基于分层定位模型的RFID定位算法研究
Study on RFID Location Algorithm Based on Hierarchical Location Model
摘要
Abstract
Identification and location provides critical information for modern intelligent parking system. The indoor location-sensing sys-tem LANDMARC based on RFID is used commonly. In this paper,analyze the classical LANDMARC algorithm with low cost and high accuracy,and propose a new indoor location algorithm D-LANDMARC based on two layer location model to avoid the error caused by using only the Euclidian distance of RSSI to select nodes for location computing. This algorithm is mainly composed of two parts,prelimi-nary locating and precise locating. Preliminary location filters out the reference label,and then based on the formula of "distance-loss"which uses tags signal strength difference for precise positioning. Compared with LANDMARC algorithm,the simulation result show that the method enhances the precision of indoor localization and has more balanced distribution of location error.关键词
