Introduction Different

architectures Web Service

Approach Wireless

Connectivity WSN requirements An experimental

Study

Internet of things& its need

• The transformation of Paradigm

• Extending network to “Things"

• Making network more Pervasive

• Application limited only by imagination

Smart city Concept

• Efficient and effortless administration• Quality of service• Quality of living• Communication infrastructure

Areas of exploiting IoT▸ Structural Health▸ Waste Management▸ Air quality▸ Noise Monitoring▸ Traffic Congestion▸ City Energy consumption▸ Smart lighting

“

Architecture

Sensing layer

Access layer

Middleware layer

Application layer

Architectural reference Model ITU proposed architecture

Web Service Approach ▸ Representational State Transfer

`

Protocol stack

Use of XML Parsing of messages Need for EXI Types of EXI

processors

Schema less encoding

Schema informed encoding

Data formats

Application and Transport layers

▸ Problem with HTTP

▸ Need for CoAP

Network layer▸ Present addressing scheme▸ IPV6 addressing scheme

Wireless Connectivityo Frequency bands and

worldwide regulationso Communication Protocolso Network Rangeo Network Topologyo Standards and interoperability

Frequency bands and worldwide regulations

▸ Can’t be limited to single frequency

▸ Common frequency 2.4 GHz

Communication Protocols

Link

• Convert bits to radio signals

Network• Routes the data

Transport • Arranges the sessions

Application • End user controllability

Network range & Topology

Standards & interoperability

Device framework

• Backend servers

• Gateways

• IoT peripheral Nodes

An Experimental Study

“▸ Collecting environmental data

▸ Monitoring Public street lighting

Places where IoT is incorporated

Smart Environment &Street lighting system▸ Geographical localization▸ Sensors used-Photometer

sensors▸ Form 6LoWPAN multihop cloud▸ IPV6 routing protocol provided▸ WSN gateway

A glance at temperature and humidity data

Data collected from Temperature and Humidity sensors

“Data collected from Photometer & quality check sensor

ConclusionTarget of different companies

Aims at shaping a better future
