An important challenge in radio frequency identification (RFID) systems is the collision concern. When an interrogator send a request, it has several tags to answer to in its transmission range, and a tag collision has occurred. The interrogator must be able to recognize tags as rapidly as possible. A collision problem is a powerconsuming occurrence that diminishes the operation of RFID structure. This article proposes a tag anti-collision power-clustering RFID algorithm for all tag identification. The tags are boundaries into the several power level clusters based on distances of the reader. Specifically, in the proposed algorithm, tags and readers use of balanced incomplete blocks design (BIBD) to reach a fast identification. In a BIBD matrix, any two columns intersect exactly in one component that makes it possible for easy transmission of any two tags via the tag's identification in their read cycles. The aim of this article is to propose a joint organization that while decreases power consumption increases the working lifetime of RFID structure. The reader can get each tag ID by distinguishing each unit of BIBD symbols, one by one. The use of proposed algorithm brings about a great improvement in the power consumption and identification time. K E Y W O R D S algorithm, collision, power consumption, RFID

“…The maximum range of the reader is set up to 5 m. According to the EPC Class1Generation2 standard, tags have a 96-bit RFID ID. 30 Virtual tag's RSSI value is achieved dynamically according to an interpolation algorithm. The simulation eight times for each number of tags from 50 to 400 using MATLAB is carried out.…”

“…we will suggest an Improved anti-collision algorithm for RFID tags identification to connect with RFID reader. Depending on anti-collision protocols such as Pure Aloha (Additive Link On-line Hawaii), Slotted Aloha, Framed Slotted Aloha (FSA), Dynamic Framed Slotted Aloha (DFSA), Binary Tree, and Class-1 Generation-2 protocol [6]. We will do a comparison between some of these algorithms to get an efficient anticollision algorithm of tags identification to connect with RFID Readers.…”

The most important research in the world in these days, research that looking at the internet of thing's (IoT) topics and their applications. Most of these applications depend on RFID system, which includes RFID readers and tags. The important issues in RFID system or network are how we can reduce anti-collision between readers to identify and read tags data. In these paper, we suggest an Improved anti-collision protocol, which can be used to connect RFID readers with RFID tags and reduce the number of RFID tag's collisions. The simulation shows that an Improved Class-1 Generation 2 algorithm is better than Slotted Aloha, Class-1 Generation-2 (Number of Tags Known), Class-1 Generation-2 (Number of Tags Unknown) algorithms.
