Improved Distance Estimation using a Constellation of RFID Tags

Résumé

In this paper, we present a new approach using a group or a constellation of RFID tags in place of a single tag for distance estimation in order to improve it. We study the performance of a single active UHF-RFID tag operating at 433 MHz band compared to the constellation of four similar tags as its replacement. Distance estimations are performed using One-Slope Model (OSM). The improvements in distance estimations with constellations are based on averaging algorithm which helps to tolerate the noisy power measurements observed for a single tag. We also compare the performance of the constellations with different sizes to find the optimal size of a constellation. Experimental validations demonstrate the performance improvements while using constellations for distance estimation. For the best constellation the average estimation error was below 0.35 m and remaining below 0.84 m for more than 90% of the times with maximum error of 1.23 m.
