Abstract :
Location Identification Based on Dynamic Active Radio Frequency Identification (RFID) Calibration (LANDMARC) is a typical system for indoor location using active RFID technology, where k-nearest algorithm is applied including 4 RFID readers and 16 reference tags. In this paper, we propose an efficient algorithm so-called Prior Measurement Error-correcting (PME) based on stationary readers for indoor location. The simulation results suggest that the new algorithm yields an accuracy of 17.11% higher than LANDMARC method.
