为适应无线网络拓扑结构的动态变化和无线信道的不稳定性,针对三层路由的Qo S较大受限于网络拓扑结构变化的缺陷与不足,研究并实现了一种无线网络二层交换路由协议算法。算法主要研究按需路由策略,针对无线网络特点介绍了路由表设计原则,进一步给出了路由表以及按需路由报文格式、按需路由流程与二层路由转发流程及其实现,并通过实验对比对协议进行性能分析。实验结果表明,该算法有效降低了动态拓扑的无线网络路由建立时间。

In order to adapt to the dynamic changes of the wireless network topology and the instability of the wireless channel,in view of the defects and shortcomings that the QoS of layer3routing is greatly limited by the change of network topology,a wireless network layer2switching routing protocol algorithms is analyzed and implemented.The on-demand routing strategy for the algorithm is discussed.The design principle of routing table is described in view of the characteristics of wireless network.In addition,the routing table,the message format of on-demand route,the on-demand routing process,layer2routing forwarding process and its implementation are given.The performance of the protocol is analyzed by experimental comparison.The experimental results indicate that the algorithm can effectively reduce the routing establishment time of wireless network in dynamic topology.
