摘要
在低功耗自适应分层路由算法(LEACH)研究的基础上,针对它簇首负担过重的问题,提出了一种基于双簇首机制的改进算法。该改进算法通过在簇内选择次簇首传输数据,在一定程度上平衡了网络内能量损耗。在NS2上的仿真实验表明,与LEACH相比,它能延长网络生存周期。
In this paper, an improved algorithm was proposed based on LEACH, which selects another cluster head to tansmit data to the base station (BS), so it will balance the energy consumption in the network. The simulation experiments in NS2 show that it can extend the network lifetime compared with LEACH.
