摘要
针对DSR(Dynamic Source Routing)协议的路由维护在路由失效时并不能及时提供最佳预备路由这一问题,提出了一种优化的路由维护方案——在数据分组头部增加两个域以记录源节点和下一跳断开节点之间(包括源节点和下一跳断开节点)哪个节点缓存有到目的节点的最佳预备路由。仿真结果表明,新的路由维护方案显著地降低了分组的平均端到端延时并增加了分组投递率。
Route maintenance of DSR protocol can not provide best alternate route at the time of route failures.This paper presents an optimization scheme to enhance route maintenance part of DSR protocol.Two fields are added in packet header to find out which node in between source node and the node whose next hop is unreachable(including both source node and the node whose next hop is unreachable) has best alternate route to destination.Simulations results show that the new route maintenance reduces average end-to-e...
