Parameter Scheme

Radio Frequency Identification is an Automatic Identification Technology. RFID system typically consists of a reader and a number of tags. When more than one tag send signal to reader at the same time, reader will not identify any one. This is called collision. The information of collision is regarded as uselessness in the conventional algorithms. But in fact, useful information can be extracted from the collision and the reading efficiency can be improved. In this paper, tags use BIBD(16,4,1) blocks instead of RN16, the reader analyses the collision information based on the characteristics of BIBD and makes valid recognition even when more than one tag have been detected in same time slot. The theoretical and simulation results show that the proposed algorithm can improve the reading efficiency by 100% than that of the conventional Q algorithm. Furthermore, the proposed scheme changes little to the existing standard, easy to implement and compatible for EPC Global Code.

Binary Tree Search

Slot partial competitive (SPC) anti-collision algorithm is based on the ISO/IEC18000-6C UHF radio frequency identification (RFID) standard, which introduces dynamic binary tree search technology into the competitive collision avoidance mechanism. Moreover, the SPC algorithm applies the specific technologies to idle slots and collision slots. This paper proposes a segment slot partial competitive (SSPC) anti-collision algorithm based on the SPC, and introduce the segment algorithm. The performances of the dynamic binary tree search, the SPC algorithm and the SSPC algorithm are compared via simulation experiments. Simulation results indicate that the SSPC algorithm is improved significantly.

In the traditional RFID (Radio Frequency IDentification) system, a secure wired channel communication is used between the reader and the server. The newly produced mobile RFID system is different from the traditional RFID system, the communication between the reader and the server is based on a wireless channel, and the authentication protocol is suitable for traditional RFID systems, but it cannot be used in mobile RFID systems. To solve this problem, a mutual authentication protocol MSB (Most Significant Bit) for super lightweight mobile radio frequency identification system is proposed based on bit replacement operation. MSB is a bitwise operation to encrypt information and reduce the computational load of communication entities. Label, readers, and servers authenticate first and then communicate, MSB may be used to resistant to common attacks. The security analysis of the protocol shows that the protocol has high security properties, the performance analysis of the protocol shows that the protocol has the characteristics of low computational complexity, the formal analysis of the protocol based on GNY logic Gong et al. (1990) provides a rigorous reasoning proof process for the protocol.

The Impact

Radio frequency identification (RFID) is a rapidly evolving technology for automatic identification and data capture of products. One of the barriers to the adoption of RFID by organizations is difficulty in assessing the potential return on investment (ROI). Much of the research and analyses to date of ROI in implementing RFID technology have focused on the benefits to the retailer. There is a lack of a good understanding of the impact of RFID at upper echelons of the supply chain. In this paper, we present a framework and models for assessing the value of RFID implementation by tier-one suppliers to major retailers. We also discuss our real-life application of this framework to one of Wal-Mart’s top 100 suppliers

This paper discourses about a very general problem that occurs in everyday life. In many universities, students are at risk of misplacement or theft of valuables. So, to avoid such mis happening, the development of security system was designed for providing the safety of university student belongings. The proposed security system contains some common information, methodology, schematics and some details related to technical field that is employed into the system, such as RFID (Radio Frequency Identification) and barcode readers along with the design of the established system. For the functioning of the system in a most effectively manner, assumptions with some specific requirements that is needed to be met are encompassed in this paper

Frequency Identification

Radio Frequency Identification (RFID) is a non-contact, automatic identification technology. Through its radio frequency signal, RFID offers automatic target recognition and access to relevant and without human intervention identification of work is made. RFID can work in various environments. It can identify fast moving objects and is capable of identifying multiple tags, in a rapid and convenient operation. Since the 1990s, RFID technology has been widely used in commercial, logistics, property management and other fields, but interest towards potential application to the needs of the tourism industry only began in recent years.

Technical Factors

Australian hospitals had begun exploring Radio Frequency Identification, a wireless automatic identification and data capture technology for improving the quality of their services towards the end of 2000s. After many an unsuccessful pilots, a breakthrough for large hospitals came in 2010, with a key learning rendered by a large regional hospital that not only experimented with the technology, but also have made it all pervasive in their operations. In this chapter, we present the case study, through an innovation translation perspective, focusing on the socio-technical factors captured through elements of Actor-Network Theory.
