Energy Efficient Optimization of Clustering Algorithm in Wireless Sensor Network

该文针对无线传感器网络是一种能量受限的网络,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;然后给出节点在通信中使用的能量模型,按照分簇的不同层数,分别对其成簇的数目进行理论上的优化分析,最后通过实验的方法验证优化的分簇算法能够满足能量有效性,对均匀节点能耗分布,提高网络生存时间有着重要作用。

Based on the strict energy limitations in wireless sensor network, 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 energy model used in the communication process is given, the optimization of the number of clusters according to different level of clusters is analyzed theoretically. The simulation results show that the rational number of clusters can unify the energy distributions of sensors and improve the lifetime of network.
