چکیده
Anti-collision algorithms are very important to solve the anti-collision problem in multi-tag and multi-reader environment. The anti-collision algorithm is divided into the anti-collision algorithm for multiple tags and the anti-collision algorithms for multiple readers. The anticollision algorithms for multiple tags are largely divided into tree-based deterministic algorithms and slot aloha-based probabilistic algorithms. In this paper, different multi-tag anticollision algorithms compatible with the EPC Gen2 protocol (ISO 18000-6C protocol) are analyzed and simulated under different conditions, and the latest UHF frequency allocation regulation of China is taken into consideration.

An Efficient Anti-Collision Method for Tag Identification in a RFID System
Radio frequency identification (RFID) technology is becoming increasingly attractive because of its high storage capacity and reprogrammability. There is a challenge to be overcome when a reader needs to read a number of tags within the reader’s interrogation zone at the same time. In this paper, we present an anti-collision scheme in a RFID system. The scheme is based on the dynamic framed ALO...

A highly collision-resistive RFID system multiplexes communications between thousands of transponders and a single reader using TH-CDMA based anti-collision scheme. This paper focuses on the back-end design consideration of such an RFID system with the deployment of high-level modeling techniques, accompanying a technical comparison of physical-level description, hardware-based emulation, and s...
متن کاملCommunication Scheme for a Highly Collision-Resistive RFID System
A highly collision-resistive RFID system multiplexes communications between thousands of tags and a single reader in combination with time-domain multiplexing code division multiple access (TDCDMA), CRC error detection, and re-transmission for error recovery. The collision probability due to a random selection of CDMA codes and TDMA channels bounds the number of IDs successfully transmitted to ...
متن کاملDCSK Multi-Access Scheme for UHF RFID System
DCSK modulation in chaos communication is a robust non-coherent modulation scheme. In this paper, the multiple-access DCSK scheme based on the OVSF code is proposed. Using the multiple-access DCSK scheme in RFID system, a DCSK-RFID system is presented. In the presented DCSK-RFID system, we use the DCSK for tag modulation for its low complexity and the simple receiver of the DCSK scheme is appli...
متن کاملAnti-Collision RFID System Based on Combination of TD and Gold Code Techniques
Radio-frequency identification (RFID) communication system known as auto-id has experienced tremendous growth worldwide, considering as a flexible mechanism for identification of objects. Degradation of data transmission due to external interference and interference of RFID system itself (tags and reader collision) is one of the most important factors to restrict the development of the RFID sys...
