EPC-Based Efficient Tag Selection in RFID Systems

Tag-selection problem, which selects a set of wanted tags from a tag population, is vital for boosting efficiencies of the real-time applications in RFID systems. However, prior arts for the problem can not be applied to RFID systems directly, given that they either require additional computing functions implemented in tag’s chips or require a time-consuming pre-process with a large communication cost. This paper studies the tag-selection problem and propose an efficient Electronic Product Code (EPC)-based tag selection method with theoretical analysis. In particular, firstly, we prove a nontrivial lower bound of communication overhead for a protocol which is capable of solving the tag-selection problem. Secondly, we propose an efficient protocol, denoted by TagSP, which only uses the “select” command (a mandatory command that all RFID tags shall support) and EPC. The proposed TagSP can be applied directly into off-the-shelf RFID systems with a communication overhead close to the lower bound. Extensive simulations are conducted and the simulation results show TagSP’s superiority compared with existing protocols.

RFID Characteristics Test as Business Needs at Logistic Companies in Indonesia

In embedded RFID chips for storing records or data, such as Electronic Product Code one of them using barcode, in tag. Tags have functions to be able to transmit data for readable readers or stationary readers. using radio transmission technology to read data in tags. Each computer in the same system network can share and track data, regardless of where the item is searched for within the scope of the marked or restricted area. Available information may include item code, item date, delivery date, and item price. This study presents a framework based on RFID Proxied Technology Characteristics Real Time Data Processing, Continuous Data Tracking and Discrete Data, and Reuse and explores its relationship with Business Needs. The observed populations are supervisors and managers working in logistic companies taken cross section obtained from a number of logistics companies incorporated in the Indonesian Logistics Association (ALI) in 2015. Sampling is done using convenience sampling method (convenience sampling method) because the population of respondents working in logistics companies in Indonesia is not known with certainty. This research can contribute to how users can select and measure RFID technology from their characteristics so that the application of RFID systems and technology becomes an added value for the company not just as a complementary technology only.

A Novel Method to Evaluate the RFID System Reliability

The experimental results show that the proposed model can evaluate the reliability of RFID system easily and quickly in different application scenarios.

Fast Composite Counting in RFID Systems

Counting the number of tags is a fundamental issue and has a wide range of applications in RFID systems. Most existing protocols, however, only apply to the scenario where a single reader counts the number of tags covered by its radio, or at most the union of tags covered by multiple readers. They are unable to achieve more complex counting objectives, i.e., counting the number of tags in a composite set expression such as $(S_{1} \bigcup S_{2}) - (S_{3} \bigcap S_{4})$ . This type of counting has realistic significance as it provides more diversity than existing counting scenario, and can be applied in various applications. We formally introduce the RFID composite counting problem, which aims at counting the tags in an arbitrary set expression and obtain its strong lower bounds on the communication cost. We then propose a generic Composite Counting Framework (CCF) that provides estimates for any set expression with desired accuracy. The communication cost of CCF is proved to be within a small factor from the optimal. We build a prototype system for CCF using USRP software defined radio and Intel WISP computational tags. Also, extensive simulations are conducted to evaluate the performance of CCF. The experimental results show that CCF is generic, accurate and time-efficient.

The simulation results showed that the amount of transmitted data in proposed algorithm was obviously less than those in the other two traditional algorithms with the number of tags and their bytes increasing. Consequently, the performance of the proposed algorithm is much better than that of the traditional anti-collision binary algorithm.

EPC Network 기반 RFID 응용 시스템의 성능 향상을 위한 EPCIS 주소별 그룹 질의 기법

오늘날 RFID 응용 시스템은 점차 발전되고 물류, 유통, 항만 그리고 제조 등 다양한 산업분야에서 적용되고 있다. RFID 응용 시스템 개발을 위한 국제 표준으로 EPCglobal 에서는 EPC Network 아키텍처를 제시하고 있다. EPC Network 아키텍처를 통해 개체의 고유정보(master information) 및 이력정보(event information)를 수집해야 한다. 그러나 개체의 고유정보 및 이력정보를 저장하고 있는 EPCIS의 경우는 수집된 EPC와 각 개체가 가지는 이력정보의 수에 의존적으로 통신 횟수가 증가하며, 개별적인 EPC에 대한 처리로 인해 동일한 EPCIS와 여러 번 통신해야 하는 문제점이 존재한다. 이러한 문제점은 EPCIS와의 통신시간의 증가로 인해 RFID 응용 시스템의 성능을 저하 시키게 된다. 따라서 본 논문에서는 EPCIS와의 통신 시간을 감소시키기 위하여 동일한 EPCIS와의 통신을 제거하는 EPCIS 주소별 그룹 질의 기법을 제시한다. 또한, 본 논문에서 제시한 기법을 적용하고 실제 EPC Network 환경을 구축하고 다양한 실험을 통하여 효용성을 검증하였으며 EPCIS의 통신 시간이 최대 99% 감소하는 것을 확인할 수 있었다. These days RFID application has been developed rapidly. It has been applied to many business areas such as logistics and supply chains. The Electronic Product Code (EPC) Network Architecture, an open global standard, is proposed by EPCglobal for developing RFID enabled systems. People who want to obtain the product information which are master information and event information have to apply with EPC Network Architecture. However, EPCIS which has master information and event information has to be accessed base on each EPC. Therefore, there is lots of duplicate accessing to EPCIS because RFID application has to access the same EPCIS over again which makes all performance down in EPC Network. This paper proposes how to reduce access times to EPCIS using EPC grouping based on EPCIS address. We build EPC Network environment to experiment about performance of RFID application system and we prove the improvement of EPC Network. Our result shows the reducing the EPCIS communication time by maximum 99 percentages.

In order to build up the ubiquitous computer environment, there are many researches on automatic identification, sensor networks, and home networks etc. EPCIS (EPC Information Services), which is proposed by EPCglobal, is a standard on the repository managing tag data that is needed to develop RFID application system. In this paper, the EPCIS repository is designed and implemented. It is able to search the object dependent upon general object recognition and environment information variation. And sensor data, which is also massive data and is changed with position, is integrated into RFID data in the system. By doing so, it is possible to do the convergence managements of object recognition with variations of USN (Ubiquitous Sensor Network) environment.
