摘要
无线传感器网络规则部署的k-重覆盖模型特性直接影响着网络监测结果的全面性和准确性,决定上层协议的可靠性。本文通过计算几何理论,对正n边形网格k-重覆盖模型的物理特性进行理论分析得出,各模型在确保预设k-重覆盖需求下的节点临界部署距离阈值,为实现网络可靠覆盖控制算法设计提供基础;并通过MAT-LAB仿真实验研究获得了不同k-重覆盖需求下最优覆盖模型,为高效节点部署提供指导依据。
The completeness and accuracy of the monitoring result in network and the reliability of upper-layer protocols were impacted directly by the characteristics of k-coverage model for regular deployment in wireless sensor networks. In this paper, the physical characteristics of k-coverage model for n-polygon mesh was analyzed by calculating geometric theory obtained the results about the critical deployment distance threshold of nodes in these models under the preset k-coverage demand, it provides a basis for the design of reliable coverage control algorithm in network; and MATLAB simulation experiment studies conclude the best coverage model for different k-coverage demands, it helps to provide guidance gist of the efficient node deployment.
