Abstract
The third stage in classical DV-Hop location algorithm has big localization error, so this paper puts forward a localiza-tion method for wireless sensor network based on modified particle swarm optimization algorithm. Firstly, the defects of DV-Hop algorithm is analyzed, and the unknown nodes positioning problem is converted into the optimization problem, and then the modi-fied particle swarm optimization algorithm is used to optimize the problem, and the shrinkage factor is introduced to accelerate the search speed and precision, and find out the global optimal position of unknown nodes, finally the simulation experiment is car-ried out on Matlab 2012 platform. The simulation results show that the proposed algorithm improves the positioning accuracy of sensor nodes, and greatly reduces the positioning error.关键词
