摘要
针对无线传感器网络中传感器有限能量的特点,在分析LEACH算法的基础上,提出一种休眠簇头的算法——S_LEACH,以达到延长网络生存期的目的。新算法一次性选定所需要的工作簇头和休眠簇头,并且只分一次簇,节省了在LEACH中因再次簇头选举和分簇消耗的能量。使用Matlab进行算法改进前后的仿真,结果表明改进后的算法网络生存期延长了大约34%。
Aiming at the problem of limited energy of the wireless sensor network （WSN）,and based on the analysis of the LEACH algorithm,this paper proposed a new algorithm of sleeping cluster-heads （S_LEACH） to achieve the goal of prolonging the network lifetime by saving energy. The cluster-heads elected and clusters divided only at first time. In this way, the new algorithm avoids the energy consumption per round in LEACH algorithm. Comparing the new algorithm with the original one, simulation by MATLAB shows that the new one extends the network lifetime about 34%.
