Abstract. A mathematical model of anti-collision process of RFID-tags in discrete time with a random delay of activation markers is proposed. The model allows to estimate the number of tags in range of reader at the time limit of identification. Based on the proposed simulation model of anti-collision Protocol, the range of the random delay values for activation of the labels may be recommend, and importance of the duration of single label reading may be estimated. Results of the model experiments demonstrate advantages of the proposed procedure.
Keywords: radio-frequency Identification, RFID-label, multi-access, collision, mathematical model of resolution of conflicts, anti-collision protocol, time of RFID-tags identification
