RFID is a wireless communication technology that provides automatic identification or tracking and data collection from any tagged object. Due to the shared communication channel between the reader and the tags during the identification process in RFID systems, many tags may communicate with the reader at the same time, which causes collisions. The problem of tag collision has to be addressed t...

Radio frequency identification (RFID) systems have emerged as an efficient and cost effective solution for tracking objects containing passive RFID tags. The choice of passive RFID tag is due to its low cost and simplicity of implementation. The problem is to identify objects containing passive RFID tags. If there are multiple objects in the range of a tag reader, they all send their ID to the ...

This is a work-in-progressproject.The purpose of this research is to help increasing the readers’ level of engagement using a multimedia approach. Previous studies have shown that active reading engage readers to keep reading as an interactiveway of learning. However, reading is a very personal experience for each reader due to readers’ understanding and different points of views. This project ...

For a dense RFID reader deployment, such as in a warehouse, where hundreds of readers will be positioned in a building, the interference between all these readers must be studied carefully to avoid disruption of operations. Strict RFID regulations and standards have been imposed, trying to address the problem of reader collision and also the problem of RFID devices interfering with other device...

You have at your desk the issue no. 1/2010 of the journal AUTOMATIKA with which begins my direct responsibility for its future development in the capacity of the Editor-in-chief. I would like to thank the KOREMA presidency for entrusting me with this responsibility. Special thanks to my predecessor Prof. Borivoj Rajković for the enormous effort he invested in regular publishing of the journal a...

1 The reader collision problem occurs when the signal from one reader interferes with the signal from other readers. Solutions like RTS-CTS are not applicable because a reader may communicate with multiple tags simultaneously. In this paper, we describe Pulse, a distributed protocol to reduce reader collisions. The operation of the Pulse protocol is based on periodic beaconing on a separate con...

This paper investigates the potential interactions between reader and tag anti-collision algorithms of passive RFID (radio frequency identification) systems. Conventionally, reader and tag anti-collision algorithms are designed by assuming that they are independent from each other. In practice, however, readers and tags usually operate in the same frequency band. Therefore, contention between t...
