摘　　要：为了完成数据的采集和传输的同时最小化能耗,无线传感器网络需要节能且健壮的通讯协议,国内外学者提出了一些基于能量的簇头选择算法。然而这些所提算法里面均未考虑簇头邻居的能量和数目。该文提出了一个基于能量的簇头选择算法EBC,该算法中簇头是基于节点和节点邻居的能量和节点的邻居数目来选择的。实验表明EBC相比LEACH提高了无线传感器网络的生命周期。Wireless sensor network requires robust and energy efficient communication protocols to minimize the energy consump?tion as much as possible.Numerous energy-based cluster head election algorithms have been proposed and implemented.Howev?er,the capacities and workloads of the neighbors of cluster heads have not been considered in large wireless sensor networks.A en?ergy-based cluster(EBC)head selection scheme where cluster heads are elected based on the energy value of a node and the ener?gy values of its neighbors and the number of its neighbors is proposed in this paper.Simulations in network simulator have proved that EBC cluster head selection scheme has improved the lifetime of the network compared to the LEACH protocol.
