摘要
针对异构传感器节点随机部署于被监测区域时容易产生覆盖漏洞的问题,提出一种基于取样直线扫描的覆盖漏洞修复算法,基于取样直线扫描,找到覆盖漏洞;通过移动传感器节点修复覆盖漏洞。该算法以完全覆盖被监测区域为优化目标,对于具有相同感知半径的同构传感器节点和具有不同感知半径的异构传感器节点同样适用。仿真实验表明:该算法能有效修复覆盖漏洞。
Aiming at problem that heterogeneous sensor nodes are randomly deployed in monitored area prone to genenate coverage leak,a coverage leak repair algorithm based on sampling straight line scan is proposed. Coverage leak are found based on sampling straight line scan; coverage leak are repaired by mobile sensor nodes. The algorithm treats the completely covered area by sensor nodes as the optimization goal and it is applicable for both homogeneous sensor nodes with the sensing radius of and the perception of the heterogeneous sensor nodes with different sensing radius. Simulation results show that the algorithm can effectively repair coverage leak.
