-vertex-disjoint paths to supernodes and the
total power consumption is minimum. The resulting
topologies are tolerant to k _ 1 node failures in the worst
case. We prove the correctness of our approach by showing
that topologies generated by DPV are guaranteed to satisfy
k-vertex supernode connectivity. Our simulations show that
the DPV algorithm achieves up to 4-fold reduction in total
transmission power required in the network and 2-fold
reduction in maximum transmission power required in a
node compared to existing solutions.

IEEE-2015 We propose a greedy algorithm, Cluster-MAX-COVERAGE
(CMC), to efficiently diagnose large-scale clustered failures.
We primarily address the challenge of determining faults
with incomplete symptoms. CMC makes novel use of both
positive and negative symptoms to output a hypothesis list
with a low number of false negatives and false positives
quickly. CMC requires reports from about half as many
nodes as other existing algorithms to determine failures with
100 percent accuracy. Moreover, CMC accomplishes this
gain significantly faster (sometimes by two orders of
magnitude) than an algorithm that matches its accuracy.
When there are fewer positive and negative symptoms at a
reporting node, CMC performs much better than existing
algorithms. We also propose an adaptive algorithm called
Adaptive-MAX-COVERAGE (AMC) that performs
efficiently during both independent and clustered failures.
During a series of failures that include both independent and
clustered, AMC results in a reduced number of false
negatives and false positives.

IEEE-2015 Network coding (NC) and multipacket reception with
successive interference cancelation (SIC) have been shown to
improve the performance of multihop wireless networks
(MWNs). However, previous work emphasized maximization
of network throughput without considering quality of service
(QoS) requirements, which may lead to high packet delays in
the network. The objective of this work is minimization of
packet delay in a TDMA-based MWN that is jointly utilizing
NC and SIC techniques for a given traffic demand matrix.
We assume conflictfree scheduling and allow multipath
routing. We formulate a cross-layer optimization that
assigns time slots to links in a way that the average packet
delay is minimized. The problem formulation results in a
difficult mixed integer nonlinear programming (MINLP)
that the state-of-art software can only solve for very small-
sized networks. For large networks, we develop a heuristic
approach that iteratively determines the optimal solution.
We present numerical results, which show that the average
packet delay and traffic handling capacity of a network,
using w/o NC+SIC, NC, SIC and NC+SIC schemes, improves
from left to right. The traffic capacity of NC+SIC is double
of the w/o NC+SIC. Thus, combined utilization of NC and
SIC techniques results in significant performance
improvement.

IEEE-2015 Although software-defined networking (SDN) brings
numerous benefits by decoupling the control plane from the
data plane, there is a contradictory relationship between
SDN and distributed denial-of-service (DDoS) attacks. On
one hand, the capabilities of SDN make it easy to detect and
to react to DDoS attacks. On the other hand, the separation
of the control plane from the data plane of SDN introduces
new attacks. Consequently, SDN itself may be a target of
DDoS attacks. In this paper, we first discuss the new trends
and characteristics of DDoS attacks in cloud computing
environments. We show that SDN brings us a new chance to
defeat DDoS attacks in cloud computing environments, and
we summarize good features of SDN in defeating DDoS
attacks. Then we review the studies about launching DDoS
attacks on SDN and the methods against DDoS attacks in
SDN.In addition, we discuss a number of challenges that
need to be addressed to mitigate DDoS attached in SDN with
cloud computing. This work can help understand how to
make full use of SDN’s advantages to defeat DDoS attacks in
cloud computing environments and how to prevent SDN
itself from becoming a victim of DDoSattacks.

IEEE-2015 This paper presents and experimentally demonstrates the

packet switching (OPS) network. Open flow control is
enabled by introducing The Openflow/OPS agent into the
OPS network, which realizes the Openflow protocol
translation and message exchange between the Openflow
control plane and the underlying OPS nodes. With software-
defined networking (SDN) and Openflow technique, the
complex control functions of the conventional OPS network
can offloaded into a centralized and flexible control plane,
while promoted control and operations can be provided due
to centralized coordination of network resources.
Furthermore, a contentionaware routing/rerouting strategy
as well as a fast network adjustment mechanism is proposed
and demonstrated for the first time as advanced Openflow
control to route traffic and handle the network dynamics.
With centralized SDN/Openflow control, the OPS network
has the potential to have better resource utilization and
enhanced network resilience at lower cost and less node
complexity. Our work will accelerate the development of
both OPS and SDN evolution.

IEEE-2015 In this paper, we propose a localization scheme named
Opportunistic Localization by Topology Control (OLTC),
specifically for sparse Underwater Sensor Networks
(UWSNs). In a UWSN, an unlocalized sensor node finds its
location by utilizing the spatio-temporal relation with the
reference nodes. Generally, UWSNs are sparsely deployed
because of the high implementation cost, and unfortunately,
the network topology experiences partitioning due to the
effect of passive node mobility. Consequently, most of the
underwater sensor nodes lack the required number of
reference nodes for localization in underwater environments.
The existing literature is deficient in addressing the problem
of node localization in the above mentioned scenario.
Antagonistically, however, we promote that even in such
sparse UWSN context, it is possible to localize the nodes by
exploiting their available opportunities.

IEEE-2015 Due to the broadcast nature of radio propagation, wireless
transmission can be readily overheard by unauthorized users
for interception purposes and is thus highly vulnerable to

emerging as a promising paradigm to protect the wireless
communications against eavesdropping attacks by exploiting
the physical characteristics of wireless channels. This article
is focused on the investigation of diversity techniques to
improve physical-layer security differently from the
conventional artificial noise generation and beamforming
techniques, which typically consume additional power for
generating artificial noise and exhibit high implementation
complexity for beamformer design. We present several
diversity approaches to improve wireless physical-layer
security, including multiple-input multiple-output (MIMO),
multiuser diversity, and cooperative diversity. To illustrate
the security improvement through diversity, we propose a

quality of service (QoS) in terms of delay. In order to meet
the delay requirement, it is important to consider topology
control in delay constrained environment, which is
contradictory to the objective of minimizing interference. In
this paper, we focus on the delay-constrained topology

IEEE-2015 In this paper, we consider lossy mobile ad hoc networks
where the data rate of a given flow becomes lower and lower
along its routing path. One of the main challenges in lossy
mobile ad hoc networks is how to achieve the conflicting goal
of increased network utility and reduced power
consumption, while without following the instantaneous state
of a fading channel. To address this problem, we propose a
cross-layer rate-effective network utility maximization
(RENUM) framework by taking into account the lossy
nature of wireless links and the constraints of rate outage
probability and average delay. In the proposed framework,
the utility is associated with the effective rate received at the
destination node of each flow instead of the injection rate at
the source of the flow. We then present a distributed joint
transmission rate, link power and average delay control
algorithm, in which explicit broadcast message passing is
required for power allocation algorithm.

IEEE-2015 In this paper, a joint optimization of link scheduling, routing
and replication for delay-tolerant networks (DTNs) has been
studied. The optimization problems for resource allocation
in DTNs are typically solved using dynamic programming
which requires knowledge of future events such as meeting
schedules and durations. This paper defines a new notion of
approximation to the optimality for DTNs, called snapshot
approximation where nodes are not clairvoyant, i.e., not
looking ahead into future events, and thus decisions are
made using only contemporarily available knowledges.
Unfortunately, the snapshot approximation still requires
solving an NP-hard problem of maximum weighted
independent set (MWIS) and a global knowledge of who
currently owns a copy and what their delivery probabilities
are. This paper proposes an algorithm, Max-Contribution

attacks. These attacks have pushed away potential business
firms and individuals whose aim is to get the best benefit in
e-commerce with minimal losses. The attacks occur during
interactions between the trading peers as a transaction takes
place. In this paper, we propose how to address Sybil attack,
an active attack, in which peers can have bogus and multiple
identities to fake their owns. Most existing work, which
concentrates on social networks and trusted certification, has
not been able to prevent Sybil attack peers from doing
transactions. Our work exploits the neighbor similarity trust
relationship to address Sybil attack. In our approach,
duplicated Sybil attack peers can be identified as the
neighbor peers become acquainted and hence more trusted
to each other. Security and performance analysis shows that
Sybil attack can be minimized by our proposed neighbor
similarity trust.

IEEE-2015 The LTE standards account for the use of relays to enhance

mobile can either establish a direct link to the base station
(BS) or a link to the relay, but not both. In this paper, we
consider the benefit of multipoint connectivity in allowing
user equipment (UEs) to split their transmit power over
simultaneous links to the BS and the relay, in effect
transmitting two parallel flows. We model decisions by the
UEs as to: (i) which point of access to attach to (either a relay
or a relay and the BS or only the BS); and (ii) how to allocate
transmit power over these links so as to maximize their total
rate. We show that this flexibility in the selection of points of
access leads to substantial network capacity increase against
when nodes operate in a fixed network topology. Individual
adaptations by UEs, in terms of both point of access and
transmit power, are interdependent due to interference and
to the possibility of over-loading of the backhaul links.

