基于AODV协议的无线传感器网络多路径路由改进机制

An Improved Mechanism of Wireless Network Multi-path Routing Based on AODV Protocol

首先分析了AODV协议在静态无线传感器网络中的传输过程,接着针对单路径路由机制存在的中间节点路由延迟较大、负载集中而导致的网络节点能耗不均、数据传输效率低的问题,提出了一种针对AODV协议的改进方案。此改进方案在AODV协议中引入了多路径路由机制,同时在路径选择时考虑了节点剩余能量,从而在无线传感器网络数据传输中能避免热点,较好地解决了断链问题,同时也减少了原AODV路由查找的次数和延时,降低了路由开销。

This paper analyzes the transmission of the AODV protocol in the static wireless sensor network.With regard to the problem of high energy consumption of network nodes and low efficiency of data transmission as a result of the large routing delay and load concentration of the intermediate nodes in the single-path routing mechanism,this paper proposes an improvement program on AODV protocol.This improvement program introduces multi-path routing mechanism in the AODV protocol and takes into account the residual energy,which avoids hot spots in the data transmission of wireless sensor networks,solves chain scission better,reduces times of the original AODV route in lookup and delay and reduces the routing overhead spending.
