A telephone modem is used to connect a personal computer to a host computer. The speed of the modem is 56 kbps, the one-way propagation delay is 100 ms, the packet size is 256 bytes, and the probability of an error in a packet is 10^-4. Find the efficiency of stop-and-wait ARQ. What window size N is needed to keep the channel busy when there are no transmission errors. For this window size finds the efficiency of the go-back-N and selective repeat protocols.
