一种能耗平衡和密度感知的无线传感器网络分簇算法

摘要

WSN在实际应用中其能量是有限的,因其所处环境等,后期对能源的补充不易.为了延长其生命周期,此对LEACH算法进行了一些改进,根据节点自身能量情况以及节点密度情况来改进对簇头的选取方式,并提出了一种EDS-LEACH算法.通过用MATLAB对LEACH算法,EDS-LEACH算法以及2种其他文献的分簇算法进行仿真比较,验证了EDS-LEACH算法在网络的存活时间上较之LEACH算法以及另外两种分簇算法有显著提高.%The energy of a wireless sensor network is limited. In order to prolong its life cycle, an energy consumption balanced and density aware clustering algorithm based on LEACH protocol is proposed for wireless sensor networks, which is called EDS-LEACH. EDS-LEACH takes full consideration on the residual energy of each node and the density of the network during the process of cluster header selecting. The performance of EDS-LEACH is compared with original LEACH and two other clustering algorithms. The results show that the survival time of the EDS-LEACH algorithm in network is distinctly much longer than the LEACH algorithm and two other clustering algorithms.
