| 摘 要： | 针对传感器网络中的节点能源有限的特点，文章在分析LEACH的基础上，提出一种高能效的路由算法。该算法根据各节点剩余能量大小和簇成员数控制簇的形成，使簇头之间通过多跳合作的方式与基站进行通信，从而使网络能量均匀消耗。仿真结果显示，与原LEACH协议相比，改进后的算法提供了更长的网络生存时间。

| Abstract: | The nodes have limited available power in wireless sensor networks. In view of the trait, this paper analyzes leach protocols, and an energy-efficient routing algorithm is proposed and evaluated in which the cluster formation is controlled by the residual energy and the number of cluster members. In addition, the cluster heads take hierarchical routing scheme to communicate with the base station. Simulations show that the new algorithm provides longer lifetime than leach protocols. |