IEEE-2015 Statistics from security firms, research institutions and

instances have grown rapidly in recent years. Among various
data-leak cases, human mistakes are one of the main causes
of data loss. There exist solutions detecting inadvertent
sensitive data leaks caused by human mistakes and to
provide alerts for organizations. A common approach is to
screen content in storage and transmission for exposed
sensitive information. Such an approach usually requires the
detection operation to be conducted in secrecy. However, this
secrecy requirement is challenging to satisfy in practice, as
detection servers may be compromised or outsourced. In this
paper, we present a privacypreserving data-leak detection
(DLD) solution to solve the issue where a special set of
sensitive data digests is used in detection. The advantage of
our method is that it enables the data owner to safely
delegate the detection operation to a semihonest provider
without revealing the sensitive data to the provider. We
describe how Internet service providers can offer their
customers DLD as an add-on service with strong privacy
guarantees. The evaluation results show that our method can
support accurate detection with very small number of false
alarms under various data-leak scenarios.

which employs the alternate jamming and secrecy-enhanced
relay selection to prevent the confidential message from

dense deployments of femtocells however, pose several
unique challenges relating to interference and resource
management in OFDMA femtocell networks. Towards
addressing these challenges, we propose RADION, a
distributed resource management framework that effectively
manages interference across femtocells. RADION’s core
building blocks enable femtocells to opportunistically
determine the available resources in a completely distributed
and efficient manner. Further, RADION’s modular nature
paves the way for different resource management solutions
to be incorporated in the framework. We implement
RADION on a real WiMAX femtocell testbed deployed in a
typical indoor setting. Two distributed solutions are enabled
through RADION and their performance is studied to
highlight their quick self-organization into efficient resource

catastrophic complexity, information dissemination appears
an effective way in machine swarm. To fully understand
practical data transportation, G/G/1 queuing network model

IEEE-2015 The dominate spectrum sharing paradigm of today is
interference avoidance, where a secondary network can use
the spectrum only when such a use is not interfering with the
primary network. However, with the advances of physical-
layer technologies, the mindset of this paradigm is being
challenged. This paper explores a new paradigm called
―transparent coexistence‖ for spectrum sharing between
primary and secondary nodes in a multihop network
environment. Under this paradigm, the secondary network is
allowed to use the same spectrum simultaneously with the
primary network as long as their activities are ―transparent‖
(or ―invisible‖) to the primary network. Such transparency
is accomplished through a systematic interference
cancelation (IC) by the secondary nodes without any impact
on the primary network. Although such a paradigm has been
studied in the information theory (IT) and communications
(COMM) communities, it is not well understood in the
wireless networking community, particularly for multihop

Control Model for Energy Saving
IEEE-2015
Increasing attention is being paid to energy efficiency in subway systems to reduce operational cost and carbon emissions. Optimization of the driving strategy and efficient utilization of regenerative energy are two effective methods to reduce the energy consumption for electric subway systems. Based on a common scenario that an accelerating train can reuse the regenerative energy from a braking train on the opposite track, this paper proposes a cooperative train control model to minimize the practical energy consumption, i.e., the difference between traction energy and the reused regenerative energy. First, we design a numerical algorithm to calculate the optimal driving strategy with the given trip time, in which the variable traction force, braking force, speed limits, and gradients are considered.

Starting from the raw data, the implemented orientation filter provides the correct orientation of the subject in terms of Yaw, Pitch and Roll angles. The system is tested according to experimental protocols, engaging volunteers who performed simulated falls, simulated falls with recovery and Activities of Daily Living (ADL). By placing our wearable sensor on the waist of the subject, the unit is able to achieve fall detection performance above those of similar systems proposed in literature.

IEEE-2015 Measurements of sun-induced chlorophyll fluorescence (SIF) over plant canopies provide a proxy for plant photosynthetic capacity and are of high interest for plant research. Together with spectral reflectance, SIF has the potential to act as a non-invasive approach to quantify photosynthetic plant traits from field to air- and spaceborne scales. But SIF is a small signal contribution to the reflected sunlight and often not distinguishable from sensor noise. SIF estimation is, therefore, affected by an unquantified uncertainty, making it difficult to estimate accurately how much SIF is truly emitted from the plant. To investigate and overcome this, we designed a device based on a spectrometer covering the visible range and equipped it with an LED emitting at the wavelength of SIF. Using this as a reference and applying thorough calibrations, we present consistent evidence of the instrument’s capability of SIF retrieval and accuracy estimations. The LED’s intensity was measured under sunlight with 1.27 ± 0.27 mW×sr-1m-2nm-1 stable over the day. The large increase of SIF due to the
33
Kautsky effect was measured spectrally and temporally proving the biophysical origin of the signal. We propose rigorous tests for instruments intended to measure SIF and show ways to further improve the presented methods.
59 EST-04 A Runtime Integrity Monitoring Framework for Real-Time Relative Positioning Systems Based on GPS and DSRC
IEEE-2015 This paper provides a three-layered framework to monitor the positioning performance requirements of real-time relative positioning (RRP) systems of the Cooperative Intelligent Transport Systems that support cooperative collision warning (CCW) applications. These applications exploit state data of surrounding vehicles obtained solely from the Global Positioning System (GPS) and dedicated short-range communications (DSRC) units without using other sensors. To this end, this paper argues the need for the GPS/DSRC-based RRP systems to have an autonomous monitoring mechanism, since the operation of CCW applications is meant to augment safety on roads. The advantages of autonomous integrity monitoring are essential and integral to any safety-of-life system. The autonomous integrity monitoring framework proposed necessitates the RRP systems to detect/predict the unavailability of their subsystems and of the integrity monitoring module itself and, if available, to account for effects of data link delays and breakages of DSRC links, as well as of faulty measurement sources of GPS and/or integrated augmentation positioning systems, before the information used for safety warnings/alarms becomes unavailable, unreliable, inaccurate, or misleading.
60 EST-05 A Self-Sustainable Power Management System for Reliable Power Scaling Up of Sediment Microbial Fuel Cells
IEEE-2015 Sediment microbial fuel cells (SMFCs) are considered a promising renewable power source for remote monitoring Applications. However, existing SMFCs can only produce several mill watts of power, and the output power is not scaled linearly with the size of SMFCs. An effective alternative method to increase the output power is to independently operate multiple SMFCs, each of which has an optimal size for maximum power density. Independently operated SMFCs have electrically isolated electrodes (anodes/cathodes), which complicates the design of a suitable power management system (PMS). This paper describes the challenges in designing a PMS that can harvest energy from multiple independently operated (mio) SMFCs and accordingly proposes a design solution. From experimental results, the proposed PMS demonstrates reliable output power scaling up of mio-SMFC. The proposed PMS is self-sustainable because it is powered entirely from harvested energy without requiring additional external power sources.

61 EST-06 A Single- Stage Photovoltaic System for a Dual-Inverter-Fed Open- End Winding Induction Motor Drive for Pumping Applications
IEEE-2015 This paper presents an integrated solution for a photovoltaic (PV)-fed water-pump drive system, which uses an openend winding induction motor (OEWIM). The dual-inverter-fed OEWIM drive achieves the functionality of a three-level inverter and requires low value dc-bus voltage. This helps in an optimal arrangement of PV modules, which could avoid large strings and Helps in improving the PV performance with wide bandwidth of operating voltage. It also reduces the voltage rating of the dc-link capacitors and switching devices used in the system. The proposed control strategy achieves an integration of both maximum power point tracking and V/f control for the efficient utilization of the PV panels and the motor. The proposed control scheme requires the sensing of PV voltage and current only. Thus, the system requires less number of sensors. All the analytical, simulation, and experimental results of this work under different environmental conditions are presented in this paper.
62 EST-07 A Smart Sensor Network for Sea Water Quality Monitoring
IEEE-2015 Measurement of chlorophyll concentration is gaining more-and-more importance in evaluating the status of the marine ecosystem. For wide areas monitoring a reliable architecture of wireless sensors network is required. In this paper, we present a network of smart sensors, based on ISO/IEC/IEEE 21451 suite of standards, for in situ and in continuous space– time monitoring of surface water bodies, in particular for seawater. The system is meant to be an important tool for evaluating water quality and a valid support to strategic decisions concerning critical environment issues. The aim of the proposed system is to capture possible extreme events and collect long-term periods of data.
63 EST-08 A Train Localization Algorithm for Train Protection Systems of the Future
IEEE-2015 This paper describes an algorithm that enables a railway vehicle to determine its position in a track network. The system is based solely on onboard sensors such as a velocity sensor and a Global Navigation Satellite System (GNSS) sensor and does not require trackside infrastructure such as axle counters or balises. The paper derives a probabilistic modeling of the localization task and develops a sensor fusion approach to fuse the inputs of the GNSS sensor and the velocity sensor with the digital track map. We describe how we can treat ambiguities and stochastic uncertainty adequately. Moreover, we introduce the concept of virtual balises that can be used to replace balises on the track and evaluate the approach experimentally. This paper focuses on an accurate modeling of sensor and estimation uncertainties, which is relevant for safety critical applications.

