Apologies if this has been addressed previously:

Currently I am running a simple application to measure the throughput of the 
default Telos-A MAC.  I have one mote send messages as fast as it can (i.e. it 
sends a new message as soon as SendDone is signalled) and another mote keeps a 
running count of all of the messages that it hears.  In addition, each message 
has a sequence number so the listener can tell if a message was missed.  When I 
run this experiment, I consistantly see that (roughly) only 85% of the sent 
messages are received by the listener.  If I change the sender to send a little 
more slowly, the reception rate quickly goes up to 100%, so its definitely the 
speed-of-sending that is causing the ~15% loss rate.

Is this known behavior?  What causes it?  Does the listener take longer to 
"reset" it radio somehow, as compared to the sender?

Thank you very much,
Ian Rose
