The main study of traditional probability coverage problem in wireless sensor networks (WSNs) is aiming at two-dimensional space, however, most practical applications of wireless sensor network is placed in a three-dimensional sensor networks. Therefore, probability model is introduced for three-dimensional WSNs. This paper presents a method that using Voronoi divide to control the Scheduling of the probability model nodes in the target area. Also, a coverage control algorithm based on probability model (PMCCA) is proposed. We verify the effectiveness and the practice of PMCCA algorithm by comparing PMCCA algorithm to another algorithm in simulation experiment.
