基于HDV-Hop的无线传感器网络大型室内定位算法研究
RESEARCH ON HDV-HOP BASED LARGE INDOOR LOCATION ALGORITHM FOR WIRELESS SENSOR NETWORKS
摘要
Abstract
Large indoor public places are common places in which wireless sensor network positioning technology is used.In view of the weak applicability of classic DV-Hop localization algorithm for wireless sensor networks and poor positioning accuracy, Hybrid DV-Hop(HDV-Hop)localization algorithm improves the deployment form of anchor nodes,data routing and coordinate calculation,Greatly improve the positioning accuracy,and expand the application of wireless sensor network positioning algorithm.In this paper,we further optimized the HDV-Hop algorithm to get a new localization algorithm that was more suitable for large public places.The new localization algorithm deployed the anchor nodes in the periphery of the more common rectangular shape in a large public place.At the same time, the average jump distance was selected as the average distance per hop for distance calculation.The simulation results showed that the new localization algorithm had higher positioning accuracy than the HDV-Hop localization algorithm and the RHDV-Hop(Rectangular HDV-Hop)algorithm using rectangular anchor deployment.关键词
