摘要:

基于距离向量的按需路由协议AODV是Ad Hoc网络研究的热点之一。本文针对AODV路由协议提出一种链路可用时间算法,在路由请求数据包中增加链路可用时间参数,路由应答数据包中增加路径可用时间参数,路由维护阶段提出预先维护的思想,保证数据的稳定传输。NS2平台仿真表明,改进后的AODV协议使路由的可靠性得到改进,提高了分组的投递率,降低了端到端平均传输时延。

Abstract:

Ondemand distance vector routing protocol AODV is one of the research hotspots in Ad hoc Networks. To ensure stable data transmission, a link available time algorithm of AODV is proposed, which increases a parameter of link available time in the route request packet and a parameter of routing path available time in the route reply packet. In the process of routing maintenance, intermediate nodes start the repair process before the link really fails. Compared with the traditional algorithm, the results obtained in NS2 simulation platform show that the improved AODV protocol enhances the reliability of the routing, improves packet delivery ratio and reduces the average endtoend transmission delay.
