中文摘要：
无线Mesh网络中，链路的动态性和链路流内、流间干扰极大影响路由协议的性能.针对此问题，文中提出路由判据EPBW，该判据充分考虑链路多速率以及负载的动态性以准确评估链路的可用状态；然后，基于EPBW，为最大化网络吞吐量，文中提出了分布式路由协议EPBWR.最后，在NS-2中实现了文中判据与协议算法，并且在多种网络环境下进行仿真，与其它协议进行对比，评估协议性能.仿真结果表明：文中路由判据EPBW能适应网络的动态性，具有较高吞吐量，并且协议性能优于AODV、DSDV与DSR等协议.
英文摘要：
The dynamic link load and inter- and intra-flow interference in the wireless mesh net- work greatly affect the performance of the routing protocol. To solve this problem, firstly, we put forward a routing metric, EPBW, which gives full consideration to the multi-rate link and dynamic link load in order to assess link availability status accurately. Secondly, based on EPBW, we propose a distributed routing protocol, EPBWR, to maximize the network throughput. Finally, we implement the metric and protocol in NS-2, and also simulate it under multiple net-work scenarios to evaluate the protocol performance by comparing with other protocols. The simulation results show that the proposed EPBW can adapt to the dynamics of the networks with higher throughput, and outperforms other protocols including AODV, DSDV and DSR.
