摘要 传感器网络中簇头与基站的通信方式可分为两种:多跳和单跳.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,提出一种基于非均衡分簇的数据收集算法,使靠近基站的簇的大小小于远离基站的簇.仿真实验表明,非均衡分簇的数据收集算法能有效地延长网络的生命周期. Approaches to transmit the collected data from cluster heads to the base station could 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,cluster heads further from the base station will die much more quickly than those closer to the base station.To address the problem,we propose an algorithm of data gathering based on unequal clustering.The algorithm enables that clusters closer to the base station have smaller size.Analytical results demonstrate that our proposed algorithm is effective for prolonging the network lifetime.
