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 nodes implement an IDS to detect attacks coming from the network.
