针对传感器网络难以实现完全覆盖的情况,研究陷阱覆盖方式下陷阱空洞的检测和修复,提出了分布式的检测和修复方法.陷阱空洞检测方法可以让节点分布式自主地确定空洞边界曲线,从而得到精确的空洞信息,判断出该空洞是否是陷阱空洞.陷阱空洞修复方法基于边权图的概念,通过多轮计算确定新增节点的位置.所提出算法充分考虑了监测区域的边界效应,并且比现有算法在需要新增的节点数目和节能方面更有优势,仿真结果表明了它的有效性.
Aiming at the problem that the sensor network can not be completely covered, the detection and repair of trap holes under the trap coverage are studied, and the distributed detection and repair methods are proposed. The trap-hole detection method can allow nodes to determine the void boundary curves autonomously and distributedly, Accurate hole information to determine whether the hole is a trap hole.Trap hole repair method based on the concept of the sidebar graph, through a number of rounds to determine the location of the new node.The proposed algorithm takes full account of the monitoring area of the border effect, and the ratio The existing algorithms have more advantages in terms of the number of new nodes to be added and energy saving. The simulation results show its effectiveness.
