摘要：

在随机部署的无线传感器网络中，现有的节点调度算法不能同时保证工作节点均匀分布，使网络能耗不均衡。针对该问题，提出一种分布式、能耗均衡、与节点位置无关的无线传感器网络覆盖协议(EBLCP)。EBLCP在虚拟坐标的基础上建立临时集，节点只需与邻居中少量节点通信，比较这些节点的剩余能量从而竞选工作节点。实验结果表明，与NSVC协议和DELIC协议相比，EBLCP能保证较高的覆盖率，并延长网络生存时间。

Abstract:

In the Wireless Sensor Network(WSN) where nodes are randomly deployed, the proposed sensor scheduling schemes can not guarantee uniformly distributed and energy balanced at the same time. Aiming at this problem, a distributed Energy-Balanced Location-independent Coverage Protocol(EBLCP) is proposed. Based on virtual coordinate, EBLCP creates temp-sets in which working nodes are elected by residual energy of some neighboring nodes and its own. To compare with NSVC and DELIC, the simulation and analysis study demonstrate that the EBLCP not only provides high rate of area coverage, but also prolongs network lifetime to a large extent.

Key words: Wireless Sensor Network(WSN), coverage control, energy-balanced
