Hello Everyone,
We are trying to simulate some routing layer protocols. But we found that
MAC layer is not working as expected. There are a lot of packet drops. The
noise power is kept low ~ -100dbm. Still, there are 4-5 packet drops out of
10 when we have two transmitter transmiting at different
Hi,
can anyone please tell me how to turn ON debug statements of system files ?
I am able to track debug statements from my application but not from source
files. Basically i wish to track statements like :
dbg(CpmModelC,SNRLoss, - lost packet from %i as SNR was too low.\n,
(int)mine-source);
CAn anyone reply please ? :)
