Systematic error detection for RFID reliability

In this paper, we propose an approach to increase the reliability of RFID (radio frequency identification), not relying on the performance of each devices, but relying on a mechanism of entire networked system, which manages objects and/or people in the real world with RFID tags. We identified there exist many factors to reduce the accurate identifications of RFID tags, which results in the reduction of the total-system reliability. Moreover, we show the effect of our approach in diverse parameters such as the number of misidentifications, the length of transportations, the number of RFID readers.
