QUEUING ANALYSIS OF THE SELECTIVE REPEAT AUTOMATIC REPEAT REQUEST PROTOCOL WIRELESS PACKET NETWORKS

This paper presents an analytical approach for analyzing the mean pack et delay and mean queue length at the transmitting terminal in wireles s packet networks using the selective repeat (SR) automatic repeat req uest (ARQ) scheme to control the errors introduced by the nonstationar y transmission channel. Each transmitting terminal is modeled as a dis crete time queue with an infinite buffer. The nonstationary transmissi on channel is modeled as a two-state Markov chain. Comparisons of nume rical predictions and simulation results are presented to highlight th e accuracy of the proposed analytical approach.
