Comparative analysis of RFID anti-collision algorithms in IoT applications

Abstract

The automatic identification or tracking system from tagged objects normally deploys a Wireless communication technology named Radio Frequency Identification (RFID). During the identification process, the communication channel is shared between the reader and tags. Increasing the number of tags, the collision problem is getting worse. In this paper, the comparative analysis results of the selective three slotted-Aloha anti-collision protocols, Q, QT and FQT-algorithms are presented. The information will help to select the correct anti-collision techniques for an IoTs application which required a large number of tags
