Design of a RFID anti-collision protocol for RFID Tag-Reader Communications

Project Topic:
Due to the receding cost of manufacturing, Radio Frequency Identification (RFID) systems are used in a variety of applications to tag and track physical objects. A typical RFID system operation involves numerous tags to be present simultaneously in the interrogation zone of a single reader. Any responses from the tags can collide, leading to retransmission of tag information that results in increase in the access delay. Besides, readers physically located near one another may interfere each other. Such reader collision must be minimized. In this project, we will design a procedure to deal with tag and reader problems, while taking environmental effects into account.
