一种基于能耗平衡的无线传感器网络多层分簇算法
首发时间:2008-06-12
摘要:无线传感器网络中延长网络生命周期的一个重要方法就是将整个网络分成簇。在解决能耗平衡问题的分簇算法中,很少有算法来考虑 “热点”问题,整个网络寿命受到很大的局限。本文针对“热点”问题,提出一个基于能量平衡的多层分簇算法(EBCA),让离基站近的簇头可以更多的参与簇间通信,避免离基站近的簇头过早的耗尽能量。仿真结果显示,本文的算法有效的解决了热点问题,整个网络的负载比传统的分簇算法更加平衡。

A hierarchical clustering algorithm based energy balance in Wireless Sensor Networks
Abstract:In wireless sensor networks, it is a key technique to orginize the nodes into clusters ,which aims to minimize the energy consumption and prolong the lifetime of network. There are many clustering algorithms to solve the problem of unbalanced load, but the hot spot problem can hardly be considered. The networks lifetime is limited. In this paper, we proposed a hierarchical energy balance clustering algorithm (EBCA) which is unequal clustering size to solve hot spot problem. The clusters nearby the base station can deal with more inter-cluster communication. It aims to avoid died earlier than other cluster heads. Simulation results show that our algorithm can solve the hot spot problem efficiently. The whole networks load is more balanceable than conventional algorithms.
Keywords: Wireless sensor networks, cluster, hot spot, energy consumption balance
