Abstract
Localization is one of most important technolony of wireless sensor network, in order to reduce the error of node localization for DV-Hop algorithm in wireless sensor networks, a node localization algorithm based on Multi-population Particle Swarm Optimization(MPSO)algorithm and DV-Hop algorithm is proposed. The hops between nodes are modified by threshold value to improve the estimating accuracy of the hop distance, and then in the third stage of DV-Hop algorithm which MPSO algorithm is used to correct the localization error, the simulation analysis of MPSO-DV-Hop algorithm is carried out on MATLAB2008. The results show that the algorithm can improve the localization accuracy of the sensor without increasing cost situation. It has a high pratical value.关键词
