The Zephyr IP mesh networking implementation is based on RPL, which is a routing protocol for low powered and lossy network (LLNs). LLNs are a class of network in which both the routers and their interconnect are constrained. LLN routers typically operate with constraints on processing power, memory and energy (battery power). LLN links have high loss rate, low data rates and instability.
This presentation details how to make use of Zephyr networking to utilize multiple interfaces (Ethernet and 802.15.4) and form a mesh network and control leaf nodes in the network. An 802.15.4 interface forms an RPL mesh network and Ethernet interface provides a web interface that shows and controls the mesh network leaf nodes. The web interface also displays the topology of the mesh network. Technologies involved here are Ethernet and 802.15.4, 6lowpan, IPv4/6, RPL, TCP, UDP, HTTP, Websocket and CoAP.
