Target sensing and information monitoring using wireless sensor networks have become an important research field. Based on two-dimensional plane research, information monitoring, and transmission for three-dimensional curved target events, due to the uneven deployment of nodes and failures in sensor networks, there are a lot of coverage loopholes in the network. In this paper, a method of detecting and repairing loopholes in monitoring the coverage of three-dimensional surface targets with hybrid nodes is proposed. In the target monitoring area where the hybrid nodes are randomly deployed, the three-dimensional surface cube is meshed, and the coverage loopholes are gradually detected according to the method of computational geometry, and then, the redundant mobile nodes around the coverage loopholes are selected. According to the calculated distance to cover the moving direction and distance of the loophole, the virtual force is used to adjust the mobile nodes to repair the coverage loopholes. Simulation results show that compared with other algorithms, this algorithm has a higher utilization rate of mobile nodes, uses fewer nodes to complete coverage, reduces network coverage costs, meets the overall network coverage requirements, and has lower mobile energy consumption and longer network life. The actual scene further verifies the good connectivity and high coverage of the whole network.

无线传感器网络中混合节点的三维表面覆盖漏洞的修补方法

使用无线传感器网络的目标感测和信息监视已经成为重要的研究领域。基于二维平面研究，信息监控和三维弯曲目标事件的传输，由于节点的不均匀部署和传感器网络的故障，网络中存在很多覆盖漏洞​​。提出了一种在混合节点的三维表面目标覆盖监测中检测和修复漏洞的方法。在随机部署混合节点的目标监控区域，对三维表面立方体进行网格划分，并根据计算几何方法逐步检测覆盖漏洞，然后选择覆盖漏洞周围的冗余移动节点。根据计算出的覆盖移动方向的距离和漏洞的距离，使用虚拟力来调整移动节点以修复覆盖漏洞。仿真结果表明，与其他算法相比，该算法具有更高的移动节点利用率，使用更少的节点来完成覆盖，降低了网络覆盖成本，满足了整个网络的覆盖要求，具有更低的移动能耗和更长的网络寿命。实际场景进一步验证了整个网络的良好连通性和高覆盖范围。使用更少的节点来完成覆盖，降低网络覆盖成本，满足整体网络覆盖要求，并降低移动能耗并延长网络寿命。实际场景进一步验证了整个网络的良好连通性和高覆盖范围。使用更少的节点来完成覆盖，降低网络覆盖成本，满足整体网络覆盖要求，并降低移动能耗并延长网络寿命。实际场景进一步验证了整个网络的良好连通性和高覆盖范围。
