Network (IP)

— To support multi-RATs, parallel IoT networks need to be deployed — Drives up costs — Not scalable

Fragmentation over protocol stacks

PHY MAC Wireless Mesh Transport Platform APP Transceiver domain More than 40 existing protocols (RATs) e.g. Zigbee, BLE, WiFi, NB-IoT, LoRa etc. IPv4, IPv6, non-IP proprietary CoAP, MQTT, HTTP … Application domain: vertical and horizontal, semantics (IPSO, Zigbee Alliance, OMA LWM2M, UPnP Forum etc.)

Current GW approach More fragmented here! Cloud platform approach

— Reference approaches: single RAT — WiFi AP-AC approach: real time function in AP and non-real time function in AC. — Cellular C-RAN/V-RAN approach: centralize processing for performance, cloudify high layers for scalability and cost reduction — Extend such approaches for Multi-RAT IoT: IoT Cloud RAN at Edge — Radio infrastructure: IoT radio heads handling multiple IoT radios, e.g. BLE, Zigbee, NB-IoT, LoRa etc. — Edge Cloud: virtualized full-stack IoT multi-RAT functions, i.e. PHY, MAC, NET …, in an Edge Cloud environment

— Full stack implementation — PHY: GNU Radio — MAC and higher: Contiki-NG — Early integration: UDP socket — Virtualization: Docker — Radio head: SDR-based — FH interface: IQ samples over Ethernet (currently ZeroMQ) — Challenges: — Decrease latency — Decrease jitter

PoCdesign example: IEEE 802.15.4

Wifi 802.15.4(e) PLC Bluetooth IPv6 (+ 6LoWPAN) + RPL TCP UDP HTTP MQTT .. CoAP .. .. CoAP + DTLS + LWM2M + IPSO objects

— EUCNC demo: first functional-level software implementation and system integration, 15.4 full stack and NB-IoT DL (key PHY functions) dockerized at edge — Next step: more measurements and results analysis, and then further improve the implementations, e.g. in radio performance, reliability, latency etc.
