摘要
在无线传感器网络中,一种合理的路由算法对提高网络寿命有着非常重要的作用,基于传统的分簇路由协议LEACH,以延长网络寿命和提高网络通信质量提出了一种新的路由算法。这种路由算法引入了有向天线的使用。算法在定向传播的基础上不但节省了网络能量,并且灵活的簇群配置,簇头交换策略使得这个新的算法不局限于特定拓扑分布无线传感器网络。算法的创新点在于利用天线的方向形成簇群,同时达到了在数据传输时能量节省和网络路由变化通信开销减少的目的。
In wireless sensor networks (WSNs), a reasonable routing algorithm is very important for the life-span of the network. So, based on traditional LEACH algorithm in wireless sensor network, a new enhanced algorithm is proposed in the paper. This algorithm brings in the using of smart antenna, also, thanks to multiple configuration of cluster forming and reforming, it does not only achieve a better performance of energy efficiency but also provides flexible solution for wireless sensor network with different topologies.