64 EST-09 Alleviation of Electromagnetic Interference Noise Using a Resonant Shunt for Balanced Converters
IEEE-2015 Balanced converter is an effective way to reduce the CM noise. However, the parasitic capacitance between the switch and heat sink leads to resonant problems, resulting in high noise in certain frequency range. This paper proposes a novel coupled inductor structure based on the balanced technique for the Boost converter to further reduce the CM noise at certain frequency range. A shunt resonant path is adopted to offer a maximum suppression. The analytical estimation for shunt winding’s performance is provided for better design. Some simulation and experimental results of this new technique are presented to validate its effectiveness. The experiments about the capacitance unbalance, different load current, and reduction of the CM inductor size are also discussed for better understanding of this technique.
65 EST-10 An Approach of Reliable Data Transmission With Random Redundancy for Wireless Sensors in Structural Health Monitoring
IEEE-2015 Lossy transmission is a common problem suffered from monitoring systems based on wireless sensors. Though extensive works have been done to enhance the reliability of data communication in computer networks, few of the existing methods are well tailored for the wireless sensors for structural health monitoring (SHM). These methods are generally unsuitable for resource-limited wireless sensor nodes and intensive data SHM applications. In this paper, a new data coding and transmission method is proposed that is specifically targeted at the wireless SHM systems deployed on large civil infrastructures. The proposed method includes two coding stages: 1) a source coding stage to compress the natural redundant information inherent in SHM signals and 2) a redundant coding stage to inject artificial redundancy into wireless transmission to enhance the transmission reliability. Methods with light memory and computational overheads are adopted in the coding process to meet the resource constraints of wireless sensor nodes. In particular, the lossless entropy compression method is implemented for datacompression, and a simple random matrix projection is proposed for redundant transformation. After coding, a wireless sensor node transmits the same payload of coded data instead of the original sensor data to the base station. Some data loss may occur during the transmission of the coded data. However, the complete original data can be reconstructed losslessly on the base station from the incomplete coded data given that the data loss ratio is reasonably low. The proposed method is implemented into the Imote2 smart sensor platform and tested in a series of communication experiments on a cable-stayed bridge.

66 EST-11 Automated Health Alerts Using In-Home Sensor Data for Embedded Health Assessment
IEEE-2015 We present an example of unobtrusive, continuous monitoring in the home for the purpose of assessing early health changes. Sensors embedded in the environment capture behavior and activity patterns. Changes in patterns are detected as potential signs of changing health. We _rst present results of a preliminary study investigating 22 features extracted from in-home sensor data. A 1-D alert algorithm was then implemented to generate health alerts to clinicians in a senior housing facility. Clinicians analyze each alert and provide a rating on the clinical relevance. These ratings are then used as ground truth for training and testing classi_ers. Here, we present the methodology for four classi_cation approaches that fuse multisensory data. Results are shown using embedded sensor data and health alert ratings collected on 21 seniors over nine months. The best results show similar performance for two techniques, where one approach uses only domain knowledge and the second uses supervised learning for training. Finally, we propose a health change detection model based on these results and clinical expertise. The system of in-home sensors and algorithms for automated health alerts provides a method for detecting health problems very early so that early treatment is possible. This method of passive in-home sensing alleviates compliance issues.
67 EST-12 Compact Personal Distributed Wearable Exposimeter
IEEE-2015 A compact wearable Personal Distributed Exposimeter is proposed, sensing the power density of incident radio-frequency (RF) fields on the body of a human. In contrast to current commercial exposimeters, our Personal Distributed Exposimeter, being composed of multiple compact personal wearable RF exposimeter sensor modules, minimizes uncertainties caused by the proximity of the body, the specific antenna used and the exact position of the exposimeter. For unobtrusive deployment inside a jacket, each individual exposimeter sensor module is specifically implemented on the feedplane of a textile patch antenna. The new wearable sensor module’s high-resolution logarithmic detector logs RF signal levels. Next, on-board flash memory records minimum, maximum and average exposure data over a time span of more than two weeks, at a one-second sample period. Sample-level synchronization of each individual exposimeter sensor module enables combining of measurements collected by different nodes. The system is first calibrated in an anechoic chamber, and then compared to a commercially available single-unit exposimeter.

68 EST-13 Intra-Vehicle Networks: A Review
IEEE-2015 Automotive electronics is a rapidly expanding area With an increasing number of safety, driver assistance, and infotainment devices becoming standard in new vehicles. Current vehicles generally employ a number of different networking protocols to integrate these systems into the vehicle. The introduction of large numbers of sensors to provide driver assistance applications and the associated high-bandwidth requirements of these sensors have accelerated the demand for faster and more flexible network communication technologies within the vehicle.

69 EST-14 Multirobot Control Using Time-Varying Density Functions
IEEE-2015 An approach is presented for influencing teams of robots by means of time-varying density functions, representing rough references for where the robots should be located. A continuous-time coverage algorithm is proposed and distributed approximations are given whereby the robots only need to access information from adjacent robots. Robotic experiments show that the proposed algorithms work in practice, as well as in theory.
70 EST-15 Optimization-Based Motion Planning in Joint Space for Walking Assistance With Wearable Robot
IEEE-2015 In this paper, we propose an alternative motion planning method for a wearable robot with a variable stride length and walking speed. Trajectories are planned in a joint space rather than a workspace to avoid an ill-posed problem with no solution in inverse kinematics, and to consider the joint’s range of motion, maximum velocity, foot clearance, and backward balance. The joint trajectories are represented by minimum jerk trajectories. Two via-points are assigned, and the parameters (angle and angular velocity) at the via-points are determined by applying an inverted pendulum model or optimization to satisfy the constraints. The fastest gait pattern generated by the proposed algorithm was twice as fast as the pattern generated by the workspace-based planning method. We confirmed that the fastest walking pattern of 0.36 m/s was feasible on a tread mill, and a walking pattern of 0.27 m/s was found for walking across the floor with a walker. Furthermore, the proposed method required approximately 65% of the electric power for the workspace-based method for the same walking speed and stride length. These results suggest that the proposed motion planning method is effective at generating a high-speed and efficient gait pattern for a wearable robot.

Transverse feedback linearization makes the desired path attractive and invariant, while the dynamic extension allows the closed-loop system to achieve the desired motion along the path.

73 EST-18 Road Edge Recognition Using the Stripe Hough Transform From Millimeter-Wave Radar Images
IEEE-2015 Millimeter-wave (MMW) radar, which is used for road feature recognition, has performance that is superior to optical cameras in terms of robustness in different weather and lighting conditions, as well as providing ranging capabilities. However, the signatures of road features in MMW radar images are different from that of optical images, and even physically continuous features, such as road edges, will be presented as a set of bright points or spots distributed along the roadside. Therefore, discrimination of the radar features is of paramount importance in automotive imaging systems. To tackle this problem, an approach called the stripe Hough transform (HT) is introduced in this paper, allowing enhanced extraction of the geometry of the road path. The performance of the approach is demonstrated by comparison of extracted features from MMW images with the real geometry of the road and with the results of processing by classical HT.

Finally, a representational state transfer application allows us to test the interoperability and visualize energy savings in an office room.
76 EST-21 Wearable Sensors for Human Activity Monitoring: A Review
IEEE-2015 An increase in world population along with a significant aging portion is forcing rapid rises in healthcare costs. The healthcare system is going through a transformation in which continuous monitoring of inhabitants is possible even without hospitalization. The advancement of sensing technologies, embedded systems, wireless communication technologies, nano technologies, and miniaturization makes it possible to develop smart systems to monitor activities of human beings continuously. Wearable sensors detect abnormal and/or unforeseen situations by monitoring physiological parameters along with other symptoms. Therefore, necessary help can be provided in times of dire need. This paper reviews the latest reported systems on activity monitoring of humans based on wearable sensors and issues to be addressed to tackle the challenges.
77 EST-22 Design of a Mobile Charging Service for Electric Vehicles in an Urban Environment
IEEE-2015 This paper presents a novel approach to providing a service for electric-vehicle (EV) battery charge replenishment. This is an alternate system in which the charge replenishment is provided by mobile chargers (MCs). These chargers could have two possible configurations: a mobile plug-in charger (MP) or a mobile battery-swapping station (MS). A queuing-based
40
analytical approach is used to determine the appropriate range of design parameters for such a mobile charging system. An analytical analysis is first developed for an idealized system with a nearest-job-next (NJN) service strategy explored for such a system. In a NJN service strategy, the MC services the next spatially closest EV when it is finished with its current request. An urban environment approximated by Singapore is then analyzed through simulation. Charging requests are simulated through a trip generation model based on Singapore. In such a realistic environment, an updated practical NJN service strategy is proposed. For an MP system in an urban environment such as Singapore, there exists an optimal battery capacity with a threshold battery charge rate. Similarly, the battery swap capacity of an MS system does not need to be large for the system to perform.
78 EST-23 Comparison of Charge Estimation Methods in Partial Discharge Cable Measurements
IEEE-2015 The aim of this paper is to compare different partial discharge (PD) charge estimation methods for PD cable measurements. The paper covers the mathematical foundation behind the different presented methods, and explores the limits of each method regarding the associated maximum charge estimation errors in PD cable measurements. The results are focused on long cables where large PD pulse distortions are present and therefore, the measured pulses differ significantly from the calibrator ones. Each proposed method is analyzed, and finally, limitations of each method are discussed.
79 EST-24 Hierarchical and Networked Vehicle Surveillance in ITS: A Survey
IEEE-2015 Traffic surveillance has become an important topic in intelligent transportation systems (ITSs), which is aimed at monitoring and managing traffic flow. With the progress in computer vision, video-based surveillance systems have made great advances on traffic surveillance in ITSs. However, the performance of most existing surveillance systems is susceptible to challenging complex traffic scenes (e.g., object occlusion, pose variation, and cluttered background). Moreover, existing related research is mainly on a single video sensor node, which is incapable of addressing the surveillance of traffic road networks. Accordingly, we present a review of the literature on the video-based vehicle surveillance systems in ITSs.We analyze the existing challenges in video-based surveillance systems for the vehicle and present a general architecture for video surveillance systems, i.e., the hierarchical and networked vehicle surveillance, to survey the different existing and potential techniques.

