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 relatively mature and widely accepted mobile ad hoc network routing protocol, which is relatively simple to implement. However, when the network topology changes rapidly, this protocol will generate a large amount of control information and increase the protocol overhead of the network, causing the network bandwidth As resource and energy resource consumption increases, other performance of the network will also be affected. In this paper, we improve the traditional AODV routing protocol by optimizing the Hello message and cooperating with the MAC layer, and propose an improved AODV routing algorithm: MAC-AODV routing algorithm. The simulation shows that MAC-AODV routing algorithm reduces the protocol overhead and improves the network performance compared with the traditional AODV routing algorithm.
