In this paper, considering the data packet arrival rate, channel transmission quality under the influence of cooperative, the working principle of SW-ARQ protocol, offered to take vacation Geom \ G \1 Queueing model. Research of wireless communication system, collaborative SW-ARQ retransmission mechanism, analyzed the mechanism in discrete time delay under the performance index, gives the system average waiting time, average system delay, system throughput analytical expression. Using MATLAB simulation analysis of transmission error rate, packet arrival rate on the system delay, throughput, utilization efficiency, results show the performance index formula is correct.
Keywords: cooperative principle expression throughput index |
