为了提高无线传感器网络的生存时间,针对当前LEACH算法存在的能量不均衡难题,提出一种能量均衡的无线传感器网络节点路由算法。首先将监测区域看成以基站为中心的扇形区域,并将扇形区域分割成不同大小的弧形方块,每个弧形方块中的节点组成一个簇,根据节点剩余能量产生簇头,然后采用单跳和多跳相结合的簇间通信机制,最后采用仿真实验测试算法的性能。结果表明,本文算法有效提高了网络的能量利用率,能够实现节点之间的能耗均衡,使无线传感器的网络生存时间得到延长,适用于对网络生命周期要求较高的应用。关键词:无线传感器网络;能量均衡;非均匀分簇;网络生存时间。

In order to prolong life of wireless sensor network, a novel clustering routing algorithm in wireless sen_sor networks based on energy equalization. Firstly, the monitoring region is divided into circular area which base sta_tion is taken as the center, and the monitoring area is divided into multi-sectors, the nodes in blocks form a cluster, and then the cluster head is selected according to the node residual energy, and the corresponding cluster communica_tion according to the dispersion coefficient of cluster head, finally, single hop and multi hop is used to communicate between and the simulation experiment to used to test performance of the algorithm. The results show that the proposed algorithm can effectively improve the network energy efficiency and achieve energy consumption balanced among nodes, so it can prolong life time of wireless sensor network, and consistent with the wireless sensor network energy-limited special conditions.
