Abstract: For the covering problem in three-dimensional environment of wireless sensor network, the article puts forward a covering algorithm related with area division and virtual forces in three-dimensional. In accordance with the idea of virtual forces and area division, suction source is placed in the center of each sub-region. The deployment range of node can be readjusted by resultant including gravitation of suction source and the force between nodes. The simulation results confirm the algorithm. The algorithm can improve the coverage efficiency of the entire region and reduce the energy consumption.
