why the bandwidth becomes very low after a period of simulation？ #234

In the case of weak signal(SINR is approximately 30), after running for a period of time, the bandwidth will suddenly be close to zero, and it's can't recovery. This length of the time(3s, 12s, 34s, 47s ...) is affected by the buffer, congestion control protocol, application and many other aspects. Why does this happen? After my test, I found that the lost packet was repeatedly resent.

Hi,

could you please provide more details, for instance which example you are trying to run?

Best, Matteo
