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


CommonSense approach

� Open sensor information market� Reuse of sensors/machines in different applications� Leveraging existing network solutions

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


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
