ABSTRACT
Radio Frequency IDentification (RFID) technology promises to revolutionize the way we track items and assets, but in RFID systems, missreading is a common phenomenon and it poses an enormous challenge to RFID data management, so accurate data cleaning becomes an essential task for the successful deployment of systems. In this paper, we present the design and development of a RFID data cleaning system, the first declarative, behavior-based unreliable RFID data smoothing system. We take advantage of kinematic characteristics of tags to assist in RFID data cleaning. In order to establish the conversion relationship between RFID data and kinematic parameters of the tags, we propose a movement behavior detection model. Moreover, a Reverse Order Filling Mechanism is proposed to ensure a more complete access to get the movement behavior characteristics of tag. Finally, we validate our solution with a common RFID application and demonstrate the advantages of our approach through extensive simulations.

f2-sensors-12-10196: Relationship between read rate and distance.

Mentions: By further abstraction of the conclusions above we get the relationship between read rate p and distance s in Figure 2. Obviously, the distance s between tag and reader and the read rate p follow the relation as:(1)p={0ks+b<0ks+b0≤ks+b≤11ks+b>1where, b = −kS, and k is the slope of the line, so above equation can be further written as:(2)p={0s>Sk(s−S)0≤k(s−S)≤11k(s−S)>1
