Abstract: In order to improve the coverage of wireless sensor networks (WSNs)， a dynamic deployment strategy was presented based on virtual force (VF) clustering. Based on VF， the traditional algorithm was divided into two phases by the presented strategy. First phase was to deploy clusters and second phase was to deploy the nodes in same cluster， which could reduce the interference between clusters and improve the coverage of network. The strategy was simulated in binary perceptual model， which showed that the strategy had a faster convergence speed and significant effect of optimization comparing with traditional VPF and VFA algorithm in the environment of a large number of nodes. The coverage of network eventually could reach more than 90% which could meet the requirement of coverage control of WSNs.