80 MIPST-01 Bayesian Fusion of Multi-Band Images
IEEE-2015 This paper presents a Bayesian fusion technique for remotely sensed multi-band images is presented. The observed images are related to the high spectral and high spatial resolution image to be recovered through physical degradations, e.g., spatial and spectral blurring and/or subsampling defined by the sensor characteristics. The fusion problem is formulated within a Bayesian estimation framework. An appropriate prior distribution exploiting geometrical consideration is introduced. To compute the Bayesian estimator of the scene of interest from its posterior distribution, a Markov chain Monte Carlo algorithm is designed to generate samples asymptotically distributed according to the target distribution. To efficiently sample from this high-dimension distribution, a Hamiltonian Monte Carlo step is introduced in the Gibbs sampling strategy. The efficiency of the proposed fusion method is evaluated with respect to several state-of-the-art fusion techniques.
81 MIPST-02 Registration of Images With N-Fold Dihedral Blur
IEEE-2015 In this paper, we extend our recent registration method designed specifically for registering blurred images. The original method works for unknown blurs, assuming the blurring point-spread function (PSF) exhibits an N-fold rotational symmetry. Here, we also generalize the theory to the case of dihedrally symmetric blurs, which are produced by the PSFs having both rotational and axial symmetries .Such kind of blurs are often found in unfocused images acquired by digital cameras, as in out of focus shots the PSF typically mimics the shape of the shutter aperture. This makes our registration algorithm particularly well-suited in applications where blurred image registration must be used as a preprocess step of an image fusion algorithm, and where common registration methods fail, due to the amount of blur. We demonstrate that the proposed method leads to an improvement of the registration performance, and we show it to real images by providing successful examples of blurred image registration followed by depth-of-field extension and multichannel blind deconvolution.

82 MIPST-03 A Novel SURE-Based Criterion for Parametric PSF Estimation
IEEE-2015 We propose an unbiased estimate of a filtered version of the mean squared error—the blur-SURE (Stein’s unbiased risk estimate)—as a novel criterion for estimating an unknown point spread function (PSF) from the degraded image only. The PSF is obtained by minimizing this new objective functional over a family of Wiener processing. Based on this estimated blur kernel, we then perform nonblind deconvolution using our recently developed algorithm. The SURE-based framework is exemplified with a number of parametric PSF, involving a scaling factor that controls the blur size. A typical example of such parametrization is the Gaussian kernel. The experimental results demonstrate that minimizing the blur-SURE yields highly accurate estimates of the PSF parameters, which also result in a restoration quality that is very similar to the one obtained with the exact PSF, when plugged into our recent multi-Wiener SURE-LET deconvolution algorithm. The highly competitive results obtained outline the great potential of developing more powerful blind deconvolution algorithms based on SURE-like estimates.
83 MIPST-04 Histogram-Based Locality-Preserving Contrast Enhancement
IEEE-2015 Histogram equalization (HE), a simple contrast enhancement (CE) method, tends to show excessive enhancement and gives unnatural artifacts on images with high peaks in their histograms. Histogram-based CE methods have been proposed in order to overcome the drawback of HE, however, they do not always give good enhancement results. In this letter, a histogram-based locality-preserving CE method is proposed. The proposed method is formulated as an optimization problem to preserve localities of the histogram for performing image CE. The locality-preserving property makes the histogram shape of the enhanced image to be similar to that of the original image. Experimental results show that the proposed histogram-based method gives output images with graceful CE on which existing methods give unnatural results.
84 MIPST-05 An Efficient MRF Embedded Level Set Method for Image Segmentation
IEEE-2015 This paper presents a fast and robust level set method for image segmentation. To enhance the robustness against noise, we embed a Markov random field (MRF) energy function to the conventional level set energy function. This MRF energy function builds the correlation of a pixel with its neighbors and encourages them to fall into the same region. To obtain a fast implementation of
44
the MRF embedded level set model, we explore algebraic multigrid (AMG) and sparse field method (SFM) to increase the time step and decrease the computation domain ,respectively. Both AMG and SFM can be conducted in a parallel fashion, which facilitates the processing of our method for big image databases. By comparing the proposed fast and robust level set method with the standard level set method and its popular variants on noisy synthetic images, synthetic aperture radar (SAR) images, medical images, and natural images, we comprehensively demonstrate the new method is robust against various kinds of noises. In particular, the new level set method can segment an image of size 500 × 500 within 3 s on MATLAB R2010b installed in a computer with 3.30-GHz CPU and 4-GB memory.
85 MIPST-06 Robust Clutter Suppression and Moving Target Imaging Approach for Multichannel in Azimuth High-Resolution and Wide-Swath Synthetic Aperture Radar
IEEE-2015 This paper describes a clutter suppression approach and the corresponding moving target imaging algorithm for a multichannel in azimuth high-resolution and wide-swath (MC-HRWS) synthetic aperture radar (SAR) system. Incorporated with digital beaforming processing, MC-HRWS SAR systems are able to suppress the Doppler ambiguities to allow for HRWS SAR imaging and null the clutter directions to suppress clutter for ground moving target indication. In this paper, the degrees of freedom in azimuth for the multichannel SAR systems are employed to implement clutter suppression. First, the clutter and moving target echoes are transformed into the range compression and azimuth chirp Fourier transform frequency domain, i.e., coarse-focused images formation, when the clutter echoes are with azimuth Doppler ambiguity. Considering that moving targets are sparse in the imaging scene and that there is a difference between clutter and a moving target in the spatial domain, a series of spatial domain filters are constructed to extract moving target echoes. Then, using an extracted moving target echo, two groups of signals are formed, and slant-range velocity of a moving target can be estimated based on baseband Doppler centroid estimation algorithm and multilook cross-correlation Doppler centroid ambiguity number resolving approach. After the linear range cellmigration correction and azimuth focus processing, a well-focused moving target image can be obtained.

86 MIPST-07 Optimizing Template for Lookup-Table Inverse Halftoning using Elitist Genetic Algorithm
IEEE-2015 A template optimization method based on elitist genetic algorithm was proposed for lookup-table inverse halftoning. A mathematical model with constraint conditions was built to describe the template optimization problem.We solved this optimization problem by using elitist genetic algorithm and designed the details about encoding and decoding scheme, selection and reproduce, crossover, mutation, elitist strategy and fitness function according to the proposed optimization model. In experiments, we demonstrated the performance on Floyd-Steinberg error diffusion, Jarvis-Judice error diffusion, cluster dither, Bayer disperse dither and dot diffusion halftone images. According to our experiment study, our method approaches to the optimal result closer than the greedy algorithm and simulated annealing do. We suggested on cluster dither images but on other four kinds of halftone images.
87 MIPST-08 An Improved PFA With Aperture Accommodation for Widefield Spotlight SAR Imaging
IEEE-2015 This letter presents an improved polar format algorithm for nonlinear aperture and wide field spotlight synthetic aperture radar imaging. In the proposed algorithm, the chirp z transform is used for uniform range resampling, while the fast Gaussian grid nonuniform fast Fourier transform is employed to focus the nonuniform samples in azimuth. Additionally, the space variant post filtering is incorporated for eliminating the geometric distortion and marginal defocusing effects induced by wave front curvature. The effectiveness of the proposed algorithm is validated by simulation and real large scene Gotcha data set.
88 MIPST-09 A New Framework for SAR Multitemporal Data RGB Representation: Rationale and Products
IEEE-2015 This paper presents the multitemporal adaptive processing (MAP3) framework for the treatment of multitemporal synthetic aperture radar (SAR) images. The framework is organized in three major activities dealing with calibration, adaptability,and representation. The processing chain has been designed looking at the simplicity, i.e., the minimization of the operations needed to obtain the products, and at the algorithms’ availability in the literature. Innovation has been provided in the cross calibration step, which is solved introducing the variable amplitude levels equalization (VALE) method, through which it is possible to establish a common metrics for the measurement of the amplitude levels exhibited by the images of the series.

