基于距离的无线传感器网络覆盖洞修复方法

针对静态无线传感器网络中经常出现的覆盖洞问题,在基于移动节点的三角形逐个贴补算法的基础上,将已经确定位置的移动节点加入算法进行改进,并根据几何原理指导下一个移动节点移动到最佳位置。仿真结果表明:改进后的算法以更少的移动节点修复覆盖洞,并提高了覆盖度和网络性能。

Repair method for coverage holes of wireless sensor networks based on distance

Aiming at problem of coverage holes in static wireless sensor networks,on the basis of patching algorithm of triangle by triangle based on mobile nodes,put the mobile nodes whose positions are determined into the algorithm for improvement,and guides the next mobile node to the best position using geometry principle.Simulation results show that the improved algorithm recovers coverage holes with less mobile nodes,and improves the coverage and network performance.
