I am doing routing experiment with two USRPs and tunnel.py. Machine A
keeps
sending, and another machine B forwards the message when it receives
from
A. Before B forwards message, it calls tb.carrier_sensed() to do
exponential back-off. But I have never see the carrier_sensed() works.
If
it works, it should print ‘B’ and doesn’t send when machine A is
sending.
In reality, machine B lost a lot of messages from A, which are supposed
to
be received with carrier_sensed().
Apparently you did not set the threshold correctly. Measure the
transmitting power in dB firstly and then adjust the threshold.
btw, are you doing the routing experiment with only two USRPs?
