Abstract

One of the attractive features of the wireless mesh network is its ability to scale to larger covered area by simply adding more wireless routers. This scalability increases the average number of hops from source to destination and hence it may affect the network performance in terms of delay and throughput. Many solutions have been proposed for wireless mesh networks. Among them the 802.11s proposes a Hybrid Wireless mesh Protocol HWMP. This protocol combines the functionalities of the Radio Metric Ad-hoc On demand Distance Vector protocol RM-AODV and the Tree Based Routing protocol TBR. In this work we propose to evaluate the scalability of the HWMP using network simulator NS2. For this purpose we used a grid wide network topologies with n*n static Mesh Point MP routers. The simulation results show a very interesting result related to the loss rate, path establishment delay, network throughput and signaling overhead.

无线网状网络802.11s中混合协议的可扩展性
无线网状网络的一个吸引人的特点是它能够通过简单地添加更多的无线路由器来扩展到更大的覆盖区域。这种可伸缩性增加了从源到目的地的平均跳数,因此可能会影响网络性能,包括延迟和吞吐量。针对无线网状网络,已经提出了许多解决方案。其中,802.11s提出了一种混合无线网格协议HWMP。该协议结合了无线电度量自组织随需应变距离矢量协议RM-AODV和基于树的路由协议TBR的功能。在这项工作中,我们建议使用网络模拟器NS2来评估HWMP的可扩展性。为此,我们使用了一个带有n*n个静态Mesh Point MP路由器的网格网络拓扑结构。仿真结果显示了丢包率、路径建立延迟、网络吞吐量和信令开销等方面的有趣结果。
