A Multicast Anti-Collision Protocol for FTDMA based RFID system
نویسندگان
چکیده
RFID (radio frequency identification) is a key technology supporting emerging solutions for the automation of the identification service and the mass product management. A key issue is to reduce the average time taken to identifying tags, which is called average identification time. Focusing on the issue, the paper proposes an efficient multicast protocol which is applied to the anti-collision protocol of FTDMA (frequency time deivision multiple access) based RFID system. Thanks to the compactness of a multicast protocol, simulation result shows 29.5% improvement of average identification time.

متن کاملAn Efficient and Reliable Tree-based Anti-collision Protocol for RFID Systems with Capture Effect
In radio frequency identification (RFID) systems, if tags transmit their IDs simultaneously, a reader cannot correctly identify the IDs due to collision and the performance of RFID systems degrades by the collision. So, anti-collision protocols to reduce the number of collisions are required. The binary tree anti-collision protocol branches randomly in a tree to reduce collisions in the next id...

The Reader Collision Problem (RCP) is a bottle-neck decreasing the reading efficiency in multiplereader RFID systems. This paper proposed a novel anti-collision protocol – DRA (Distributed Reservation-based Anti-collision) protocol to solve the RCP in multiple-reader RFID systems. Temporal Cluster Headers (TCHs) are dynamically selected among the potentially interfered readers in DRA protocol. ...
