This is an example of bursts support in CSMA/ContikiMAC, together with storage of long packet queue in CFS. This is useful to support large fragmented UDP datagrams or continuous data streaming. The current implementation is a simplified version of the techniques presented in "Lossy Links, Low Power, High Throughput", published in the proceeding of ACM SenSys 2011. In this example, node with ID==5 sends bursts of UDP datagrams to node with ID==1, the root of the RPL dodag. Testing in cooja: $make TARGET=cooja udp-stream.csc Testing on Tmote sky: 1) set node IDs to different motes so node 5 sends to node 1 (using examples/sky-shell) 2) compile and program: $make TARGET=sky udp-stream.upload 3) monitor motes with: $make login MOTE=xxx
