Abstract: Firstly, the advantages of radio frequency identification device (RFID) technology used in indoor localization is analyzed in this paper. Then one method of obtaining reference tag fingerprint information by use of average filter is proposed, one improved algorithm which uses the log distance model of path loss for interpolation to compute the received signal strength values of virtual reference tags is proposed according to the classic LANDMARC algorithm and VIRE algorithm, so that the localization accuracy is further improved. The experimental results show that the localization algorithm can significantly improve the localization accuracy.
Key words: communication technology; radio frequency identification; received signal strength indicator; indoor localization; algorithm; reference tags
