چکیده
Indoor localization algorithm has low precision and high cost. Based on the VIRE algorithm, this paper proposes a RFID technology based on particle swarm optimization algorithm. Firstly, the improved threshold of wavelet algorithm to the read signal for de-noising and reduce the signal strength value fluctuations generated error; and then the weighted localization to improve the positioning accuracy of the virtual tags; at last, the particle swarm algorithm to identify the label virtual optimal solution. Simulation experiments show that the algorithm can effectively improve the location accuracy, time can be reduced.
