  2. M2M Communication Overview • M2M? • Example: eCall • M2M ? IoT • M2M roots • Device characteristics • Devices ↔ Applications • M2M Maturity • Standards Organizations • ETSI M2M standard specifications • ETSI M2M Architecture • TC M2M – High Level Architecture • Network misalignment • Communication in M2M area network • oneM2M

  3. M2M Communication M2M? • M? Machine/Mobile/Man • M2(CN2)MMachine – to – Communication Network – to – machine • elastic boundaries • Who is in command? Human or device? (Smartphone vs Smart metering, Kindle browsing vs buying eBook) [1] p.2–3.

  4. M2M Communication Example: eCall http://itcafe.hu/dl/cnt/2014-06/109581/ecallinfo_png.jpghttp://www.heero-pilot.eu/view/en/ecall.html

  5. M2M Communication M2M ? IoT • Overlap • Boundaries not exact • Specific areas existIoT: objects/things that may or may not be in M2M relationship with an ICT system.Example: Passive object (RFID), not able to communicate directly. M2M relationship ends with the scanner capable of reading the RFID.

  6. M2M Communication TelematicsTelecommunication + informatics(etym: Greek tele /remote/ + Greek matos /automaton/) Tracking (vehicle, trailer, container) Fleet management Satellite navigation http://en.wikipedia.org/wiki/Telematics M2M roots • Telemetry Telecommunication + measurements(etym: Greek tele /remote/ + Greek metron /measure/) • Meteorology • Energy providers • Rocketry • Space science http://en.wikipedia.org/wiki/Telemetry

  7. M2M Communication Constrained Devices (IETF): Low cost Low CPU Low memory Low data rate Low power (battery) Small size (less battery) Other constrains: Embedded inside sg. or hostile/secure env. Lifetime ICT device < car < house Device characteristics • Multitude • several magnitude more M2M than Human2Device • Scalability? (#devices, NW load, data usage & pattern) • Variety/diverse requirements • computing/communication cap. • Invisibility • No human control. Mngmt? • Criticality • Life savers (eHealth, electricity) • Intrusiveness • Privacy

  14. M2M Communication Network misalignment • Current stage of M2M deployments is mainly wireless/cellular network. Advantages of using cellular: • “built-in features” authentication / security / (tracking) • In some cases mobility • Misalignment: Currently used NWs are optimized for different requirements. • Not designed for that many devices. • Most (~90%) deployed devices are stationary, do not require roaming capability or location tracking (which is cumbersome and waste radio resources and power). • Not designed for that kind of usage/traffic. Small amounts (nx100B) of data, enormous control overhead (handshakes for radio access / authentication / security / IP address / QoS params / …; data bearer establishment and teardown 20+ handshakes + TCP handshakes) • In some cases (Smart Grid) latency < 10ms [1] p.8., p.14-15.,

  16. M2M Communication oneM2M • Global partnership of telecommunication standards organizations (formed 2012) • “February 4, 2015: The era of widespread deployment of Machine-to-Machine (M2M) technology and the foundation for the Internet of Things (IoT) advanced significantly today when oneM2M, the global standards initiative for M2M and the IoT, issued its Release 1 global standards.” • http://www.onem2m.org/news-events/news/53-the-rise-of-the-machines-world-s-first-global-standards-for-m2m-deployment http://www.onem2m.org/technical/published-documents