89 MIPST-10 Indicator Cokriging-Based Subpixel Mapping Without Prior Spatial Structure Information
IEEE-2015 Indicator cokriging (ICK) has been shown to be an effective subpixel mapping (SPM) algorithm. It is noniterative and involves few parameters. The original ICK-based SPM method,however, requires the semivariogram of land cover classes from prior information, usually in the form of fine spatial resolution training images. In reality, training images are not always available, or laborious work is needed to acquire them. This paper aims to seek spatial structure information for ICK when such prior land cover information is not obtainable. Specifically, the fine spatial resolution semivariogram of each class is estimated by the deconvolution process, taking the coarse spatial resolution semivariogram extracted fromthe class proportion image as input. The obtained fine spatial resolution semivariogram is then used to estimate class occurrence probability at each subpixel with the ICK method. Experiments demonstrated the feasibility of the proposed ICK with the deconvolution approach. It obtains comparable SPM accuracy to ICK that requires semivariogram estimated from fine spatial resolution training images. The proposed method extends ICK to cases where the prior spatial structure information is unavailable.
90 MIPST-11 Reversible Image Data Hiding with Contrast Enhancement
IEEE-2015 In this letter, a novel reversible data hiding (RDH) algorithm is proposed for digital images. Instead of trying to keep the PSNR value high, the proposed algorithm enhances the contrast of a host image to improve its visual quality. The highest two bins in the histogram are selected for data embedding so that histogram equalization can be performed by repeating the process. The side information is embedded along with the message bits into the host image so that the original image is completely recoverable. The proposed algorithm was implemented on two sets of images to demonstrate its efficiency. To our best knowledge, it is the first algorithm that achieves image contrast enhancement by RDH. Furthermore, the evaluation results show that the visual quality can be preserved after a considerable amount of message bits have been embedded into the contrast-enhanced images, even better than three specific MATLAB functions used for image contrast enhancement.

91 MIPST-12 Features, Color Spaces, and Boosting: New Insights on Semantic Classification of Remote Sensing Images
IEEE-2015 A major yet largely unsolved problem in the semantic classification of very high resolution remote sensing images is the design and selection of appropriate features. At a ground sampling distance below half a meter, fine-grained texture details of objects emerge and lead to a large intra class variability while generally keeping the between-class variability at a low level. Usually, the user makes an educated guess on what features seem to appropriately capture characteristic object class patterns. Here, we propose to avoid manual feature selection and let a boosting classifier choose optimal features from a vast Randomized Quasi- Exhaustive (RQE) set of feature candidates directly during training. This RQE feature set consists of a multitude of very simple features that are computed efficiently via integral images inside a sliding window. This simple but comprehensive feature candidate set enables the boosting classifier to assemble the most discriminative textures at different scale levels to classify a small number of broad urban land-cover classes.
92 MIPST-13 Continuous One-Way Detection of Available Bandwidth Changes for Video Streaming Over Best-Effort Networks
IEEE-2015 Video streaming over best-effort networks, such as the Internet, is now a significant application used by most Internet users. However, best-effort networks are characterized by dynamic and unpredictable changes in the available bandwidth, which adversely affect the quality of video. As such, it is important to have real-time detection mechanisms of bandwidth changes to ensure that video is adapted to the available bandwidth and transmitted at the highest quality. In this paper, we propose a Bayesian instantaneous end-to-end bandwidth change prediction model and method to detect and predict one-way bandwidth changes at the receiver. Unlike existing congestion detection mechanisms, which use network parameters such as packet loss probability, round trip time (RTT), or jitter, our approach uses weighted inter arrival time of video packets at the receiver side. Furthermore, our approach is continuous, since it measures available bandwidth changes with each incoming video packet, and therefore detects congestion occurrence in <200 ms, on average, which is significantly faster than existing approaches. In addition, it is a one-way scheme, since it only takes into account the characteristics of the incoming path.

93 MIPST-14 Compressed-Domain Ship Detection on Space borne Optical Image Using Deep Neural Network and Extreme Learning Machine
IEEE-2015 Ship detection on space borne images has attracted great interest in the applications of maritime security and traffic control. Optical images stand out from other remote sensing images in object detection due to their higher resolution and more visualized contents. However, most of the popular techniques for ship detection from optical space borne images have two shortcomings:1) Compared with infrared and synthetic aperture radar images, their results are affected by weather conditions, like clouds and ocean waves, and 2) the higher resolution results in larger data volume, which makes processing more difficult. Most of the previous works mainly focus on solving the first problem by improving segmentation or classification with complicated algorithms. These methods face difficulty in efficiently balancing performance and complexity. In this paper, we propose a ship detection approach to solving the a for mentioned two issues using wavelet coefficients extracted from JPEG2000 compressed domain combined with deep neural network (DNN) and extreme learning machine (ELM). Compressed domain is adopted for fast ship candidate extraction, DNN is exploited for high-level feature representation and classification, and ELM is used for efficient feature pooling and decision making.
94 MIPST-15 An Intelligent Monitoring System for Natural Gas Odorization
IEEE-2015 In this paper, we present the design of an intelligent monitoring system consisting of physical sensors and intelligent software for the automatic identification of the concentration of natural gas odorants in the environment. An optical-based sensor array was proposed comprising the hardware module. The software module employs wavelets filters and artificial neural networks to recognize the concentration of odorant in a natural gas sample. The objective is to help the natural gas odorization process by means of end point monitoring through the recognizing of the odorant concentration. The recognizing process uses a benchmark index, which measures the degrees of human perception of gas in the environment. In this way, the proposed system tries to mimic the human perception of a natural gas leak and helps one to indicate if more or less amount of odorant should be added into the gas pipeline.

95 MIPST-16 Feature Matching With an Adaptive Optical Sensor in a Ground Target Tracking System
IEEE-2015 We consider methods to address the optical feature aided remote sensing tracking problem for vehicles in a challenging environment. Our approach is to apply the dynamic data driven application systems computing paradigm to implement control of an adaptive sensor. This adaptive sensor acquires a panchromatic image while simultaneously allowing the collection of visible-near infrared spectral data at specified pixels. This sensor holds the promise of delivering the increased accuracy of targeted spectral sensing without the enormous data volume of full spectral images. The target of interest is optimally imaged by the sensor based on the target’s forecasted location and motion relative to the extracted content of the background. Background context is both extracted from the image and created from the Open Street Map road network. We describe the implementation of the tracking framework and testing of some of the components using simulated imagery created with the digital imaging and remote sensing image generation model.
96 MIPST-17 Capabilities of BIOMASS Tomography for Investigating Tropical Forests
IEEE-2015 The objective of this paper is to provide a better understanding of the capabilities of the BIOMASS tomography concerning the retrieval of forest biomass and height in tropical areas. The analysis presented in this paper is carried out on airborne data acquired by Office National d’Etudes et de Recherches Aérospatiales (ONERA) over the site of Paracou, French Guiana, during the European Space Agency campaign TropiSAR. This high-resolution data set (125-MHz bandwidth) was reprocessed in order to generate a new data stack consistent with BIOMASS as for the bandwidth (6 MHz) and the azimuth resolution (about 12 m). To do this, two different processing approaches have been considered. One approach consisted of degrading the resolution of the airborne data through the linear filtering of raw data, followed by standard SAR processing. The other approach consisted of recovering the 3-D distribution of the scatterers at a high resolution, which was then reprojected onto the BIOMASS geometry. The latter procedure allows us to obtain a data stack that is the most realistic emulation of BIOMASS imaging capabilities. In both approaches, neither ionospheric disturbances nor temporal decorrelation has been considered.

