In the GO back N ARQ sender is sending the 20 packets to the destination with a window size of 4. Every sixth packet is lost and after a packet loss sender is sending one dummy packet outside the window for ensuring everything is correct [ dummy packet is an outside packet not the part of the window]. How many number of transmissions will be there?

How do you find the channel utilization with stop and wait protocol?
The distance from Earth to a distant planet is approximately $5 \times 10^9$ km. Assume that the frame size is 15 Kbits and the speed of light is $3\times 10^8$ m/s. Assume that the bit rate is 8 Mbps. What is the efficiency (channel utilization) if a stop-and-wait protocol is used?
