摘　　要：无线传感器网络(WSNs)路由协议的设计受到传感器的节点特征、网络行为和应用需求等的影响,网络拓扑结构的变化对节点之间通信路径的影响非常关键。分簇是减少能量消耗和增强网络可扩展性的一种有效的拓扑控制技术。为了节约能耗,提出了能量平衡的非随机分簇算法。该算法采用最小能量分簇技术形成簇群,利用最小的通信距离来选择最优的簇头(CH)。仿真结果表明该算法延长了网络寿命,与集中式的LEACH-C算法相比,提高了能量利用效率。The design of routing protocols for Wireless Sensor Networks （WSNs） is challenged due to several constraints such as the individual characteristics of sensors, behavior of network, nature of sensing field and application requirements. Network topology change is a critical characteristic that has influence on communication path and load distribution among nodes. Clustering is an effective topology control technique to reduce energy consumption and provide network scalability. In this paper an energy-balanced deterministic clustering algorithm is proposed in order to improve energy and performance efficiency. The algorithm adopts minimum energy clustering technique to form clusters, and minimum communication distance to select optimal cluster head （CH）. The simulation results illustrate that the proposed algorithm prolongs the network life time and improves performance efficiency in comparison to Centralized Low Energy Adaptive Clustering Hierarchy LEACH-C.
