Its importance has motivated scientists and researchers to examine the challenges that are slowing its expeditious deployment in various applications. RFID collision is a major challenge imposed by the wireless links shared among a reader and the many tags in the interrogation zone. In most proposed anti-collision algorithms, tags reply randomly to time slots chosen by the reader. Since two or more tags may choose the same slot, this Random Access (RA) causes garbled data at the reader side; therefore, the identification process fails. In this paper, we propose a new anti-collision algorithm that adopts a novel method for eliminating the theory of RA to enhance system efficiency and to reduce both the number of rounds between reader and tag and the number of collided/empty slots over existing algorithms. In this algorithm, tags use modulo function to choose tag owned time slot. Another advantage of this method is that the reader estimates the next frame size and compares it with the previously selected frame sizes that are saved in the reader to ensure there is no redundancy. The performance of the algorithm is simulated and compared with existent ALOHA family algorithms.","PeriodicalId":438738,"journal":{"name":"2014 IEEE International Conference on RFID (IEEE RFID)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127351709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are, however, many unsolved challenges in designing an effective and efficient RFID system for anti-counterfeiting purpose. The first challenge lies in designing a system which is suitable for standard passive RFID tags, especially EPC C1G2 tags, which are widely used in real-world supply chains. These tags cannot afford strong security primitives due to very limited storage and computational capability. The second challenge lies in designing a system which can efficiently handle a increasing number of RFID products. Existing approaches for clone tag detection suffer from performance bottlenecks because a centralized detection server is required in these approaches to record and analyze the traces of all individual products. Thirdly, a practical approach to clone tag detection should work efficiently in real-world RFID systems, where products are moved and processed in batches. To address these challenges, we propose a Batch Clone Detection (BCD) scheme, which is simple, efficient, and practical. It requires only a few bits of storage in RFID tags and no computation on RFID tags, which makes it suitable for standard EPC C1G2 tags. In BCD scheme, the clone tag detection is performed at a batch level, which significantly reduces the storage and computational overheads on the server side.","PeriodicalId":438738,"journal":{"name":"2014 IEEE International Conference on RFID (IEEE RFID)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126682752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking into account a small scale fading channel and the UHF RFID transmission specified by the the EPCglobal protocol a poor communication performance is observed. As the decoding process of the received information is not specified in this protocol, there is a significant potential of increasing the transmission performance with an appropriate decoding. This work will introduce a novel possibility to decode the received information. To match the decoding process with the transmission behavior, it will be shown how the system with a basic decoding scheme performs. Based on these results several modifications, like amplitude threshold, differential decoding and the modification of the used codes will be presented. These modifications take the channel behavior and its characteristic into consideration and lead to a performance gain of 26.2 dB using a certain encoding scheme. These results will be supported by the analysis of the bit error characteristic to demonstrate how the transmission is influenced by the modifications. Note that most modifications presented in this work can be implemented on the RFID reader side. Only the modification of the tag encoding sequence requires a change in the transponder structure.","PeriodicalId":438738,"journal":{"name":"2014 IEEE International Conference on RFID (IEEE RFID)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122290637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the EPCglobal standard which standardizes RFID architectural framework and interfaces, the Electronic Product Code Information System (EPCIS) - the repository in the RFID network - plays a pivotal role in storing dynamic and historical RFID trajectory data, well-tailored to supply chain applications. However, in the IoT era, EPCIS should be capable of storing a large amount of realtime and continuous time-series RFID data in a scalable manner. Therefore, in this paper, we analyze the requirements and current design of EPCIS and report current limitations of SQL-based approaches for IoT applications. To cope with these limitations, we explore a NoSQL-based approach for EPCIS in the IoT and propose a column-family-based data model and customization for Cassandra-based EPCIS. Using real-world implementation, we also conduct a performance comparison between MySQL and Cassandra in different deployment scenarios (i.e., physical and virtual machines). As a result, we show the benefits of using Cassandra datastore for EPCIS in the IoT in terms of response time, throughput, and flexibility.","PeriodicalId":438738,"journal":{"name":"2014 IEEE International Conference on RFID (IEEE RFID)","volume":"889 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127991006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
