Q1. Stations A and B are using Go-Back-N ARQ protocol to communicate where window size is N. The station A has infinite supply of frames to send to B and B is acknowledging them according to the protocol. Assume that probability of a frame error is ; and ACK error is . Now assume that communication began now and station A has sent its first frame to B. Station B has received this frame error free and sent an ACK to A but ACK was lost in the channel. Determine probability that A will still make the decision that this frame has been received by B error free and therefore it willnot retransmit this frame
