A Study on Multi-Reader Anti-collision In Gen2 Protocol Based RFID Systems
Soo Min Han, Seung-Ho Shin · ITC-CSCC :International Technical Conference on Circuits Systems, Computers and Communications · 2007
RFID System recognizes the tag by receiving the tag for command that the reader transmitted. At this time, the readers located nearby may use same frequency, or several readers transmit the command to one tag at the same time disrupting one another-which is called RFID reader collision. Specifically, the distribution and logistics area require the real time identification of large quantity of products, and the identification of multiple tags and the method of operating the multiple readers determine the performance of overall RFID system. In this paper, we design the Middleware Moudle that uses the session field and mask value of Gen2 Tag in order to minimize the collision of readers and enable the multi-readers.
