IoT(Internet of Things)

Everything that can be connected will be connected

Adapt the Internet to different types of networks such as constrained

networks/nodes, e.g. send temperature in a 802.15.4 packet

Constraints Networks:

o low achievable bit rate/throughput

o high packet loss and high variability of packet

o highly asymmetric link characteristics,

o limits on reachability over time

Constrained Nodes:

o Limits on power

o Memory

o Processing

resources

IPv6 over Networks of Resource-constrained Nodes (6Lo) WG

aims to extend 6LoWPAN to different technologies

- RFC 7428: Transmission of IPv6 Packets over ITU-T G.9959 Networks

- RFC 7668: IPv6 over BLUETOOTH(R) Low Energy

− IPv6 over Bluetooth Low Energy Mesh Networks● draft-ietf-6lo-blemesh-01
