中文摘要：

为了使低功耗自适应集簇分层型协议（Low Energy Adaptive Clustering Hierarchy,LEACH）中簇头选举更加合理,网络生命周期更加长久,对低功耗自适应集簇分层型协议的内容进行了研究。分析了LEACH运行过程中传感器的能量消耗,并对LEACH簇头选举过程中阈值的计算进行了改进,增加了能量因素,提出了2种新型的阈值计算方法。最后,利用MATLAB仿真软件对LEACH算法和2种改进算法进行了仿真。仿真结果表明改进算法起到了理想的效果,延长了网络生命周期。

英文摘要：

To further rationalize the cluster head election of LEACH（ Low Energy Adaptive Clustering Hierarchy） and extend the network life cycle,we make a research into LEACH and an analyzation of the energy consumption during the running process of LEACH. We also put forward an improved algorithm in the process of cluster head election of LEACH by adding two energy factors leading to two new corresponding threshold calculation methods. At last,we simulate the LEACH algorithm and the two improved algorithms via MATLAB,which turns out that the improved algorithms reach the desired effect and effectively extend the network life cycle.
