摘要：In this paper, we study the performance of the classical SW-ARQ, multichannel SW-ARQ and GBN-ARQ in discrete-time Geom./G/1 queue with setup mechanism. Based on the method of embedded Markov chain, the expressions of the packet average waiting delay, system average delay and channel utilization are respectively obtained. Finally, by numerical examples, we analyze the influences of packet length, the successful transmission probability and packet arrival rate on system average delay. The numerical simulation results show that the system delay could be lower by choosing an appropriate ARQ protocol.
