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

• 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.
