Consider an ARQ algorithm running over 2-Mbps point-to-point link to a stationary satellite orbiting around the earth at an altitude of 4 x 104 km. Assume that the speed of light is 3 X 108 m/s and that each frame carries 2 KB (kilobyte) of data. What is the minimum number of bits you need for the sequence number for the following cases? i. RWS = 1 ii. RWS = SWS
