M2M today...
� ”M2M” is already a well established market– A number of solutions providers– Telematics, health-care, metering, monitoring
� Currently enterprise applications– drivers are cost reduction, efficiency, timeliness,
and safety� Solutions-oriented with vertical implementations
– proprietary solutions– re-invention of the wheel across solutions– resulting in costly solutions holding back market
� Fragmentation– wide-spread application domain– dedicated and proprietary technologies

...and looking forward
� Deployment consolidation in different enterprise segments?– Vehicle installations with multiple stakeholders
� road authorities, insurance companies, manufacturers– Home/building environment
� AMR, security, surveillance, home automation
� Authorities and national interests– Sustainable society and energy consumption– Home healthcare for growing aged population– Road infrastructure, toll and safety– ... and more growing interests
� Consumer segment next!– Convenience in daily life
� ”my life organizer”, ”assets” like children, pets and belongings,– Life-style
� social networking and real-world blogging, gaming– Communications- and content-centric services
� enrichment and extended control via sensor information– Mobile phone is a ubiquitous device
� Different possible roles and with increasing sensing capabilities

Future technology environment
� We imagine a wide variety of sensor networks:– Heterogeneity in terms of manufacturers
� OEMs / Re-sellers– Heterogeneity in terms of capability of sensors
� CPU / Memory / Storage / nano-technology– Heterogeneity in terms of networking technologies
� Zigbee / Wibree / Acoustic / Free Space Optics– Heterogeneity in terms of applications
� Consumer / Enterprise / Security– Heterogeneity in terms of client devices
� PCs / Mobile Phones / MIDs
� Heterogeneity on all levels

Wanted approach
� Break the vertical silos apart intotheir components
� Data & services are nowrecombinable – a serviceoriented approach
� Multiple stakeholders:– Users– WSN providers– Application service providers– M2M providers
� Enable the creation of newfunctionality without deploying anentirely new silo
� 3rd parties are brought into thegame

Architecture approaches
� Client/Servera.k.a Two Tier architecture
– Very common architecture– Easy to deploy– Foundation of the Web and
much more� Challenges to C/S
– Management: How tomanage many WSNs?
– Scalability: Every app has alink to every WSN?
– Security: Where to do AAA?– Service composition:
Mashups which require morecomputational power than amobile phone / MID?

� Middlewarea.k.a Three Tier architecture
– Also popular for distributedapplications
– Provides interoperabilitysupport by design
– Adds extra complexity to thesystem
� Following advantages:– Management: central point
to manage WSNs– Scalability: Many-to-many
connections unnecessary– Security: central point
natural place to do AAA– Service composition:
Middleware infrastructurecan be as powerful asnecessary without mobilityrequirements

Broker and processing functionality� Narrow convergence waist between
– Heterogeneous sensor networks below– Applications with diverse requirements on top
� Provides a set of enablers for all types of applications– Information exchange– Sensor network discovery– Data processing– Aggregation of atomic sensor network services (sensor mash-ups)– Common functions, like average over time and location
� Subsystems– Service Control Function
� Controls interaction with all external parties� Analyzes high level service requests from applications
– Request Analyzer� Decision engine decomposes requests from application to multiple
individual information requests, recomposes aggregated answer– Service Registry
� Database containing registration descriptions of attached WSNs� Available services, access policies and useful query attributes
such as geographical coverage or position

Global collaboration and sensing reqs
� Sensor information providers– Individuals, sensors embedded into everyday objects,
companies using sensor information to support ownbusiness processes, commercial sensor network operators
� Multi-provider environment– Community of providers offering horizontal solutions
� Open information market– Sensor information shared– Contributed to community and social services– Sold to interested parties
© Ericsson AB 2008 From Vertical to Horizontal 2008-05-1415
Business models and incentive reqs
� Business solution has to facilitate numerous, small ad-hoc financial transactions
� Incentives to sensor network owners needed to maketheir networks available and accessible
– Community and social networks� Incentive: access to the community/social network
– Commercial application� Incentive?
– Value of a WSN contribution variable� Accuracy, location, number of other similar sensors
– Fair remuneration to each WSN involved in providing theservice

Technology requirements� End-user side
– Mobile Phone must be in the picture� Information Provider� Information Gateway� Information Consumer
– Intuitive interaction is critical– Service delivery independent of User Equipment
� Communications infrastructure– Reuse mobile network infrastructure enablers where possible
� Location, AAA, IMS, etc.– New network procedures for handling large number of devices
� MSISDN, radio and core network, subscriptions handling, etc.– New traffic models
� System should be resilient to different traffic patterns
� Sensor information services– Harmonization of Information
� Sensor Information� Actuator Information
– Standardization of Information Semantics– Automatic Service Composition

Technology requirements cont’d� Operations
– Scalability & Heterogeneity� Number and Type of Sensors Actuators large
– Plug & play� Dynamic system update when sensors appear/disappear
� Multi purpose sensor actuator networks– Avoid vertical silos, re-use sensor data for multiple applications
� Security, privacy and trust– Sensors produce both explicit and implicit information about users
sometime without their consent– Actuators may harm users
� Enhancing existing services– Enhanced communication services
� e.g. Sensor information transmitted during a phone/video call

Summary
� Towards a consumer mass market– Usage of M2M and WSN will expand beyond the Enterprise
segment
� Heterogenity– The M2M technology landscape will continue to be
heterogeneous in many parts
� A three-tier architecture is required– diverse technologies, deployments and applications
towards sound business
� Standardization– A number of requirements need to be fulfilled, many of
them will need standardization
