RFID identification—design and optimization
This chapter addresses the fundamental RFID tag identification problem, namely reading all IDs of a given set of tags, which is needed in almost all RFID systems. Because tags respond over a shared wireless medium, tag identification protocols are also called collision arbitration, tag singulation, or tag anticollision protocols. Tag identification protocols need to be scalable as the number of tags that need to be identified could be as large as tens of thousands with the increasing adoption of RFID tags. An RFID system with a large number of tags may require multiple readers with overlapping regions. In this chapter, we first focus on the single-reader version of the tag identification problem and then extend our solution to the multiple-reader problem.
