Summary:
In this paper, we propose a simple analysis model for the transport delay of the negative acknowledgment (NAK)-based selective repeat automatic repeat request (SR-ARQ). We define the transport delay as the time from a packet's first transmission until its successful arrival at the receiver. By analyzing the transport delay, we can evaluate the efficiency of SR-ARQ's loss recovery procedures as well as its delay performance. Particularly, the model considers the traffic condition and a finite retransmission persistence of SR-ARQ as well as the packet loss rate over a wireless link. Finally, the analysis model's accuracy is verified by the simulation results.
