© 2011 ETRI Journal, Volume 33, Number 3, June 2011 With the introduction of the new generation RFID technology, EPCglobal Class-1 Generation-2, there is considerable interest in improving the performance of the framed slotted Aloha (FSA)-based tag collision arbitration protocol. We suggest a novel time-optimal anti-collision algorithm for the FSA protocol. Our performance evaluation demonstrat...

The passive ultra-high frequency (UHF) RFID is being increasingly employed in various applications. The low-cost, long range and high data rate features making it an outstanding choice in contactless identification. Although, passive tag performance is likely to be affected by water and metal, tag packages and special tag designs are developed to minimize the effect of the environment. Tag perf...

Lately, the ISO fixed on UHF Gen2 as one of the standard protocols for RFID, called ISO 18000-6 C, along with ISO 18000-6 A/B. It means that the RFID system should provide the multi-protocol support for tag identification and a proper protocol should be chosen depending on the situation. The tag anti-collision algorithm is one of the important research issues to be on top of the protocol’s perf...

The GOLD reference system for active RFID is a reader and a tag designed according to the latest version of the ISO 18000-7 standard for active RFID. Conformance and interoperability testing of different commercial readers and tags, require a stimulus from a common source that completely conforms to the standard, which is also programmable allowing alteration of the signal parameters within the...

In RFID systems addressing security issues, many authentication techniques require the tag to keep some sort of synchronization with the reader. In particular, this is true in those proposals that leverage hash chains. When the reader and the tag get de-synchronized, possibly by an attacker, this paves the way to several denial of service (DoS) attacks, as well as threatening privacy (e.g., via...

The employment of mobile readers (or phone collaborated with a Radio frequency identification (RFID) reader) opens novel application for RFID technology. In particular, an tag search system has been designed to find particular in group tags using reader. Unfortunately, privacy infringement and availability issues the have not adequately addressed date. this paper, we propose protocol that will ...

The rapid proliferation of Radio Frequency IDentification (RFID) systems realizes integration of physical world with the cyber ones. One of the most promising is the Internet of Things (IoT), a vision in which the Internet extends into our daily activities through wireless networks of uniquely identifiable objects. Given that modern RFID systems are being deployed in large-scale for different a...

In this article, we compare the different types of batterypowered RFID tags that are available today and explore several emerging wireless standards that are candidates for active RFID tagging. We also present an active RFID platform we have developed and a supply chain application implemented on that platform. INTRODUCTION Passive (battery-less) RFID technology has been the primary candidate f...

The RFID technology is affected by the reader-to-reader collision problem. Several studies propose anti-collision protocols. A high throughput adaptation protocol based on time division is Colorwave. A known mechanism, already applied to another time division protocol to improve its performance, is the introduction of a probability factor in the collision resolution routine. In this work, the e...