97 MIPST-18 Soil Moisture Estimation Under Tropical Forests Using UHF Radar Polarimetry
IEEE-2015 In this paper, we report on the performance of a semiempirical algorithm for the retrieval of soil moisture (SM) under dense tropical forests using ultrahigh frequency (UHF) polarimetric synthetic aperture radar (SAR) data. The algorithm is a simplification of a 3-D coherent model of forest canopy based on the distorted Born approximation (DBA). The simplified model reduces the number of parameters and preserves the three dominant scattering mechanisms of volume, volume–surface, and surface for three polarized backscattering coefficients, i.e., σHH, σHV, and σVV, at UHF frequencies. The inversion process uses the Levenberg–Marquardt nonlinear least squares method to estimate the three model parameters: vegetation aboveground biomass, integrated SM up to a certain depth, and surface roughness. The performance of the inversion process is examined by first using simulation data where the initial values of the inversion process vary randomly and then using airborne UHF SAR data acquired in Costa Rica over La Selva Biological Station. The results with simulated data show that the inversion process is not significantly sensitive to initial values considering they are in the range of ±50% of the true value.
98 MIPST-19 A Novel Range Grating Lobe Suppression Method Based on the Stepped-Frequency SAR Image
IEEE-2015 The magnitude error and phase error (MEPE) in the transfer function of a stepped-frequency synthetic aperture radar (SAR) system results in a periodic MEPE in the synthesized wideband waveform, which induces the grating lobes in the high-resolution range profile. In this letter, a novel grating lobe suppression method based on the SAR image is proposed. In the paired-echo theory, a single sinusoidal term of the periodic MEPE in the frequency domain induces a pair of grating lobes in the time domain. Based on the magnitudes and phases of a strong scatterer and its grating lobes in the SAR image, the sinusoidal terms in the periodic MEPE can be estimated using the proposed method. By compensating for the estimated sinusoidal terms in the spectrum reconstruction, the corresponding grating lobes can be suppressed to the background level of the SAR image. The validity of the proposed method has been demonstrated using computer simulations and experiments based on real data.

99 MIPST-20 Multi-Task Bayesian Compressive Sensing Exploiting Intra-Task Dependency
IEEE-2015 In this letter, we propose a multi-task compressive sensing algorithm for the reconstruction of clustered sparse entries based on hierarchical Bayesian framework. By extending a paired spike-and-slab prior to a general multi-task model, the proposed algorithm has the capability of modeling both inter-task and intra-task dependencies of the observation data. The latter is achieved by imposing a clustered prior on non-zero entries and finds applications in radar where targets exhibit spatial extent. Simulation results verify that the proposed algorithm outperforms state-of-the-art group sparse Bayesian learning algorithms.
100 MIPST-21 Recognition of Genuine Smiles
IEEE-2015 Automatic distinction between genuine (spontaneous) and posed expressions is important for visual analysis of social signals. In this paper, we describe an informative set of features for the analysis of face dynamics, and propose a completely automatic system to distinguish between genuine and posed enjoyment smiles. Our system incorporates facial land marking and tracking, through which features are extracted to describe the dynamics of eyelid, cheek, and lip corner movements. By fusing features over different regions, as well as over different temporal phases of a smile, we obtain a very accurate smile classifier. We systematically investigate age and gender effects, and establish that age-specific classification significantly improves the results, even when the age is automatically estimated. We evaluate our system on the 400-subject UvA-NEMO database we have recently collected, as well as on three other smile databases from the literature.
101 MIPST-22 DietCam: Multi-View Food Recognition Using a Multi-Kernel SVM
IEEE-2015 Food recognition is a key component in evaluation of everyday food intakes, and its challenge is due to intraclass variation. In this paper, we present an automatic food classification method, DietCam, which specifically addresses the variation of food appearances. DietCam consists two major components, ingredient detection and food classification. Food ingredients are detected through a combination of a deformable part-based model and a texture verification model. From the detected ingredients,food categories are classified using a multi-view multikernel SVM. In the experiment, DietCam presents reliability and outperformance in recognition of food with complex ingredients on a database of 55 food types with 15262 food images.

102 MIPST-23 Contributions to Automatic Target Recognition Systems for Underwater Mine Classification
IEEE-2015 This paper deals with several original contributions to an automatic target recognition (ATR) system, which is applied to underwater mine classification. The contributions concentrate on feature selection and object classification. First, a sophisticated filter method is designed for the feature selection. This filter method utilizes a novel feature relevance measure, the composite relevance measure (CRM). Feature relevance measures in the literature (e.g., mutual information and relief weight) evaluate the features only with respect to certain aspects. The CRM is a combination of several measures so that it is able to provide a more comprehensive assessment of the features. Both linear and nonlinear combinations of these measures are taken into account.
103 MIPST-24 Robust and high capacity watermarking for image based on DWT-SVD
IEEE-2015 In this paper, we propose a blind digital image water marking technique by combining Discrete Wavelet Transform (DWT) with Singular Value Decomposition (SVD) to improve the robustness and the capacity. In detail, Singular Values (SVs) of watermarks are replaced with the suitable SVs of HH sub-bands of the original images. Additionally, our method generates keys that ensures the security for the watermarks in the embedding and the extraction process. Experiments on images for digital watermarking attacked by Stirmark Benchmark 4.0 tool show that our method is more robust, imperceptible and higher capacity than others’.
104 MIPST-25 Hybrid Compression of Hyperspectral Images Based on PCA With Pre-Encoding Discriminant Information
IEEE-2015 t has been shown that image compression based on principal component analysis (PCA) provides good compression efficiency for hyperspectral images. However, PCA might fail to capture all the discriminant information of hyperspectral images, since features that are important for classification tasks may not be high in signal energy. To deal with this problem, we propose a hybrid compression method for hyperspectral images with pre-encoding discriminant information. A feature extraction method is first applied to the original images, producing a set of feature vectors that are used to generate feature images and then residual images by subtracting the feature-reconstructed images from the original ones. Both feature images and residual images are compressed and transmitted.

105 MIPST-26 Secure Reversible Image Data Hiding over Encrypted Domain via Key Modulation
IEEE-2015 This work proposes a novel reversible image data hiding (RIDH) scheme over encrypted domain. The data embedding is achieved through a public key modulation mechanism, in which access to the secret encryption key is not needed. At the decoder side, a powerful two-class SVM classifier is designed to distinguish encrypted and non-encrypted image patches, allowing us to jointly decode the embedded message and the original image signal. Compared with the state-of-the-arts, the proposed approach provides higher embedding capacity, and is able to perfectly reconstruct the original image as well as the embedded message. Extensive experimental results are provided to validate the superior performance of our scheme.
106 MIPST-27 Context-Based Predictor Blending for Lossless Colour Image Compression
IEEE-2015 Images are typically non-stationary signals. If prediction is applied in a linear fashion, it must be combined with a technique that takes this characteristic into account. In general, images can be either regarded as piecewise two-dimensional autoregressive processes or they are handled in a block-wise manner. This paper presents a novel prediction technique, which treats the image data as an interleaved sequence generated by multiple sources. The challenge is to de-interleave the sequence and to compute prediction weights for each sub-source separately. The proposed approach adaptively determines the sub-sources based on the textures surrounding the pixels. The new linear prediction technique is combined with template-matching prediction and a blending method is proposed which considers the correlation between the predictors’ estimates.
107 MIPST-28 Reversable data hiding in encrypted image with distributed source ecncoding
IEEE-2015 This paper proposes a novel scheme of reversible data hiding (RDH) in encrypted images using distributed source coding (DSC). After the original image is encrypted by the content owner using a stream cipher, the data-hider compresses a series of selected bits taken from the encrypted image to make room for the secret data. The selected bit series is Slepian-Wolf encoded using low density parity check (LDPC) codes. On the receiver side, the secret bits can be extracted if the image receiver has the embedding key only. In case the receiver has the encryption key only, he/she can recover the original image approximately with high quality using an image estimation algorithm.

