基于无源UHF RFID的一种室内定位算法
An Indoor Location Algorithm Based on Passive UHF RFID
摘要
Abstract
The k-nearest neighbor algorithm is commonly used in indoor location. It is simple but has large location error in the edge re-gion which degrades the entire algorithm’ s performance. In this paper,an indoor location hybrid algorithm applying for passive UHF RFID location system is mentioned by introducing the triangulation algorithm,in order to improve the issue. Simulation result proves that when the tag located on the edge of the area,the k-nearest neighbor algorithm and triangulation algorithm have high positioning errors, respectively about 1 m and 0. 6 m,while the hybrid algorithm’s location error is less than 0. 3 m. It means that the hybrid algorithm’s lo-cation error in the edge region is significantly smaller than the two mentioned algorithm,improving the positioning accuracy.关键词
