摘要

针对无线Mesh网现有媒体访问控制(MAC)层协议在多跳多播方面缺乏可靠性保障且效率较低的问题

在无线局域网MAC层的信标帧驱动协议(BLBP)的基础上

提出了一种基于BLBP的无线Mesh网MAC层多播协议(Layer-BLBP).按照每一跳将一次多播分成若干层

每一子层有一个Leader来完成确认帧的反馈

Layer-BLBP利用出错帧/确认帧的反馈及碰撞来保障多播的可靠性

通过分层协调方法来提高多播的效率.理论分析和仿真实验结果表明:Layer-BLBP 在无线Mesh网下可使多跳多播可靠完成

在节点差错率大于10%的情况下

比BLBP和原有MAC层协议的传输性能提高了10%以上.

Abstract

Aimed at the problem that the existing media access control(MAC)protocols for multihop multicast in the wireless mesh networks(WMNs)are lack of reliability and efficiency

a layer-divided beacon-driven leader based protocol(Layer-BLBP)is proposed based on the wireless local area networks MAC-Layer beacon-driven leader based protocol(BLBP). One single round multicasting is divided into some sub-layers by each hop

and a leader is selected in each sub-layer. The Layer-BLBP uses acknowledge frames and non-acknowledge frames feedback and collision to ensure reliability of multicasting

and adopts sub-layer coordination to enhance the performance. Theoretical analysis and simulation results show that Layer-BLBP is reliable for multihop multicast in WMNs. Comparisons with BLBP and other existing MAC-Layer protocols show that the efficiency of the Layer-BLBP is increased by at least 10% when the node error rate is beyond 10%.
