Abstract

EPC Q scheme is a very popular protocol in RFID, in which the reader uses parameter Q to vary the slot number that tags can select. In this paper, we propose a new algorithm based on this scheme. We first propose a fast and efficient tag estimation method according to stochastic analyses on the first three slots of each frame, then propose a new ALOHA based multi-branch anti-collision scheme. Both theoretical analysis and simulation results indicate the proposed scheme can improve a lot than the standard EPC Q algorithm and the modification is slight.