108 MIPST-29 Nighttime Visibility Analysis and Estimation Method in the Presence of Dense Fog
IEEE-2015 Compared with daytime, a larger proportion of road accidents happens during nighttime. The altered visibility for drivers partially explains this situation. It becomes worse when dense fog is present. In this paper, we first define a standard night visibility index, which allows specifying the type of fog that an advanced driver assistance system should recognize. A methodology to detect the presence of night fog and characterize its density in images grabbed by an in-vehicle camera is then proposed. The detection method relies on the visual effects of night fog. A first approach evaluates the presence of fog around a vehicle due to the detection of the backscattered veil created by the headlamps. In this aim, a correlation index is computed between the current image and a reference image where the fog density is known. It works when the vehicle is alone on a highway without external light sources.
MATLAB-DIGITAL COMMUNICATION
109 MCMST-1 ICI Self-Cancellation with Cosine Windowing in OFDM transmitters Over Fast Time-Varying Channels
IEEE-2015 We propose the application of cosine windowing for the orthogonal frequency-division multiplexing (OFDM) systems to self-cancel inter carrier interference (ICI) in fast time-varying channels prior to receptions. With a time-domain cosine window immediately after the inverse discrete Fourier transform (IDFT) unit in OFDM transmitters, the ICI fractions from adjacent subcarriers significantly cancel one another at the expense of the orthogonally violation among subcarriers in the main lobe. As a result, the frequency-domain channel matrix reshaped by the cosine windowing can be closely approximated to a strictly banded matrix. In the complex exponential basis expansion model (CE-BEM), we present the estimation of the channel matrix with the assistance of the pilot clusters.
110 MCMST-2 Convergence Constrained Multiuser Transmitter-Receiver Optimization in Single-Carrier FDMA
IEEE-2015 Convergence constrained power allocation (CCPA)in single-carrier multiuser (MU) single-input multiple-output (SIMO) systems with turbo equalization is considered in this paper. In order to exploit the full benefit of the iterative receiver, its convergence properties need to be taken into account also at the transmitter side. The proposed scheme can guarantee that the desired quality of service (QoS) is achieved after a sufficient number of iterations. We propose two
55
different successive convex approximations for solving the non-convex power minimization problem subject to user specific QoS constraints. The results of an extrinsic information transfer (EXIT) chart analysis demonstrate that the proposed CCPA scheme can achieve the design objective. Numerical results show that the proposed schemes can achieve superior performance in terms of power consumption as compared to linear receivers with and without precoding, as well as to the iterative receiver without precoding.
111 MCMST-3 Beam forming for Multiuser MIMO-OFDM Interference Channels With Multipath Diversity
IEEE-2015 This paper presents three beam forming designs for multiuser multiple-input and multiple-output with orthogonal frequency-division multiplexing, where the transmit and receive beam formers are obtained iteratively with closed-form steps. In the first case, the transmit (Tx) beam formers are set and the receive (Rx) beam formers are calculated. It works by projecting the Tx beam formers into a null space of appropriate channels .This eliminates one interference term for each user. Then the Rx beam former for each user maximizes its instantaneous signal to noise ratio (SNR) while satisfying an orthogonality condition to eliminate the remaining interferences. The second case is jointly optimizing the Tx and Rx beam formers from constrained SNR maximization. It uses the results from the first case. The third case is also for joint optimization of Tx–Rx beam formers but combines constrained SNR and signal-to-interference-plus-noise ratio maximization. The minimum number of antennas required is derived as part of the formulation.
112 MCMST-4 Quantum Spread Spectrum Multiple Access
IEEE-2015 We describe a quantum multiple access scheme that can take separate single photon channels and combine them in the same path. We propose an add-drop multiplexer that can insert or extract a single photon into an optical fiber carrying the Sub its of all the other users. The system follows the principle of code division multiple access, a spread spectrum technique widely used in cellular networks.
113 MCMST-5 New RLL Decoding Algorithm for Multiple Candidates in Visible Light Communication
IEEE-2015 In this letter, we propose a new decoding algorithm based on a soft run-length limited (RLL) decoding in visible light communication (VLC) with on-off keying modulation and Reed–Solomon codes. Conventional RLL codes are used for dimming adjustments in VLC; however, in our receiver model, the proposed RLL
56
decoder produces one or multiple candidates with greater probabilities to enhance the throughput in the VLC system. We also propose a selection method based on a cyclic redundancy check among multiple candidates. A significant advantage of our proposed method is that it leads to performance enhancement without any change in the transmitter in VLC systems.
114 MCMST-6 Multi-Tap Equalization for Performance Improvement in Optical Fast OFDM Systems
IEEE-2015 We show that multi-tap equalization can significantly enhance the tolerance to laser frequency instability and phase noise in optical fast orthogonal frequency division multiplexing (OFDM) systems. We demonstrate the transmission of a 38-Gb/s 16 quadrature amplitude modulation coherent optical fast OFDM signal over 1000-km single-mode fiber using different types of lasers. It is shown that with this technique, the receiver sensitivity can be greatly improved and overhead for carrier frequency offset estimation to track the wavelength can be reduced for commercial lasers. This verifies the benefits of the technique in a continuous-mode optical communication system. We also show that the performance of multi-tap equalization in optical fast OFDM can be better than that in conventional OFDM, and an experiment using lasers with frequency modulation to emulate frequency oscillating effect during wavelength transition shows that optical fast OFDM .
115 MCMST-7 A Multistage CPE Scheme Based on Crossed Constellation Transformation for M-QAM
IEEE-2015 A multistage carrier phase estimation (CPE) scheme for any m-ary quadrature amplitude modulation (QAM) formats is proposed and analyzed in coherent optical communication systems. The scheme is based on the crossed constellation transformation algorithm that is transparent to all modulation formats whose constellations are on the square grid. Simulation results show that the hardware complexity of the proposed CPE scheme can be significantly reduced by the group factors of 6.1/8.6, 4.7/6, and 2.6/3.3 (in the form of multipliers/adders) for 32-QAM, 64-QAM, and 128-QAM compared with the single stage blind phase search algorithm. In 32-QAM, 64-QAM, and 128-QAM, coherent optical communication systems with 1-dB SNR penalty at bit error rate is 1 × 10−2, the comparable line width symbol duration can be reached with the values of 6 × 10−5, 4 × 10−5, and 8 × 10−6, respectively.

116 MCMST-8 Efficient Chromatic Dispersion Precompensation for Coherent Optical OFDM
IEEE-2015 To reduce the guard interval, short-cyclic-prefix coherent optical orthogonal frequency division multiplexing (CO-OFDM) divides a band into two sub bands and precompensates for chromatic dispersion (CD) with timing offset. Implementation using full band inverse discrete Fourier transformations (IDFTs), however, can excessively increase hardware complexity. We propose an efficient hardware implementation of IDFT with timing offsets for short-cyclic-prefix CO-OFDM. In addition, the residual inter sub band CD induced by quantized timing offset is compensated using subcarrier-based phase rotation. By increasing the number of sub bands efficiently and compensating for the residual inter sub band CD, the transmission performance can be improved. Simulation results show 112-Gb/s single-channel transmission over a 2250-km standard single mode- fiber with polarization division multiplexing 16 quadrature amplitude modulation (PDM-16 QAM) using 128 DFT with a 16 guard interval.
117 MCMST-9 Gaussian Conditional Random Fields for Aggregation of Operational Aerosol Retrievals
IEEE-2015 We present a Gaussian conditional random field model for the aggregation of aerosol optical depth (AOD) retrievals from multiple satellite instruments into a joint retrieval. The model provides aggregated retrievals with higher accuracy and coverage than any of the individual instruments while also providing an estimation of retrieval uncertainty. The proposed model finds an optimal temporally smoothed combination of individual retrievals that minimizes the root-mean-squared error of AOD retrieval. We evaluated the model on five years (2006–2010) of satellite data over North America from five instruments (Aqua and Terra MODIS, MISR, SeaWiFS, and the Ozone Monitoring Instrument), collocated with ground-based Aerosol Robotic Network ground-truth AOD readings, clearly showing that the aggregation of different sources leads to improvements in the accuracy and coverage of AOD retrievals.
118 MCMST 10 Joint Power Splitting and Antenna Selection in Energy Harvesting Relay Channels
IEEE-2015 The simultaneous wireless transfer of information and power with the help of a relay equipped with multiple antennas is considered in this letter, where a “harvest-and-forward” strategy is proposed. In particular, the relay harvests energy and obtains information from the source with the radio-frequent signals by jointly using the antenna selection (AS) and power splitting (PS) techniques, and then the processed information is
58
amplified and forwarded to the destination relying on the harvested energy. This letter jointly optimizes AS and PS to maximize the achievable rate for the proposed strategy. Considering that the joint optimization is according to the non-convex problem, a two-stage procedure is proposed to determine the optimal ratio of received signal power split for energy harvesting, and the optimized antenna set engaged in information forwarding. Simulation results confirm the accuracy of the two-stage procedure, and demonstrate that the proposed “harvest-and-forward” strategy outperforms the conventional amplify-and-forward (AF) relaying and the direct transmission.
119 MCMST 11 Compressive Sensing and Reception for MIMO-OFDM Based Cognitive Radio
IEEE-2015 This paper explores a novel receiver architecture for multiple-input multiple-output (MIMO) and orthogonal frequency division multiplexing (OFDM) based cognitive radio (CR) that utilizes compressive sensing (CS) technique. Assuming that a limited number of subcarriers are used simultaneously in one MIMO-OFDM channel, we show that the conventional MIMO receiver can be replaced with the proposed receiver to compressively sample signals. In the proposed reception architecture, signals from multiple antennas are mixed and sampled with less hardware by exploiting the sparsity in the OFDM channel usage. Applying the CS technology to the receiver directly reduces the power consumption in mixed signal circuit which is attributable to less number of analog-to-digital converters (ADCs). A new streamlined algorithm for digital signal processing (DSP) to recover the compressively sensed data is also devised. Besides the simplification of the signal sensing, the simulation results also show that the reception fidelity of the proposed architecture outperforms that of the conventional maximum likelihood (ML) MIMO detector when the channel is lightly loaded.

120 MCMST 12 Spatio-Temporal Flame Modeling and Dynamic Texture Analysis for Automatic Video-Based Fire Detection
IEEE-2015 Every year, a large number of wildfires all over the world burn forested lands, causing adverse ecological, economic, and social impacts. Beyond taking precautionary measures, early warning and immediate response are the only ways to avoid great losses. To this end, in this paper we propose a computer vision approach for fire-flame detection to be used by an early warning fire monitoring system. Initially, candidate fire regions in a frame are defined using background subtraction and color analysis based on a nonparametric model. Subsequently, the fire behavior is modeled by employing various spatio-temporal features, such as color probability, flickering, spatial, and spatiotemporal energy, while dynamic texture analysis is applied in each candidate region using linear dynamical systems and a bag of systems approach. To increase the robustness of the algorithm, the spatio-temporal consistency energy of each candidate fire region is estimated by exploiting prior knowledge about the possible existence of fire in neighboring blocks from the current and previous video frames. As a final step, a two-class support vector machine classifier is used to classify the candidate regions. Experimental results have shown that the proposed method outperforms existing state-of-the-art algorithms.

