Abstract

A novel location algorithm based on geolocation algorithm and LANDMARC algorithm is proposed to improve the location accuracy of Radio Frequency Identification (RFID) system in non-line-of-sight (NLOS) environment. We compare this algorithm with the existing LANDMARC algorithm via two metrics: the mean location error and cumulative location error distribution in line-of-sight (LOS) and NLOS environments, respectively. Numerical simulation results show that the proposed algorithm is very simple, and it gives higher location accuracy in NLOS environment with little performance degradation compared with in LOS environment.
