Context-Aware Perspective Analysis Working Of RFID Anti-Collision Protocols

Abstract

RFID (Radio Frequency Identification) is the fastest growing technology, as many IoT devices are communicating via RFID technology. During the interaction among RFID reader and tag, collision happens in different ways like tag-to-tag, reader-to-reader and reader-to-tag collisions. Several anti-collision techniques are presented to resolve the collision issue. The RFID reader is like a physical sensor; thus, this study shows how the context-aware process is used in the reader and tag interaction. Furthermore, the authors have discussed the context of RFID anti-collision protocol by analyzing how a reader reads a tag and detects collision from a context-aware perspective. This study examines the method of working of anti-collision techniques from a context-aware perspective. The study gives a brief overview of how an anti-collision technique is working in RFID reader and tag communication. The core focus of this study is to compare anti-collision techniques and examine from a context-aware perspective. In this paper, RFID reader and tag communication is mapped with a context-aware cycle. By examining anti-collision techniques as an outcome, efforts have been made in this paper to determine which anti-collision technique is working better from a context-aware perspective. As per our findings, the discontinuous collision bit mapping algorithm (DCCMA) is a better approach as compared to other anti-collision techniques. Through this paper, we have found out that (DCCMA) anti-collision technique is better from a context-aware perspective.
