+UDP stream
+==========
+
+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:

+Testing on Tmote sky:

+1. Set node IDs to different motes so node 5 sends to node 1 (using
