摘　　要： 覆盖空洞的产生会严重影响目标监测区域的网络性能。本文提出一种基于混合传感器网络的改进菱形网格覆盖空洞修复算法。该算法通过改进的菱形贴片方式,指导移动节点到指定位置消除空洞区域。仿真结果表明,与TNR算法相比较,本文算法可以有效减少移动节点的使用数目,提高移动节点的利用率。 The coverage holes seriously affect the performance of the target monitoring network. This paper proposes an algorithm of coverage-hole patching on the improved rhomboid mesh in hybrid sensor networks. This algorithm guides the mobile nodes to the specified location to eliminate the holes region through the improved rhomboid shaped patch. The simulation results show that,compared with TNR algorithm,the proposed algorithm can effectively reduce the number of mobile nodes,and improve the utilization ratio of mobile nodes.
