Failure of following the submission instructions will have the derail mark deducted by 20%. Question 1: A new retransmission strategy WEIGHT = 4] Consider the sliding-window ARQ protocol. The sender always has frames to send. The receiver always sends an ACK when receiving a CRC-validated data frame. Let SWS -2 and RWS 1. Moreover, we introduce a new retransmission scheme to the sender. In this scheme, the sender will immediately send the oldest unacknowledged data frame if it receives an old ACK. An ACK is considered old if it has been received before or the value of the ACK is 0. Assume that this retransmission scheme always retransmits earlier than the case with timeout mechanism. (a) [WEIGHT 2] Draw a time-line diagram for the case where the first data frame (SN 0) has bit errors and is dropped by the receiver. All subsequent transmissions (data and ACKs) are assumed to be error-free. Draw the diagram until the receiver’s NFE is equal to 3. (b) [WEIGHT 2] Draw a time-line diagram for the case where the transmissions of the first data frame (SN 0) and its ACK are error-free, but the second data frame (SN 1) has bit errors and is dropped by the receiver. All subsequent transmissions (data and ACKs) are assumed to be error-free. Draw the diagram until the receiver’s NFE is equal to 3. Show transcribed image text
