| 摘 要： | 分簇被认为是延长无线传感器网络寿命的最有效的方法之一。本文首先说明根据节点数目以及分布区域特征,确定合理的成簇数目是分簇算法设计的核心;算法EBCO（Energy Balance Cluster Optimize）按照无线传感器网络运行过程中相邻簇簇头能量消耗速度信息来调整簇的大小,并且从能耗大的簇＂驱逐＂一些节点到能耗低的簇,从而平衡簇头之间的能量消耗。仿真结果表明,采用该能量平衡的传输策略时,能有效地平衡簇头间的能量消耗,较好地解决＂热区＂问题,延长网络生存时间。 |
| 关 键 词： | 无线传感器网络 能量平衡 网络寿命 驱逐 簇 |

| Abstract: | Clustering is one of the most efficient schemes for prolonging wireless sensor networks lifetime.How to decide the number of clusters,which is influenced with the total number of sensors and the characteristics of the disposed area,is the key idea in clustering algorithm.The algorithm EBCO（Energy Balance Cluster Optimize）based the difference of energy consume information between the neighbor cluster,let the cluster whose energy consume is higher drive some nodes out,and these nodes joined the other cluster whose energy consume is lower.The simulation of performance indicates that the proposed algorithm can balance the cluster heads＇ energy consumption,and prolong the network＇s life time. |
| Keywords: | wireless sensor network energy balance network lifetime drive out cluster |
