Because of the maturation of wireless technologies, the wireless sensor network has been used in various applications, especially in\r\nthe environmentalmonitoring. After the nodes are deployed on the surveillance field, nodes will die due to the limited energy of the\r\nnode or accidental events, inducing the coverage holes and the break of the transference path. To tackle this problem, researchers\r\nhad proposed the rebuild network topology, such as adding Relay nodes. However, it costs a lot to build such a system. Therefore,\r\nin this paper, we would like to propose anothermethod to tackle the dying nodes as well as the cost. Specifically, we propose a holes\r\nhealing scheme. In order to check its feasibility, we use the analysis of mathematics to acquire the value of the parameters for the\r\nholes healing scheme. With the parameters, we could use the simulated result to prove the effectiveness of the scheme. The result\r\nshows that with the appropriate parameters we could confirm and extend the lifetime ofWSN to infinity.
