| Abstract: | Under the situation of wireless sensor network redundancy deployment, we iormulate the mathematical model of WSN＇s coverage optimization, in which the objective function is the weighted sum of coverage function and utilization function of nodes. Based on the estimation of distribution algorithm, the opti- mization strategy for coverage problem is proposed. Experiments show how the weight of objective function, sensing radius of sensors and different deployment model affect the optimization results. |
