Book excerpt: This book examines the design of chipless RFID systems. The authors begin with the philosophy of RFID and its effect on commercial applications. Then, they discuss the chipless RFID systems and the application of chipless RFID systems, the advantages it provides compared to conventional barcode ID and chipped RFID tags. The text then covers chipless RFID components in block diagram representation and introduce FCC requirements which should be considered in the design procedure of each component. The third chapter is dedicated to the complex natural resonance-based design of chipless RFID tags. The next chapter concerns about the detection techniques introduced for the identification of chipless RFID tags. The fifth chapter is dedicated to the localization and anti-collision techniques in chipless RFID systems. Final chapter is chipless RFID tags as sensors. It provides some applications where the tag can be used as both ID and sensor. The tag specifications and detection issues are addressed in this section.

This book was released on 2012 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Radio Frequency Identication (RFID) is a technology that allows automatic identication of people or objects by incorporating the use of radio frequency waves to transmit data between networked electromagnetic readers and tags. RFID is considered an emerging technology for advancing a wide range of applications, such as supply chain management and distribution. However, despite the extensive development of the RFID technology in many areas, the RFID tags collision problems remain a serious issue. Collision problems occur due to the simultaneous presence of multiple numbers of tags within the reader zone. To solve collision problems, dierent anti-collision methods have been mentioned in literature. These methods are either insucient or too complex, with a high overhead cost of implementation. In this work, in order to improve the quality of RFID data collection, we propose novel deterministic and probabilistic anti-collision approaches. The main contributions of this study are summarised as follows: 1. We propose two novel deterministic anti-collision algorithms using combinations of Q-ary trees (Pupunwiwat and Stantic, 2009a, b, 2010c), with the intended goal to minimise memory usage queried by the RFID reader. By reducing the size of queries, the RFID reader can preserve memories, and the identication time can be improved. 2. We propose a novel frame-size estimation technique (Pupunwiwat and Stantic, 2010a, b) to minimise the number of slots and frames queried by the RFID reader and to maximise the system eciency. In addition, we introduce the probabilistic group-based anti-collision method (Pupunwiwat and Stantic, 2010d) to improve the overall performance of the tag recognition process. 3. We evaluate our proposed anti-collision techniques and perform a comparative anal- ysis, in order to nd the benets and disadvantages of each method. Additionally, in order to identify the best selection of anti-collision method, we propose two strate- gies for selective anti-collision technique management, i.e. a Novel Decision Tree Strategy and a Six Thinking Hats Strategy (Pupunwiwat et al., 2011). By correctly identifying the most suitable anti-collision method for specic scenarios, the quality of data collection can be improved.

Download or read book Simulation of an Anti collision Algorithm for RFID Systems Using a Code Division Multiple Access with Adaptive Interference Cancellation CDMA AIC Approach with Dynamic Processing Gain Gp written by Natalia Margarita Benitez Gutierrez and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radio Frequency Identification (RFID) Systems are modern wireless communication systems that transmit information from a transponder (tag) to a reader. RFID systems are well known because of their contactless feature. However, tag performance is limited by collision problems when multiple tags transmit simultaneously. Due to the collision problem, much research has been developed using anti-collision algorithms to enhance the systems' efficiency, save energy, and ensure the correct transmission of information. Most research has used a Time Division Multiple Access (TDMA) approach with anti-collision ALOHA-type algorithms. The time slots and frames of the tags are manipulated to deal with the collision problem. They work with different ALOHA protocol variants that are always trying to reduce the number of collisions compared to the previous techniques. The most promising of the ALOHA protocol variants is Dynamic Frame Slotted ALOHA (DFSA). In addition, research has been conducted with a Code Division Multiple Access (CDMA) approach, called CDMA with Adaptive Interference Cancellation (CDMA/AIC). The time slots are not used for this anti-collision algorithm; instead, Spread Spectrum (SS) technology and Processing Gain (Gp) were employed. In previous work, the Gp was a fixed value equal to sixty-four (64). In contrast, this research involved a CDMA/AIC approach with a dynamic Gp reached by generating different chip rates. This technique depended on the number of collisions from the previous run to resize the Gp for a subsequent run. CDMA gave the flexibility to use Spread Spectrum. The modulated signal was spread across the channel using orthogonal pseudorandom (PN) codes (generated for each tag) and was demodulated at the reader using the same PN code. The more spread the signal was in the channel, the greater the Gp. The research proved an enhancement in the system's performance compared to the previous work. The system's efficiency enhancement and the anti-collision algorithm were proven using MatLab as the simulation software. No hardware implementation was developed in this research. Both the CDMA and the modified DFSA code were exposed to the same conditions of noise (12, 9, 6 dB SNR), number of tags (20, 60, 80, 100, 150, and 200), number of simulations (1000), and Gp/slots (32, 64, 128, and 256). After the data was collected and processed, the performance of CDMA in noisy scenarios and with a large number of tags was faster and more efficient than DFSA. CDMA presented stability and fast information processing due to its error correction and code spreading features.

This book was released on 2016 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The current project presents the architecture of an efficient anti-collision technique for the identification of Class 0 RFID UHF tags. The architecture consists of two RCEAT (Reliable Cost Effective Anti-collision Technique) subsystems: PreRCEAT and PostRCEAT. The PreRCEAT subsystem is used to detect if the incoming messages have any errors in them. PreRCEAT applies a cyclic redundancy check to find an error in the ID (Identification) tag. The ID of the error-free packet will be sent to PostRCEAT, which uses a fast search lookup table to identify the incoming tag. It sends the output serially from the smallest ID to the largest ID. The system is designed using Verilog and simulated using Xilinx ISE. Simulation results show that the proposed architecture requires smaller cell area, and has lower power consumption compared to the popular Tree algorithm. The proposed system uses fewer logic gates, which minimize the implementation and operating cost.
