Introduction In the past years a significant change for computer networks occurred: the rise of direct device-to-device or machine-to-machine communication within general computer networks. The most visible and publicly discussed example is the use of radio frequency identification (RFID) tags for improved supply chain management [1,2]. Several large retail chains as well as the US Department o...

Radio frequency identification (RFID) may be used to automatically detect, locate and/or identify objects, making it an ideal candidate for many pervasive computing applications. As RFID technology improves in terms of cost and performance, it is increasingly being explored in a variety of applications, ranging from eldercare through to the smart supply chain. However, while passive UHF RFID ha...

Pervasive Computing technologies can be successfully used in hospital and clinical environments in order to provide smart and enhanced healthcare services and applications. According to this vision, the paper presents an RFID-based application for handling the workflow of patients injected with radioactive substances in a nuclear medicine department. Specifically, the application exploits the R...

In logistic markets there is an increasing use of new Autonomous Co-operation technologies, like RFID or sensor networks [Rie08]. These elements, which are called “Smart-Parts”, are enabled to interact by the appliance of the new technologies (e.g. RFID-chips) in logistic processes, making own decisions without an external control of a superior hierarchic entity. The technologies allow autonomo...

Recently, there is lots research for tangible objects which enables to support users everyday’s life. However, due to the high price of sensors , endusers hesitate to attach such devices to physical objects. Even worth, batteries of embedded devices should despoil the living environment. Therefore, the lowprice system to detect users’ phisical objects without battery is needed. We will propose ...

New forms of interaction are arising closer to the users and embedded in the intelligent environments. In this work we present a contextaware application through Radiofrequency Identification (RFID) offering services to the users in an implicit way. The only required interaction with the system is to wear a little device called tag (smart label). Some of these services such as location, presenc...

Smart item technologies, like RFID and sensor networks, are considered to be the next big step in business process automation [1]. Through automatic and real-time data acquisition, these technologies can benefit a great variety of industries by improving the efficiency of their operations. SAP’s Auto-ID infrastructure enables the integration of RFID and sensor technologies with existing busines...

We present a new vision for smart objects and the Internet of Things wherein mobile robots interact with wirelessly-powered, long-range, ultra-high frequency radio frequency identification (UHF RFID) tags outfitted with sensing capabilities. We explore the technology innovations driving this vision by examining recently-commercialized sensor tags that could be affixed-to or embedded-in objects ...

A form of a novel adaptive antenna system that combines radio frequency identification (RFID) technology, programmable intelligent computer (PIC) microcontroller and reconfigurable beam steering antenna is proposed. Localization and adaptive response are the most challenging issues in smart antenna system. In this research, the localization technique relying on the received signal strength (RSS...

The popularity of Radio Frequency Identification (RFID) has increased in recent years. Although RFID has many benefits over other identification technologies, there are certain situations that can lead to uncertainty about the true location of the tagged object. In this paper we incorporate the knowledge about the operation of an RFID system and its various failure modes, and evidence from the ...
