Framed-slotted ALOHA with estimation by pilot frame and identification by binary selection for RFID anti-collision

In RFID systems, a collision prevents a reader from identifying tags rapidly, and it is very important due to a limited function of passive tags. In this paper, we propose an efficient anti-collision protocol with estimation by pilot frame and identification by binary selection. Performance of the proposed algorithm is shown to be better than the other algorithms up to 7.3% ~ 21.9%.
