You aren't setting up RF noise. So nodes never get a clear channel.

hello,
I am new to the TOSSIM simulation. I ran the MultihopOscilloscope
application in TOSSIM. The application seems to be working fine in
delivering the sensor data to the basestation, however, I have
noticed that many sensor data never get sent due to the fact that a
mote cannot send if a .SendDone event has not been signaled after a
a .send command.
I have used the exact same code provided with the original
application. I would really appreciate it if some body can explain
to me why is it taking a very long time for a mote to receive
a .SendDone event, as such behavior seem to be resulting in a great
loss rate. A sample run is attached.
THANKS SO MUCH
