Recently, the radio frequency identification (RFID) technology has gained significant attention. One of the important performance issues in RFID systems is to resolve the collision among responses from RFID tags from the viewpoint of wireless media access control. We consider two kinds of smart antenna systems to enhance the RFID tag reading rate, namely the adaptive array antenna and the multi...

In this paper, we present and analyze the most fundamental constraint of RFID systems, power rectification. This issue plays an important role in development of long-range RFID systems. Rectifiers are the key components in power rectifications and efficiency of an RFID system. Therefore this paper is concentrated in investigating this major issue. To tackle this problem a novel Schottky Barrier...

Radio Frequency Identification (RFID) technology enables a new era of business optimization. RFID provides capturing large volumes of data at high velocity and can be used for identifying, locating, tracking and monitoring physical objects without line of sight. However, despite these benefits, this technology poses many new challenges in the current data processing and management systems. RFID...

RFID (Radio Frequency Identification) is one of the most growing technologies among the pervasive systems. Non line of sight capability makes RFID systems much faster than its other contending systems such as barcodes and magnetic taps etc. But there are some allied security apprehensions with RFID systems. RFID security has been acquired a lot of attention in last few years as evinced by the l...

Radio frequency identification (RFID) technology can automatically and inexpensively track items as they are moved through the supply chain. This can automate the whole updating and management system, thereby making the system work with a much smaller workforce and reducing the error that can occur because of interference by human beings. One of the major adv...

Introduction Contactless RFID technology holds promise for object tracking, supply chain, smart payment and security management. Most RFID systems have their own unique hardware and software interfaces and are therefore are not readily available in the plug and play mode. At UCLAWINMEC, we have developed a unique RFID middleware platform and this platform is being implemented in software to mak...

introduction: applying information technology in healthcare system is one of the most important criteria of the world health organization for evaluating the quality of healthcare systems of different countries. moreover, applying this technology in different parts of health care system can create great potentials for improving the quality of healthcare services. in this regard, radio frequency ...
