| Abstract | This paper proposes an estimation method of number of tags which may be necessary in improving anti-collision performance for ALOHA-based RFID systems. In ALOHA-based anti-collision algorithms, since the performance of the multi tag identification can be improved by allocating the optimal slot size corresponding to the number of tags, it is needed to exactly estimate the number of tags. The proposed method uses the a priori knowledge of the relation between the expectation of the number of empty slots and the number of tags. After measuring the number of empty slots in one ROUND, we estimate the number of tags which corresponds to the expectation of the number of empty slots nearest to the measured one. Simulation results show that the proposed method is superior to conventional methods in terms of the estimation accuracy and the computational complexity. |
