To keep track of packet loses, it is possible to keep a packet
counter in your application which is incremented whenever a packet is
successfully sent. Then, add a debug statement in Receive.receive
that prints this counter when a packet is successfully received. You
will see only the counter values that were actually received.
You may need multiple counters as you have multiple links.
This approach is similar to what is done in the RadioCountToLeds
program in the /tinyos-2.x/apps/ directory.
