| 摘 要： | 针对无线传感器网络节能问题,详细分析了经典分簇协议——LEACH,在其基础上针对LEACH的不足进行改进,提出了一种能量高效的分簇路由协议。该协议在簇头选举的算法中纳入节点剩余能量作为参数,提出各簇独立进行的簇头轮换机制,控制簇头在簇中的分布和各簇成员节点数目,并采用基于阈值的单跳与多跳相结合的簇间通信方式。仿真结果表明,改进后的协议较LEACH能够有效节约节点能量,均衡网络各节点消耗,显著延长了网络生存周期。

| Abstract: | Aimed at the problems of saving-energy for wireless sensor network,the classical clustering LEACH protocol is analyzed,based on which an improved clustering protocol is proposed against deficiencies of LEACH.The residual energy is brought into electing cluster-head as a parameter in new protocol,and a new mechanism of the cluster heads independently by turns is advanced.In addition,it controls the distributing of cluster heads and the number of cluster members in cluster,and sends data to the base station b... |
