The node localization of wireless sensor has always been heatedly studied. To better solve the inaccurate node localization of three-dimensional wireless sensor space, this paper introduces the Voronoi model based on the particle swarm optimization, summarizes the node localization in the three-dimensional space into the objective function’s optimal solution, proves the principle of Voronoi model weighting edge having sensitive point, obtains the optimal solution by the principle, and thus effectively solves the node localization issue. According to the simulation experiment, this paper’s algorithm is superior to the comparison algorithm, which has better robustness and has improved the location accuracy.
