Multi-tag RFID systems
Successful object identification is the primary objective of Radio Frequency Identification (RFID) technology. Yet, a recent major study by Wal-Mart has shown that object detection probability can be as low as 66%. We propose the tagging of objects with multiple tags to address the fundamental issue of object detectability. We show that this strategy dramatically improves the efficacy of RFID s...
متن کاملA Multi-scale Nonparametric/Parametric Hybrid Recognition Strategy with Multi-category Posterior Probability Estimation
The synthesis of an effective multi-category nonlinear classifier with the capability to output calibrated posterior probabilities to enable post-processing is of great significance in practical recognition situations in that the posterior probability reflects the assessment uncertainty. In this paper, a multi-scale nonparametric and parametric hybrid recognition strategy is developed for this ...
متن کاملImproved Efficient RFID Tag Estimation Scheme
DFSA (Dynamic Frame Slotted Aloha) based anti-collision algorithms resolve the collision among the RFID (Radio frequency-ID) tags by adjusting the frame size for the incoming frame according to the number of un-identified tags. The system efficiency directly depends upon the estimated number of tags that contribute towards the frame size adjustment. In this paper, we propose an improved scheme ...
متن کاملA Broad-Typed Multi-Sensing-Range Method for Indoor Position Estimation of Passive RFID Tags
The RFID (Radio Frequency IDentification) system is paid attention as a technology that can realize a ubiquitous environment. Each RFID tag has a unique ID code, and is attached on some object with the information of the objects. A user reads the unique ID code using RFID readers and obtains the information of the object. One of the important applications of RFID technology is the indoor positi...
متن کاملThe Practicality of Multi-Tag RFID Systems
Radio Frequency Identification (RFID) is an increasingly popular technology that uses radio signals for object identification. Successful object identification is the primary objective of RFID technology (after all, the last two letters of the acronym “RFID” stand for “identification”). Yet, a recent major study by Wal-Mart has shown that object detection probability can be as low as 66%. In th...
