Energy and Distance Efficient Clustering Algorithm for Heterogeneous Wireless Sensor Networks

降低能耗、延长网络生存时间,是无线传感器网络设计的重要目标。提出了一种基于虚拟区域划分的适用于异构无线传感器网络的能量和距离有效分簇算法。仿真结果证明,此算法可有效地均衡簇内负载,延长网络的稳定周期和生存时间,提高网络的通信效率。

Reducing power consumption and prolonging the network lifetime were important targets of wireless sensor net works. So an energy and distance efficient clustering algorithm based on virtual area partition was proposed in this paper for het erogeneous wireless sensor networks. The simulation results illustrated that this algorithm had better load-balance between clus ters, prolongs the stability period and lifetime of networks and increased the efficiency of the communication in the whole net work system.
