“…The Schoute estimator [14] calculates the length of previous frame by multiplying the number of colliding slots in the frame with a factor of 2.39. This factor is the approximate value of the number of tags that will be transmitted in each collision slot in the finished frame.…”

“…According to standardized tags, the IDs with the EPC standard provide an improvement in the RFID system, facilitating integration with global networks. To meet the requirements to deploy multiple labels in industry, RFID increasingly requires labels with larger IDs [14]. Once an ID is written to the label’s microchip, it can be read or even changed (if needed).…”

The Industrial Internet of Things (IIoT) is often presented as a concept that is significantly changing industry, yet continuous improvements in the identification and automation of objects are still required. Such improvements are related to communication speed, security, and reliability, critical attributes for industrial environments. In this context, the radio-frequency identification (RFID) systems present some issues related to frame collision when there are several tags transmitting data. The dynamic framed-slotted ALOHA (DFSA) is a widely used algorithm to solve collision problems in RFID systems. DFSA dynamically adjusts the frame length based on estimations of the number of labels that have competed for slots in the previous frame. Thus, the accuracy of the estimator is directly related to the label identification performance. In the literature, there are several estimators proposed to improve labels identification accuracy. However, they are not efficient when considering a large tag population, requiring a considerable amount of computational resources to perform the identification. In this context, this work proposes an estimator, which can efficiently identify a large number of labels without requiring additional computational resources. Through a set of simulations, the results demonstrate that the proposed estimator has a nearly ideal channel usage efficiency of 36.1%, which is the maximum efficiency of the DFSA protocol.
