Internet-of-Things
• IoT is everywhere…
• Wearable devices (smart person)
• Smart home / smart building
• Smart city
• Smart… country?

Internet-of-Things
• Requirements on the network platform?• Global reachability
• Reach every node without going into the application layer
• Mobility• Things tend to have different levels
of mobility
• Fitbits, smart vehicles, drones, …
• Richer communication patterns• Serve requests
• Node to node communication
• Multicast and anycast support
• Resource heterogeneity• Computation (CPU frequency < 100MHz | i5 cores)
• Storage (RAM < 50kB | > 4GB)
• Transport (MTU < 128 bytes | > 1500 bytes)
• Power (Button cells | power plugged)

Internet-of-Things
• Requirements on the network platform?• Low latency, and lower…
• Several seconds delay for applications like alarms, intrusion detection, …
• < 5ms delay for applications like VR/AR
• Scalability• Support more devices
• Support queries to be disseminated and response collected in a scalable way
• Get the average engine temperature of all BMW cars in New Jersey
• Service-oriented communication• Reach the road-side unit 5 miles ahead of me
• Control the environment around me
• Surveillance camera → object recognition → notify me if my missing pet appears
• Security• IoT is going to collect sensitive data
• Protect the privacy

ICN Architecture
• Unique names as the routing labels
• Late-binding, store and forward
• Multicast, anycast support based on names
• Self-certifying contents
• Content-oriented encryption
