Impact of Tag Responsiveness on Gen2 RFID Throughput

It is well known in the research community that the throughput of Dynamic Frame Slotted ALOHA (DFSA) in RFID system can be maximized when DFSA frame size is set to the number of tags. However, related works often neglect the fact that tag responsiveness is of a stochastic nature, depending on the tag hardware performance in the wireless channel. Therefore, as number of tag responses may not be equal to the number of tags located in the interrogation area, corrections to the standard simulation models should be applied. In this paper, we provide the corrections that are based on Tag Read Probability (TRP) metrics. At first, numerically, TRP was retrieved by usage of fully-configurable open-source Software Defined Radio (SDR) RFID reader in an indoor non-fading radio channel at the single frequency and constant output power, while considering reliable communication parameters in the environment of single and a pair of commercial Gen2 RFID tags. Then, TRP is statistically modelled, and the implications to the throughput are shown.
