| Abstract: | 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. |
