A new anti-collision method for RFID systems
2011 IEEE 12th International Symposium on Computational Intelligence and Informatics (CINTI), 2011Anti-collision technology in RFID system plays an essential role in the process of recognizing tags. Framed-Slotted structure makes it more convenient and effective for ALOHA anti-collision algorithm. But when the number of tags, especially the range of tag number, is unknown, it will be very hard for the system to initialize the suitable frame size ...

An Infrared Ranging System for Automotive Anti-collision
2012In this paper, we present a high-frequency current source transmitter circuit, which uses the high-power composite pipe as the regulator and the high-speed op-amp as the feedback link. As matching the appropriate electrical parameters of the current output at high frequencies, the anti-collision system can be maintained in constant state and can be ...

Anti-collision methods for chipless RFID systems
2015 Asia-Pacific Microwave Conference (APMC), 2015Radio Frequency Identification enables automatic identification of objects with least human involvement. Chipless RFID is the low-cost alternative of conventional chip based system. In many application multiple tags collide with each other making the reading and identification challenging for the reader.

Analysis of anti-collision algorithms in RFID system
2009 IEEE International Conference on Communications Technology and Applications, 2009Tag anti-collision protocol is one of the most important issues in RFID research, and many new methods have been proposed to solve the problem. In this paper, main anti-collision algorithms are illustrated and analyzed. Consequently, the comparison of these algorithms is summarized, and the perspective of tag anti-collision issues is inferred.

An Improved Anti-Collision Algorithm for RFID System
2008 4th International Conference on Wireless Communications, Networking and Mobile Computing, 2008RFID system is widely used in wireless communication systems. Tag collision, causing the RFID reader cannot identify the tag data, is a serious problem when several tags use the same communication channel simultaneously. Framed slotted ALOHA algorithm is normally used to solve the RFID collision problem. However, it requires an exponentially increasing
