摘要
为了最大限度延长无线传感器网络的使用寿命,本文分析了LEACH协议并在此基础上提出了一种新算法。该算法主要在簇首选取上进行了改进。簇首选择由原来的随机选取到现在的固定放入。理论和仿真结果证明,该算法要优于LEACH协议,使整个网络的生命周期延长。
In order to m0ximize the life of the wireless sensor networks, this paper proposes a new algorithm based on the analysis of the LEACH protocol.The new algorithm is mainly improved on the selecting of cluster head. This paper uses a fixed way to choose the cluster head instead of random selection. The results of theoretical and simulation prove that the new algorithm is superior to LEACH protocol, and prolongs the whole wireless sensor networks＇ life cycle.
