Internet of Things (IoT) is rather prevalent in many manufacturing and smart city applications, while localization is a premise for many other processes, varying from ordering objects in manufacturing lines to locating books on bookshelves. Radio Frequency Identification (RFID) based localization is of great interest in many IoT applications. Synthetic aperture RFID, due to its anti-noise capability...
With the development of RFID technology, RFID based applications are wildly used in various fields, especially in supply chain automation. EPC (Electronic Product Code) Information Service, which takes a basic and key role in EPC network system, has become a hot research spot. How to establish highly efficient and extensible distributed EPCIS repositories is an important problem to be resolved. This...
Radio Frequency Identification (RFID) is increasingly being used and has been successfully applied to various areas, such as retail, pharmaceutical and pet tracking. Despite its obvious popularity, RFID data reliability is always the problem which should be addressed. In this paper, a data cleaning technique based on time and location is proposed to improve RFID reading's reliability. For temporal...
Internet of Things is a key component of next generation information technology. And the key of Internet of Things is RFID. Now Internet of Things brings new requirements to handheld UHF RFID reader. This paper proposed a complete solution of handheld UHF RFID reader based on AS3991 and AM3517 for The Internet of Things. This reader uses AS3991 UHF RFID reader chip , which conforms to ISO18000-6C...
In this paper, an active RFID real time location system based on fingerprint algorithm was founded. Two typical scenarios were chosen including ideal environment and complex environment to test the performance of the location system. Certain parameters were considered while evaluate the performance of the location system. Finally, the result shows the performance in different conditions.
In the supply chain management,the warehouse management is an important component.It is necessary to improve storage management efficiency and reduce operational costs and error rates.Therefore,it needs a new logistics information technology to replace the traditional mode of storage operation. RFID (radio frequency identification) and WSN (Wireless Sensor Network) technology can precisely solve this...
With the growing success of the mobile computing devices, such as laptop computer, third generation mobile phone, personal digital assistant, many current and emerging distributed applications present challenging problems to the RFID complex event processing architecture. The traditional architecture of central complex event processing should be reconstructed and the new architecture should show a...
As RFID technology continues to evolve and the complexity of enterprise-class applications increased, the industry has become aware that, testing, analysis, and verify feasibility and reliability of speech is a must before putting RFID system into actual use, based on which we propose optimization strategies to meet the enterprise application standard or baseline, and reduce the maintenance cost of...
RFID device management and monitoring is an indispensable part of RFID middleware technology, this paper presents an implementation of device management and monitoring in reconfigurable middleware, which consists mainly of two tasks: one is managing the RFID hardware and software devices, and the other is monitoring the running status of RFID software and hardware devices. Through management, we can...
UHF RFID portal, usually composed by two or three antennas which connect to one reader. However, RFID system designers often feel puzzle about the antenna deployment since they have no idea of how high or which angle the antenna should be or how many antennas should be deployed. An antenna deployment optimization and evaluation method was proposed in this paper, which can guide the designer to optimize...
With the widespread usage of RFID technology, complex event processing becomes a very important part in RIFD system. In order to improve the working efficiency of the system and provide semantic results to the enterprise application, it is necessary to transform the raw RFID data into meaningful events. However the RFID data stream has unique features compared with the traditional data stream such...
RFID middleware plays an important role in Enterprise Applications such as integrating heterogeneous devices, processing data and events, providing uniform application interface and so on. However, some problems RFID middleware developers have to face are how to specify the quality of service for high level applications, how to transmit the RFID data efficiently, and how to consist the abilities of...
This paper investigates how the performance factors affect RFID (Radio Frequency Identification) system performance. We focus on the following parameters: tag placement, angle of reader antenna and conveyor speed. We use commercial RFID reader and tags in experiments and DOE methodology to access the effect of different factors. Experiment result shows that tag placement, angle of reader antenna and...
Considering the multi-reader deployment in large scale RFID implementation, readers are not working independently but cooperate with each other in a certain context, thus they form a reader network. Lots of researches have been done about the reader collision problem, while research for reader coordination is still needed. A RFID reader coordination model is introduced, which provides a monitoring...
RFID complex event processing technology is the key point of RFID researching in these years. For the trend of great network application of RFID, this paper presents an RFID complex event processing model according to the features of RFID data and the disadvantage of the current models. Besides, the application in real scenario is also discussed.
