摘要
针对无线传感器网络的特点,在LEACH协议的基础上,提出一种新的能量优化分簇路由算法。该算法使用能量因子修正了LEACH协议中的阈值,产生簇头;再选取距离最近的两个节点形成节点对,选择能量高的节点采集发送数据,采集的数据最后通过簇头融合提交给基站,从而减少了节点的能量消耗。MTLAB仿真结果显示该协议有效延长网络的稳定期。
According to the characteristics of the wireless sensor network,in the research on the basis of LEACH,this paper puts forward a new routing protocol based on the energy optimization clustering.The algorithm using energy factor fixed in the threshold value of LEACH,produce the cluster head.Then choose the closest two nodes to form node group,high energy of the node to send data collection.Final data fusion in cluster head was submitted to the base station,reduce the node energy consumption.MTLAB simulation shows that,the improved protocol has the results of effective prolonging the stable time of network.