MCMST 13 Spectrum Allocation in Cognitive Radio Networks using Multi-Objective Differential Evolution Algorithm
IEEE-2015 In the existing literature the forced termination probability is analyzed after the completion of spectrum allocation (SA) process. Since the forced termination probability depends on the allocation results, it is necessary to take the termination probability into account during the allocation process. In this paper, a two dimensional Markov model is used for analyzing the spectrum access. The Markov process assumes the mean arrival time of primary and secondary users and calculates the forced termination probability. In the current work, the forced termination probability is considered as one objective function along with three network utility functions namely Max- Sum-Reward, Max-Min-Reward and Max-Proportional-Fair to improve the quality of service. Finally the spectrum allocation process is formulated as a multi-objective optimization problem consisting of the above mentioned four objective functions and solved by using multi-objective differential
60
evolution (MODE) algorithm. The performance of MODE algorithm is compared with non dominated sorting genetic algorithm II (NSGA-II) for solving the SA problem. The simulation results show that MODE performs better compared to NSGA-II algorithm in terms of timing complexity and pare to optimal solutions.

MCMST 14 Time–Frequency Joint Sparse Channel Estimation for MIMO-OFDM Systems
IEEE-2015 This letter proposes a time-frequency joint sparse channel estimation for multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems under the framework of structured compressive sensing (CS). The proposed scheme first relies on a pseudorandom preamble, which is identical for all transmit antennas, to acquire the partial common support by utilizing the sparse common support property of the MIMO channels. Then, a very small amount of frequency-domain orthogonal pilots are used for the accurate channel recovery. Simulation results show that the proposed scheme demonstrates better performance and higher spectral efficiency than the conventional MIMO-OFDM schemes. Moreover, the obtained partial common support can be further utilized to reduce the complexity of the CS algorithm and improve the signal recovery probability under low signal-to-noise-ratio conditions.

MCMST 15 Performance of OFDM Systems With Best-m Feedback, Scheduling, and Delays for Uniformly Correlated Subchannels
IEEE-2015 Contemporary cellular standards, such as Long Term Evolution (LTE) and LTE-Advanced, employ orthogonal frequency-division multiplexing (OFDM) and use frequency domain scheduling and rate adaptation. In conjunction with feedback reduction schemes, high downlink spectral efficiencies are achieved while limiting the uplink feedback overhead. One such important scheme that has been adopted by these standards is best-m feedback, in which every user feeds back its m largest subchannel (SC) power gains and their corresponding indices.We analyze the single cell average throughput of an OFDM system with uniformly correlated SC gains that employs best-mfeedback and discrete rate adaptation. Our model incorporates three schedulers that cover a wide range of the throughput versus fairness tradeoff and feedback delay. We show that, for small m, correlation significantly reduces average throughput with best-mfeedback. This result is pertinent as even in typical dispersive channels, correlation is high.

MCMST 16 Power Efficient Scattered Pilot Channel Estimation for FBMC/OQAM
IEEE-2015 Filter bank multicarrier transmission with offset-QAM (FBMC/OQAM) is a promising candidate waveform for the next mobile communication systems as it is well suited for many new scenarios and challenges like improved spectral efficiency, spectrum sharing approaches or high mobility scenarios. It does not require a cyclic prefix (CP) leading to a higher spectral efficiency than orthogonal frequency division multiplexing with CP (CP-OFDM) and the flexibility of the transmit and receive filters enables higher throughput in spectral sharing and high mobility scenarios. One aspect to be considered is efficient channel estimation that is needed in order to realize these gains. As the classical channel estimation used for CP-OFDM cannot be applied directly to FBMC/OQAM, new competitive solutions are needed. One promising solution for the pilot design suited for FBMC introduces an auxiliary pilot (precoding symbol) that nullifies the intrinsic interference at the pilot position, but this leads to increased power on these auxiliary pilots.

MCMST 17 Performance Analysis of Fast Tracking Equalization for SC-FDMA and OFDM systems under multipath fading environment
IEEE-2015 In this paper, SC-FDMA and OFDM systems with fast tracking equalizer based on RLS algorithm in multipath fading environments are proposed. In the proposed SC-FDMA and OFDM system with fast tracking equalizer, known-reference signals are allocated to the 1st slot of transmitting slots on each subcarrier at the transmitter. The transmitted signals are equalized with the reference signals on the frequency domain at the receiver. The channel information is updated by performing estimation based on RLS algorithm with the reference signals during the signal transmission, and the fast tracking equalization is performed. In order to confirm the transmission performance with fast tracking equalizer, computer simulations about BER and PAPR are carried out. As the results of computer simulation, the improvement of BER for the systems with equalizer based on LMS algorithm is about twice higher than the conventional system with only the initial equalization.

MCMST 18 On Demand SINR based Scheduling Algorithm (ODSSA) for Mobile Uplink Communication in LTE Networks
IEEE-2015 Long Term Evolution (LTE) a Third Generation Partnership Project (3GPP) is developed for multimedia applications on mobile user equipment with very high data rates of the order 75/300 Mbps and low latency of 10msec. The high data rates are achieved by using SC-FDMA radio access mechanism for uplink communication and OFDM access mechanism for downlink. The performance can be
62
further improved by scheduling the user data in an efficient manner considering channel characteristics as well as its QOS parameters, thereby allocating the resources to maximize the throughput. The Packet Scheduler helps in handling the LTE data traffic by allocating the resources both in time and frequency dimension. In this paper, we propose a novel scheduling algorithm that allocates maximum resources for the random users depending on their channel SNR condition with main focus on the data flow behavior.

127 MSPST 1 High-Precision, Permanently Stable, Modulated Hopping Discrete Fourier Transform
IEEE-2015 A new modulated hopping Discrete Fourier Transform (mHDFT) algorithm which is characterized by its merits of high accuracy and constant stability is presented. The proposed algorithm, which is based on the circular frequency shift property of DFT, directly moves the DFT bin to the position of, and computes the DFT by incorporating the successive DFT outputs with arbitrary time hop . Compared to previous works, since the pole of mHDFT precisely settles on the unit circle in the Z-plane, the accumulated errors and potential instabilities, which are caused by the quantization of the twiddle factor, are always eliminated without increasing much computational effort. The numerical simulation results verify the effectiveness and superiority of the proposed algorithm.
128 MSPST 2 A Joint QRS Detection and Data Compression Scheme for Wearable Sensors
IEEE-2015 This paper presents a novel electrocardiogram (ECG) processing technique for joint data compression and QRS detection in awireless wearable sensor. The proposed algorithm is aimed at lowering the average complexity per task by sharing the computational load among multiple essential signal-processing tasks needed for wearable devices. The compression algorithm, which is based on an adaptive linear data prediction scheme, achieves a lossless bit compression ratio of 2.286x. The QRS detection algorithm achieves a sensitivity (Se) of 99.64% and positive prediction (+P) of 99.81% when tested with the MIT/BIH Arrhythmia database. Lower overall complexity and good performance renders the proposed technique suitable for wearable/ambulatory ECG devices.

129 MVPST 1 Authenticating Using Secret Key in Digital Video Watermarking Using 3-Level DWT
IEEE-2015 Authenticating watermarking is nothing but inserting a hidden object in order to detect deceitful alteration by hackers. The object may be in terms of a secret key or password etc. There are quite few numbers of authentication methods are available for videos. Resent developers in digital video and internet technology helps the common user to easily produce illegal copies of videos. In order to solve the copyright protection problem and deceitful alteration by hackers of videos, several water marking schemes have been widely used. Very few authenticating of watermarking schemes have been produced for defining the copyrights of digital video. The process of Digital watermark embeds the data called watermark in digital media like image, video, audio file etc. so that it can be claimed for rights. The paper represents the complete software implementation of 3-Level DWT algorithms and to have more secure data a secret key is used. The secret key is given to watermark image during embedding process and while extracting the watermark image the same secret key is used. To check effectiveness of the watermark video MSE and PSNR parameters are used.

MAPST 1 Improved Lip Contour Extraction For Visual Speech Recognition
IEEE-2015 Automatic speech recognition systems perform on acoustic speech signals and therefore they are unreliable in noisy environments. Visual speech features such as lip movements of a speaker can make the speech recognition system robust. To track the lip movements, lip contour extraction is a necessary step and plays a crucial role in the visual speech recognition. In this paper, we propose a new method for lip contour extraction using fuzzy clustering with elliptic shape information and active contour model. In this method, we combined both image and model based methods to improve the performance of lip contour extraction. Our proposed lip contour extraction method outperforms few of existing lip contour extraction methods. We applied our lip contour extraction method on 3600 lip images from Vid Limit database and results are found better than the few existing lip contour extraction methods.
