无线Mesh网络组播差错控制协议性能分析

摘要

从理论上对典型的无线Mesh网络组播差错控制协议BLBP、LBLBP以及HLBLBP的性能进行分析,通过MATLAB对各协议在不同丢包率情况下的重传次数、信道占用时间及端到端平均时延等性能进行实验仿真.研究结果表明:HLBLBP的整体性能最优,但其未考虑某些信道质量较差的节点对整个网络性能的影响.%This paper analyzed the performance of the typical multicast error control protocols in Wireless Mesh Networks from the theory,such as BLBP,LBLBP and HLBLBP.Then it simulated the performance of the number of retransmission,channel holding time and average end-to-end delay in different packet loss rates in MATLAB.The results showed that the performance of HLBLBP is better than others.But it does not consider that the poor quality nodes affect the performance of the overall networks.
