The popularization of RFID systems has conducted to large deployments of RFID solutions in various areas under different criteria. However, such deployments, specially in dense environments, can be subject to RFID collisions which in turn affect the quality of readings. In this paper we propose two distributed and efficient solutions for dense mobile deployments of RFID systems. mDEFAR is an adaptation...
“Reader” and “Tag” type devices are utilized in the Radio-Frequency IDentification technology for identification and tracking of objects. A tag can be “read” by a reader when the tag is within the reader's sensing range. However, when tags are present in the intersection area of the sensing ranges of two or more readers, simultaneous activation of the readers may cause “reader collision”. In order...
RFID technology suffers from a recurring issue: the reader-to-reader collision. Numerous protocols have been proposed to attempt to reduce them, but, remaining reading errors still heavily impact the performances and fairness of dense RFID deployments. This paper introduces a new Distributed Efficient & Fair Anticollision for RFID (DEFAR) protocol. It reduces both monochannel and multichannel...
