Experiments for Leveled RFID Localization for Indoor Stationary Objects

Based on the multiple power leveled passive RFID system Chan and Zhang [21] proposed, there are three innovative indoor localization algorithms, namely the leveled nearest-neighbor, leveled multilateration and leveled Bayesian inference, to locate stationary objects. In order to examine these algorithms in a realistic circumstance, we carry out experiments in a laboratory environment. The hardware of the RFID system in use is the Alien Technology development kit. The experimental results are consistent with the outcomes from the computer simulations. We are able to confirm that the average localization error results for these algorithms are quite small.
