Fair Reader Collision Avoidance (FRCA) protocol is a centralized protocol based on the TDMA and FDMA methods, which FRCA1 presented to reduce the reader-to-reader collision and FRCA2 introduced to decrease reader-to-tag collision. Among them, the literature proposes a dynamic multi-ary query tree collision protocol for RFID systems which can completely eliminate empty slots and greatly reduce collision slots. The proposed scheme is based on an iterative process between reader and tags which aims at locating all collision bits and dynamically encoding them to optimize . In this work, we propose an improved RFID anti-collision protocol (IMRAP) that complies with EPC global C1Gen 2 to maximize the identification performance and ensure the reliability of the UHF RFID system.To minimize tag collisions, RFID readers must use an anti-collision protocol. Different types of anti-collision protocols have been proposed in the literature in order to solve this problem. This paper provides an update including some of the most relevant anti-collision protocols.

Many anticollision methods and protocols have been presented to eliminate collision problems in RFID systems, but these proposed methods have some limitations and defects that afect network eficiency and throughput. In this paper, the proposed method is a dis-tributed protocol based on listening to the channel. In this paper we present a review of the best performing anti-collision protocols for RFID collision avoidance which are Geometry Distribution Reader Anti-collision (GDRA), Distance based RFID reader Collision Avoidance protocol (DRCA), Beacon Analysis based Collision Prevention (BACP), Distributed Efficient & Fair Anti-collision for RFID (DEFAR).To solve several types of reader collisions, we propose an efficient multi-channel reader collision avoidance (EMRCA) protocol, which is suitable for the multiple readers RFID system.

In the mobile tags estimation model, we use superposition principle of Poisson process to solve the tag estimation problem. Based on these models, a new anti-collision algorithm specifically for the mobile RFID tags is proposed. In dense reader RFID system, a number of readers in the same interrogation area want to access the channel at the same time suffer from reader collision problem. In this paper, we propose a distributed reader anti-collision MAC protocol (RAMP) for dense . Collisions happen when readers are in the interference range and start reading tags simultaneously, so it is necessary to use the right solution to control channel access in these systems. So far, various solutions have been proposed to control readers’ access to the communication channel. Fair Reader Collision Avoidance (FRCA) protocol is a centralized protocol based on the TDMA and FDMA methods, which FRCA1 presented to reduce the reader-to-reader collision and FRCA2 introduced to decrease reader-to-tag collision.
