In this paper, we evaluate the performance of TCP-over-Selective Repeat (SR) ARQ in wireless fading channels. We show that fading speed has great impact on buffer requirement in order to acquire high end-to-end throughput. In addition, TCP end-to-end throughput will degrade due to ARQ's transmission window stalling if wireless propagation delay is so large as not to be ignored. Two advanced SR-ARQ schemes derived from normal SR-ARQ, called Linear-SR and Expo-SR, are studied. Simulation results show that they can greatly improve TCP performance.
