Novel Tag Anti-Collision Algorithm with Adaptive Grouping
For RFID tags, a Novel Tag Anti-collision Algorithm with Grouping (TAAG) is proposed. It divides tags into groups and adopts a deterministic method to identify tags within group. TAAG estimates the total number of tags in systems from group identifying result and then adjusts the grouping method accordingly. The performance of the proposed TAAG algorithm is compared with the conventional tag an...
متن کاملResearch of Matrix-based Grouping Method on Anti-collision Algorithm for RFID Tag Identification
Abstract Currently, the Binary Search Tree (BST) algorithm is mainly used for continuous identification signal processing on active RFID tags. However, tag population is unlimited increasing. With using the BST, the number of identified tags is limited at an average period of time. In this paper, we propose the BST algorithm of the matrix-based grouping to accelerate the recognition speed of ta...
متن کاملAdaptive splitting and pre-signaling for RFID tag anti-collision
— In an RFID system a reader requests tags to send their IDs by RF signal backscattering for the purpose of identification. When multiple tags respond to the request simultaneously, tag collisions occur and the tag identification performance is degraded. There are several tag anti-collision protocols proposed for reducing tag collisions. The protocols can be categorized into three classes: ALOH...
متن کاملAn Adaptive Memoryless Tag Anti-Collision Protocol for RFID Networks
* This work was funded by SK Telecom under Contract Number KU-R0405721 to Korea University. Abstract— Tag collision arbitration for passive RFID tags is significant for fast identification. This paper presents an adaptive memoryless tag anti-collision protocol which is an improvement on the query tree protocol. To identify tags efficiently, we use information about tags the reader already know....
