摘要
AODV是一个比较成熟并被广泛接受的移动自组织网络路由协议,实现起来比较简单,但在网络拓扑快速变化时,采用此协议会产生大量的控制信息,增加网络的协议开销,从而引起网络带宽资源和能量资源消耗的增加,网络的其他性能也将受到影响。文中通过优化Hello消息并与MAC层合作对传统的AODV路由协议进行了改进,提出了一种改进后的AODV路由算法:MAC-AODV路由算法。仿真表明MAC-AODV路由算法相对传统AODV路由算法减少了协议开销,提高了网络性能。
AODV is a comparatively mature and widely accepted routing protocol. It is relatively simple to implement, but rapid changes in the network topology would bring lots of control information and increase protocol overhead, and thus consume more bandwidth and energy resources,and other performance of networks would be impaired.This paper, by making use of hello message and cooperation of MAC sub-layer, brings up an improved AODV: MAC-AODV. Simulation indicates that, compared with the traditional AODV, it reduces the protocol overhead and improves the quality of Ad Hoc network.
