【摘要】 对AODV中的链路建立及修复问题进行了分析,提出了优化方案.通过Hello报文及侦听相邻节点路由信息,构建直接邻接节点和二跳相邻节点集合,用矩阵来描述和处理直接邻居的连接,以辅助完成路由查找和修复的任务.通过模拟试验发现,与传统方法相比,该方案可以减少因链路断裂带来的时延,在一定程度上减少了路由开销.更多还原

【Abstract】 The link set-up process of AODV was analyzed and a way to fix the break links was presented,through building neighboring node sets and local link set(described with matrix) by overhearing the messages within nodes′signal reception range.The method can be used to support the search and repair of the routing tasks without sending extra messages.The simulations showed that this method can reduce the trans-delay caused by broken links,thus reduce the routing overhead to a certain extent compared with traditonal methods.更多还原
