| 摘 要： | 针对无线Mesh网现有媒体访问控制层协议进行多播时效率较低的问题,在分层信标驱动的无线Mesh网多播差错控制协议(Layer-BLBP)的基础上,提出了一种面向前向纠错的无线Mesh网多播差错控制协议———混合分层信标帧驱动协议(HLBLBP).该协议通过引入前向纠错技术和减少多播纠错时控制帧数量来降低重传次数,从而提高了用于数据传输的实际开销占整个多播过程的时间比例.仿真实验结果表明,新协议有效提高了多播网络的总体性能,提供的实际吞吐率比Layer-BLBP提高了25%以上.

| Abstract: | A hybrid-layer-divided beacon-driven leader based protocol(hybrid-layer-BLBP,HLBLBP) is proposed on the basis of forward error correction(FEC) to deal with the problem that the existing media access control(MAC) protocols in wireless mesh networks(WMNs) are less efficient.The proposed protocol bases on the wireless local area MAC-Layer layer-divided beacon-driven leader based protocol(Layer-BLBP).Since the proposed protocol employs the FEC technology and reduces the number of the control frames for multicas... |
