Probability-Based K-Coverage Control Approach for Three-Dimensional Wireless Sensor Networks

JIANG Peng,CHEN Feng(Institute of Information and Control,Hangzhou Dianzi University,Hangzhou 310018,China)  
For the contradiction between the inherent uncertainty and strong fault-tolerance ability and robustness required in the system during the three-dimensional monitoring with wireless sensor networks,a probability-based K-coverage control approach for three-dimensional wireless sensor network,PKCCA,is proposed in this paper.The three-dimensional monitoring region is divided into a grid,and a greedy heuristic is used to determine the best placement of one sensor at a time until a preset upper limit on the number of sensors is reached,or K-coverage with probability T of the grid points is achieved.Comparing with the traditional random and uniform deployment,the simulation results indicate PKCCA uses less sensors to achieve the same coverage degree and detection precision or same sensors to reach higher coverage degree.The case of preferential coverage(preferential coverage degree and preferential monitoring precision) for sub-regions is also analyzed and simulated.
