Dynamic System Model for Optimal Configuration of Mobile RFID Systems
In many practical RFID applications tags are attached to items that pass through the reader's field moving at a constant speed, following a fixed path. The time-constrained presence of the tags in the identification region introduce the possibility that tags exit the system without being identified (lost tags). Reliability is a practical requirement in most applications, which implies that the portion of lost tags should be kept below a very small threshold. Therefore, the authors take this fact as the starting point in the design process. They present a mathematical model for RFID systems implementing Frame Slotted Aloha as the collision resolution protocol.
