摘要：DV-Hop positioning algorithm based on distance vector routing and GPS location was put forward. The paper presents a localization algorithm for sensor networks based on mobile beacon localization in wireless sensor networks. Wireless sensor network localization accuracy depends on the density of beacon node. In this paper, using the Monte Carlo localization algorithm to solve the problem of node localization in wireless sensor network node mobility, and was improved. The paper presents a novel improved node localization algorithm of wireless sensor network. The simulation results show that the improved algorithm can improve the positioning precision, reduce the amount of computation algorithm, and improve the positioning efficiency. ? 2014, Journal of Chemical and Pharmaceutical Research.
