一种新的IEEE80.11DCF有限负载性能分析模型
Novel model for IEEE80.11 DCF performance analysis on unsaturated traffic
摘要
Abstract
A performance model based on closed queuing network is established to evaluate the performance of IEEE 802.11 MAC based on the Distributed Coordination Function (DCF) under the condition of unsaturated traffic, which utilizes carrier sense multiple access with collision avoidance(CSMA/CA). The principle of operation and the applicability of the queue networks model is described. The impact of both the number of terminals, traffic load and package size on the performance are analyzed. The expression of throughput and transmission probability under unsaturated traffic load is derived by employing the queuing model. Simulation results show that the model can evaluate the performance of DCF effectively.关键词
