摘要

无线传感器网络（W SNs）中簇头与基站的通信方式可分为多跳和单跳2种。如果采用多跳方式

靠近基站的簇头因传送数据较多而导致较早死亡;而在单跳方式中

远离基站的簇头因传送数据能耗太高而很快死亡。针对上述问题

提出一种基于不均衡分簇的数据收集算法

使靠近基站的簇的规模小于远离基站的簇。实验表明:不均衡分簇的数据收集算法能有效地延长网络的生命周期。

Abstract

Communication modes of cluster heads and base station in sensor networks can be categorized into two types:multi-hop and single-hop.If the previous is adopted

cluster heads closer to the base station tend to die earlier because more data packets are needed to transmit.Alternatively

if all cluster heads transmit data packets directly to the base station

nodes further from the base station will die much more quickly than those closer to the base station.Aimed at the problems

an algorithm of data gathering based on unequal clustering is proposed.The algorithm enables that clusters closer to the base station have smaller size.Experament results show that the proposed algorithm is effective for prolonging the network lifetime.
