A simple RPL network with UDP communication. This is a self-contained example:
it includes a DAG root (udp-server.c) and DAG nodes (udp-clients.c).
This example runs without a border router -- this is a stand-alone RPL network.
The DAG root also acts as UDP server. The DAG nodes are UDP client. The clients send a UDP request periodically, that simply includes a counter as payload. When receiving a request, The server sends a response with the same counter back to the originator.
The .csc files show example networks in the Cooja simulator, for sky motes and
for cooja motes.
For this example a "renode" make target is available, to run a two node emulation in the Renode framework. For further instructions on installing and using Renode please refer to Contiki-NG wiki.
