Two stations (A and B) are on the same broadcast domain approximately 200 meters apart. Suppose A and B transmit 1500 bytes at the same exact time and their frames collide. A chooses K = 0 and B chooses K = 1 in the exponential backo protocol. Assume the transmission speed is 10 Mbps, the channel is CSMA/CD with backo intervals that are multiples of 50 s, the jam signal takes 10 micro sec to transmit. c = 2.0 x 10^8 m/s (a) What is the one-way propagation delay between A and B? (b) At what point in time is A's packet delivered to B?
