摘　　要：提出了一个基于AODV协议的动态路由管理算法,通过算法动态地配置路由协议参数,适应网络环境的变化,提高路由协议性能.算法利用模糊逻辑对移动自组网(MANET)网络环境进行分类,根据不同类型的MANET网络环境选择不同的AODV路由参数来改善路由性能.将这种算法应用到AODV路由协议中,通过NS2网络仿真器对标准AODV算法和基于AODV的动态路由管理算法进行了仿真比较.仿真结果表明,基于AODV的动态路由管理算法显著改善了协议路由性能.这证明在优化MANET路由性能研究领域中应用模糊逻辑的可行性.A dynamic routing management algorithm based on AODV protocol was proposed, to which the required different protocol parameters could dynamically be allocated so as to adapt it to the changing network contexts and improve its muting performance. Taking advantage of fuzzy logic, the MANET network contexts were classified in the algorithm and the different AODV muting parameters to be selected according to different network contexts for improving the routing performance. The algorithm was applied to AODV protocol and simulated by NS2 to compare its performance with standard AODV protocol. The simulation results showed that the algorithm can improve significantly the routing performance and that the application of fuzzy logic is available to optimizing the muting performance of MANET.
