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-rithm for Wireless Sensor Networks,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 Distributed Independent Coverage Control Algo-rithm for Wireless Sensor Networks (LICA) is proposed.LICA adopts the idea of hierarchical clustering based on nodes, and nodes exchange information with neighbors, And find out the coverage node through the node distance and coverage model.Close the communication equipment covering nodes under the premise of ensuring the coverage performance.The simulation results show that the LICA algorithm can not only provide high quality coverage performance but also have good energy saving performance. Particularly suitable for low-cost, lack of resources, work in harsh environments in distributed wireless sensor networks.
