摘要: 在无线传感器网络(wireless sensor network, WSN)中, 如何解决漏斗效应、有效平衡节点的能量分布, 是延长网络生存时间的关键问题. 针对漏斗效应提出一种基于低功耗自适应集簇分层型(low energy adaptive clustering hierarchy, LEACH)协议的改进簇首控制算法(cluster control based on LEACH, CC-LEACH), 通过sink 辅助选择簇首分布. 仿真证明, 这种新型簇首选择机制能更好地进行能量均衡, 延长网络生命周期.

Abstract: In wireless sensor network (WSN), to effectively balance energy of nodes and prolong survival time of the network is a key problem. To solve the problem, this paper proposes an algorithm named cluster control based on low energy adaptive clustering hierarchy (CC-LEACH) based on LEACH. Using this algorithm, cluster heads are selected by the sink. Simulation results show that the method has advantages in terms of energy balance and network lifespan.

Key words: funnel effect, energy balance, low energy adaptive clustering hierarchy (LEACH), wireless sensor network (WSN)
