New areas for Networking
Internet of ThingsCheap
Moore’s law reduces costs, does not increase power
Low MemoryLow EnergyDifferent Time cycle
Legacy devices20 year lifetime

IPv6
IPv6 slowly introduced P6≠P4, A6≠A4: No interoperabilityMetcalfe’s law against IPv6Forwarding is not the most difficult part
IPv6 has advantages for IoTAuto-configurationSimplerLayer 2 agnostic
But difficult to make IPv6 evolveGeneva, Switzerland, 18 February 2014 9

One of the challenges: IPv6Mesh network.Minimize code footprint, minimize energy consumption.

Reduce 6LoWPAN impact
Toward a flexible 6LoWPANSimplify addresses allocation
A6LP ⊂ AIPv6
Forwarding based on 6LoWPANAdd functionalities for WSN
P6LP ⊃ PIPv6
Maintain end to end capabilitiesNeed for “local” informationIPv6 remains universal format

Conclusions and Recommendations
New constraints: A single protocol cannot cover all needsIntroduce more flexibility
“a la IEEE” Core protocols/Fringe protocols
Other alternatives:REST, but less generic in term of traffic
