Coverage is an important indicator of the quality of underwater sensor network (UWSN) service. It reflects the monitoring capability of the network nodes to the UWSN deployment area and determines the overall lifetime of the UWSN. In order to improve network coverage and prolong network lifetime, this paper proposed a combination algorithm of virtual three and particle swarm optimization (vf-pso). By the action of the virtual force, the underwater mobile nodes are moved to a relatively ideal position to maximize the network coverage. The virtual three is used to guide the optimization of the particle swarm so as to speed up the convergence of the particles to the global optimal solution. This algorithm not only effectively solves the problem of insufficient optimization ability of the virtual force algorithm, but also makes the particle swarm algorithm evolve towards the target solution that maximizes the area coverage. Simulation results show that the vf-pso algorithm can effectively improve the effective coverage of underwater monitoring area, and avoid void-hole problem, while ensuring network connectivity compared with the algorithm proposed earlier.
