With the development of intelligent networks, wireless sensor networks have been widely used. In reality, optimizing the network coverage is the basis for follow-up research. In this piece of work, we proposed three improved algorithms to different situations based on virtual force. First, we increase the force of uncovering grids to nodes and update uncovering grids by constructing the function. On the basis of this, taking the existence of different obstacles and the problem of node’s adaptive movement in the network into count, this paper gives the specific analysis methods. Finally, aiming at the existence of moving obstacles, this paper gives the specific solution to track and cover. The simulation results show that the algorithms not only improve the coverage performances but improve the convergence speed.
