A ubiquitous learning system enables people to learn at any time, at any place and in any form. In particular, it has the context awareness property to provide learners the right information in the right place and at the right time. In this paper, we introduce the design concept for a ubiquitous learning system, U-Guide (Ubiquitous Guide) System. U-Guide integrates two existing technologies, Ad...

RFID is an automatic identification (Auto-ID) technology. Tiny data-carrying devices known as RFID tags are attached to objects. Readers can interrogate those tags wirelessly so that the associated objects can be identified. For instance, those objects could be supermarket articles to be scanned at the checkout. Other Auto-ID technologies include barcode systems, optical character recognition, ...

Recently, the range of available radio frequency identification (RFID) tags has been widened to include smart RFID tags which can monitor their varying surroundings. One of the most important factors for better performance of smart RFID system is accurate measurement from various sensors. In the multi-sensing environment, some noisy signals are obtained because of the changing surroundings. We ...

Cultural relics represent national or even global resources of inestimable value. How to efficiently manage and preserve these cultural relics is a vitally important issue. To achieve this goal, this study proposed, designed, and implemented an RFID and Sensor Web-enabled smart cultural relics management system (SCRMS). In this system, active photovoltaic subtle energy-powered Radio Frequency I...

We leverage increasing passive RFID tag memory to propose distributed RFID tag storage infrastructures (D-RFID stores). A D-RFID store is a large set of tags with significantly sized re-writeable storage. Interrogators interact with D-RFID stores by reading from and writing to tags, providing a wide range of possible applications that are otherwise resource-inefficient. Examples include tagging...

We demonstrate a simple RFID sensor network comprised of an Intel WISP and a commodity UHF RFID reader. WISPs are devices that gather their operating energy from RFID reader transmissions, in the manner of standard RFID tags, and further include sensors, e.g., accelerometers, and provide a very small-scale computing platform. We believe that this makes them an attractive alternative to motes fo...

RFID technology has many potential applications that would ease object identification seamlessly. One of its potential benefits to government is the adoption of RFID tag as embedded smart material within vehicle license plate. However, adoption of RFID in vehicle license plate is fragile from various RFID attacks while efforts to improve its security will lead to additional cost. Enhancing RFID...
