Abstract Coverage area and network lifetime are two hot and significant issues of Wireless Sensor Networks (WSNs). Most existing coverage algorithms consider single round network deployment optimization, led to the problem of coverage decreased significantly and blind spots in the late network lifetime. This paper modifies the network coverage model by introducing node redundancy, cover set redundancy and their calculation method, and characterize the global network by local characteristics. And on this basis, RGA-D algorithm is proposed, RGA-D algorithm considers the influence of the current cover set for subsequent coverage set, considering the whole network lifetime. Simulation results show that the proposed algorithm achieves more effective enhancement on network coverage and a balance between the active nodes and network coverage, solve the problem coverage blind spots in the late network lifetime, can calculate the network survival time accurately, provide a time reference for the deployment of sensor networks again. And its performance outperforms or is similar to the existing excellent approaches in both optimization speed and solution quality.
