与节点位置无关的无线传感器网络覆盖控制算法

摘要

提出一个分布的、与节点位置无关的无线传感器网络覆盖控制算法(a Location Independent Coverage Control Algo-ritlun for Wireless SensorNetworks,LICA).LICA采用基于节点分层成簇的思想,节点与邻居交换信息,并通过节点距离与覆盖模型找出覆盖节点.在保证覆盖性能的前提下,关闭覆盖节点的通信设备.仿真实验结果表明,LICA算法不仅可以提供高质量的覆盖性能,而且具有良好的节能性能.特别适合低成本、资源缺乏、工作在恶劣环境中的分布式无线传感器网络.%A location independent coverage control algorithm (LICA) is proposed in this paper. LICA adopts the hierarchical clustering idea. The neighboring nodes exchange the information and find out redundancy node in order to turn off their communications e-quipment. The simulation and analysis study demonstrate that the LICA not only provides the high quality of area coverage and good scalability, but also provides better performance in the energy efficiency. It is particularly suitable for the low-cost wireless sensor networks, especially when it is used in adverse circumstances lacking in resources.
