摘要
Ad Hoc网络是一种自创造、自组织和自管理的网络,开发良好的路由协议是建立Ad Hoc网络的首要问题.AODV协议是Ad Hoc网络中最具代表性的按需路由协议之一.文中详细分析了AODV的局部修复机制,并在此基础上,讨论了两种典型的改进思想.提出了一种优化算法OPTAORTI,该算法通过对局部修复机制的改进在保证相对少的增加路由开销的同时降低路由延迟.模拟结果表明该算法的路由延迟低于原协议及两个改进算法.
Ad Hoc is one sort of self creation, self-organization and self supervision network in which a favorable routing protocol is very essential . AODV is one of the most representative protocols of Ad Hoc network. Local repair mechanism of AODV is analyzed and two kinds of modified mechanism are presented. An optimized routing mechanism is proposed which will reduce the delay with comparatively small increasing the overload time. Simulation results show that the delay by this algorithm is lower than AODV and two modified mechanism.
