在没有地理位置信息的情况下,针对存在大量冗余传感器节点的传感器网络的节点调度问题,设计了一种基于闭合包围的冗余节点调度算法(RNSCE算法).该算法首先定义了闭合包围的概念,并给出了其相关性质;然后,提出了基于闭合包围方法的冗余节点以及覆盖空洞边界节点的判定规则;最后,提出了冗余节点调度方法,包括节点的休眠调度和覆盖空洞的修复两个方面.仿真结果表明,本文算法可以很好地维持网络初始覆盖性能,并有效降低活跃节点的数量.
In the absence of geo-location information, aiming at the node scheduling problem of sensor networks with a large number of redundant sensor nodes, a closed-loop redundant node scheduling algorithm (RNSCE algorithm) is designed. The algorithm first defines closed-loop Concept and its related properties are given. Then, the redundant nodes based on the closed enclosing method and the decision rules of covering the hollow boundary nodes are proposed. Finally, a redundant node scheduling method is proposed, which includes the dormancy scheduling of nodes and the coverage of holes The two aspects are repaired.The simulation results show that the proposed algorithm can well maintain the initial coverage of the network and effectively reduce the number of active nodes.
