Internet

End to end principle:

• Gateway are invisible to application

• Naming is uniform

L2 independence:

• Evolution, universality

• Abstract L2 characteristics

Cost reduction:

• Interconnection

• services deployment

• Management:• Objects

• Networks

Durability

Internet has been designed over an unlimited bandwidth model.

Node-G

• Manage nodes:– CoAP messages:

• Small, lightweight protocol

• Network parameters abstracted through resources[1]

– Beacon

– Authentication and encryption through standard protocols [2]

• Shared key, SIM card, Certificate,…

• Store messages– Sleeping nodes

Réseau Fabian

• Subset of Acklio technologies

– Proof of concept

– Open, simple to use, easy to understand• Prototyping new applications

– Testbed for smart city applications• Pollution or Energy monitoring

• City events

Conclusion

• LP-WAN is a IoT enabler

– Radio communication cost reduction

• Internet is a service enabler

– Scalable, secure and resilient infrastructure,

– 18 000 000 developers

• Ongoing standardization effort to merge these two technologies.
