基于组合加权分簇的三维无线传感器网络覆盖控制方法*

节点部署是无线传感器网络的一个基本问题。针对传感器节点的能量有限，如何在有限的能量下，实现对目标区域的覆盖最大化，本文提出了一种能量有效的三维传感器网络覆盖控制算法，根据节点的可用能量，与邻节点的平均距离以及连通度的组合加权值来确定簇首节点，并通过仿真实验验证了该方法的能量有效性，研究结果表明，基于组合加权分簇的覆盖控制方法在保证一定的覆盖率以及连通性的前提下，降低了节点能耗，均衡了网络能量，延长了传感器网络的生存时间。

Coverage method based on combined weighted clustering for 3D wireless sensor networks

Node deployment is a fundamental problem in wireless sensor networks. Aim to using limited energy to achieve maximum coverage ratio, a coverage algorithm based on the energy-aware for 3D wireless sensor networks was proposed in this paper. Compare the combination of weights of the available energy, the average distance with adjacent nodes and the connectivity to determine the head node of cluster. Simulation results show that the coverage based on combined weighted clustering reduces energy consumption, balances network energy and extends lifetime of sensor networks, guarantees the coverage ratio and connectivity premise.
