扩散方程用于RFID标签的室内定位
Diffusion function in RFID indoor location system
摘要
Abstract
The accuracy of location decreases seriously due to increasing of ranging errors when the Monte Carlo location algorithm is used to keep track of tag in Radio Frequency Identification (RFID) indoor location system. In this paper, the diffusion function is introduced into the Monte Carlo location algorithm, in order to research the relation between the accuracy of location and ranging error. Simulation results show that the accuracy of location is influenced not only by the value of ranging error, but also by the direction of tag's movement. For the same ranging error, the location is most accurate, when the direction of tag' s movement is perpendicular or parallel to the line from tag to reader.关键词
