An RFID Best Effort Mechanism for in Motion Tracking Applications

In this article, the authors propose an algorithm that reduces useless responses for RFID systems in a motion environment, for tracking applications. The mechanism achieves its goals by reducing the number of packets exchanged between readers and tags. They analyze the behavior of their proposal by considering the average number of identification rounds. With extensive simulations using an RFID module for the ns-2 simulator, the authors show the benefit of the proposed mechanism. When compared to the Pure Q Algorithm and Binary Tree Slotted Aloha, their mechanism reduces the number of packets up to 43%, which is a good result in terms of performance of motion applications and energy consumption of the devices used in the communications.
