多接口多信道WMN中的AODV扩展研究

Research of AODV Extension for Multi-interface Multi-channel WMN

扩展仿真工具NS2以适应多接口多信道,研究并给出将无线网状网(WMN)中Ad hoc按需距离矢量路由(AODV)协议扩展成多接口多信道路由协议的方法和关键技术,给出在NS2中信道利用率的计算方法和适用于WMN的功率控制方法。仿真实验结果表明,扩展后的AODV能使多接口多信道WMN网络具有较高的吞吐量、信道利用率、投递率和较低的路由开销,提高网络性能。

It is necessary to research new routing protocols for Multi-interface Multi-channel（MIMC） Wireless Mesh Network（WMN）,but the NS2 simulator is no longer adapted to the MIMC simulate environment.The paper takes MIMC-AODV for example to introduce the key points of its extension procedures.A new evaluation parameter-channel utilization,power control methods for WMN and a power control method are proposed for WMN.Experiment is done under one scene especially for the WMN
