Discussion: Layer 0 – The Network
§ Fragmentation needs to be resolved to fulfill the promise of the IoT!§ There will not be one protocol to rule them all!
- Power consumption & battery power - Environment of a deployment
§ Convergence to Internet Protocols- IPv6 (6loWPAN, TCP/UDP)
§ Consolidations will take place (and need to!):§ PAN: Zigbee 3.0 – Thread - Wi-Fi HaLo§ LPWAN: SigFox – 5G
§ Pick the simplest path:- ~10 years for routers to be rolled out

§ Other protocols can be translated to HTTP/WS - MQTT (quality of service, remote actuation) - CoAP (battery, low power)

§ Using Web protocols is the first step towards true interoperability - Helps “opening” devices, freeing them through APIs
§ Web protocols cover the “How” not the “What” - Great for humans, challenging for machines - Semantic Web, JSON-LD - First W3C proposal for the Semantic Web of Things:
