M2M ? IoT

Overlap Boundaries not exact Specific areas exist

IoT: 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.

M2M roots

Telemetry Telecommunication + measurements(etym: Greek tele /remote/ + Greek metron /measure/)

Meteorology Energy providers Rocketry Space science

Telematics Telecommunication + informatics(etym: Greek tele /remote/ + Greek matos /automaton/)

Tracking (vehicle, trailer, container)

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

Constrained Devices (IETF): Low cost Low CPU Low memory Low data rate Low power (battery) Small size (less battery)

Other constrains: Embedded

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.,
