I have a doubt regarding the time a particular node will wait after collision.
I am using numerical values here so that one can easily understand my doubt.
Suppose in a network, we have 2 nodes A and B with propagation delay of 225 bit times.
If A and B sense channel at the same time and find it idle, they both will collide and will sense collision at 225 bit times .
If we assume jamming signal as 48 bit and IFS time 96 bit time(standard ones), then both A and B will send jamming signal to all other nodes by 225 + 48 = 273 bit time.
Now I want to know whether channel is really idle by time 273 bit times and can A start sending after IFS time or the channel still contains B's transmission and A needs to wait for another 225 bit times (propagation delay) until B's last bit reaches A and channel is cleared?
