能量高效的无线传感器网络AODV路由协议研究

Research on Energy-efficient AODV Routing Protocol for Wireless Sensor Networks

针对传统AODV路由协议在路由发现过程中采用洪泛机制会带来很大的通信开销这一问题,提出了一种基于路径深度的AODV路由协议,减少了参与路由发现过程的节点数,以减少通信开销。在节点转发路由请求时,引入一个时间延时,最大可能地选择最短路径实现通信。实验结果表明:改进的协议有效地减少了能量消耗,减少通信冲突。

According to the problem that traditional AODV routing protocol in routing discovery process used flood mechanism will bring great communication cost, a new kind of AODV routing protocol based on path depth is put forward. It reduces the number of nodes which devote into the routing discovery process. As a result, the cost for communication can be saved. Moreover, to introduce a time delay when the nodes forwarded node routing request is likely to choose the shortest path to realize communication. The experimental results show that： the improved protocol can effectively reduce energy consumption and communication conflict.
