| 摘 要： | MAC层吞吐量分析是无线Ad hoc网络容量分析的基础。对CSMA协议特别是IEEE802.11DCF协议建立了一个Markov链分析模型。分析得出状态间的转移概率,通过建立状态方程得出稳态概率的线性方程。通过数值方法得出稳态解,从而得到无线Ad hoc网络MAC层吞吐量,并与公认的网络容量分析结果做了比较。通过吞吐量与节点数及分组大小的关系曲线,为网络性能的优化提供了理论基础。

| Abstract: | The analysis of MAC layer's throughput is the basis of the analysis of capacity of wireless ad hoc networks.An analysis model of Markov chain for CSMA protocol with RTS/CTS is designed.The channel is modeled by a five states Markov chain,which can be used to analyze properly the performance of the MAC protocol.After deriving transition probability,the state equations are established.Then stability probabilities are obtained,and then the throughput is gotten.The analysis in this paper is the cornerstone of t... |
