In this work, an optimal Q algorithm based on a collision recovery scheme is presented. Tags use BIBD-(16, 4, 1) codes instead of RN16s. Therefore, readers can make a valid recognition even in collision slots. A way of getting the optimal slot-count parameter is studied and an optimal Q algorithm is proposed. The theoretical and simulation results show that the proposed algorithm can improve reading efficiency by 100% more than the conventional Q algorithm. Moreover, the proposed scheme changes little to the existing standard. Thus, it is easy to implement and compatible with ISO 18000-6C.
