-Radio frequency identification (RFID) is an automatic identification system working through radio frequency (RF). Tag collision occurs while two or more than two tags deliver their unique identification (UID) to the reader. Since collision, which would significantly affect the efficacy of RFID, has been one of the major study issues for RFID technology, we have developed a solution, bit compet...

RFID uses radio frequency waves to track and identify objects. RFID system consists of tags and readers. Passive RFID tags are more popular now days due to its simpler circuitry, lower weight and lower cost. Generally passive tags are attached with an object for unique identification. A tag contains information about the particular product, to which it is attached. RFID reader is used to interr...

Recent technological advances have motivated large-scale deployment of RFID systems. However, a number of critical design issues relating to efficient detection of tags remain unresolved. In this paper, we address three important problems associated with tag detection in RFID systems: (i) accurately detecting RFID tags in the presence of reader interference (reader collision avoidance problem);...

In passive RFID systems, tags are arbitrated on the Medium Access Control layer by the Framed Slotted Aloha protocol. Tags select an arbitrary slot to send their information, such that the reader receives slots with no responses, single tag responses or multiple tag responses, generating empty, singleton and collision slots, respectively. In order to maximize the system throughput, precise know...

The performance of a passive RFID system in a dense multi-reader environment is limited by both reader-to-reader interference and reader-to-tag interference. In this paper, we formulate a practical RFID system model which takes into account the non-linear demodulation of the tags and the transmission spectrum of the readers. Using this model, we derive a novel linear programming formulation to ...

Advances in wireless and mobile communication technologies have enabled the development of various RFID-based systems and applications in addition to the extension of the tag reading range of mobile readers. Thus, it has become commonplace that multiple readers concurrently attempt to read tags within ranges of the readers. However, this concurrent access among multiple mobile readers brings ab...

Radio frequency identification (RFID) systems have emerged as an efficient and cost effective solution for tracking objects containing passive RFID tags. The choice of passive RFID tag is due to its low cost and simplicity of implementation. The problem is to identify objects containing passive RFID tags. If there are multiple objects in the range of a tag reader, they all send their ID to the ...

Abstract At present, some existing tag anti-collision algorithms are used mostly in scenarios of fixed number tags and they perform poorly moving scenarios. Therefore, this paper proposes a double reader movement RFID method based on suffix, through the cloud platform computing, supply chain data sharing is realized. Tag usually use single reader. The proposed employs to expand recognition rang...

This paper investigates the potential interactions between reader and tag anti-collision algorithms of passive RFID (radio frequency identification) systems. Conventionally, reader and tag anti-collision algorithms are designed by assuming that they are independent from each other. In practice, however, readers and tags usually operate in the same frequency band. Therefore, contention between t...

This paper describes a new tree based anti-collision algorithm for Radio Frequency Identification (RFID) systems. The proposed technique is based on fast parallel binary splitting (FPBS) technique. It follows a new identification path through the binary tree. The main advantage of the proposed protocol is the simple dialog between the reader and tags. It needs only one bit tag response followed...
