摘要： 无线传感器网络的路由协议设计要同时关注单个节点的能耗及整个网络能量的均匀消耗。在分析现有分簇路由协议的基础上，提出一种能量高效的分簇路由协议，通过结合节点能量选举簇头，采用限制簇规模的优化簇形成算法和改进的多跳簇间转发方式，节约节点能量，平衡簇间负载。仿真结果表明，该协议能有效降低网络能量消耗，延长网络生存周期。

Abstract: Designing clustered routing protocol for Wireless Sensor Network(WSN) need consider the energy of single node and the balance of the whole network energy consumption of. On the basis of analyzing the characteristics and shortcomings of clustered routing protocols, this paper proposes an energy-efficient clustered routing protocol. It considers the energy of nodes when selecting cluster heads, limits number of nodes in each cluster and sends the data to the base station by means of improved inter-cluster transmission, so that the protocol can reduce the energy consumption of nodes and balances the energy consumption among clusters. Simulation results show that the protocol can reduced energy consumption of WSN and prolong the network lifetime.

Key words: Wireless Sensor Network(WSN), routing protocol, energy-efficient, inter-cluster transmission
