Radio frequency identification (RFID) is a wireless communication technology that provides automatic identification and data collection. In RFID systems with a large number of tags, many tags respond to the reader at the same time. Thus, enhanced anti-collision algorithms are required to have a fast multiple tag identification process. Anti-collision(More)
Radio frequency identification (RFID) suffers from collisions when multiple tags respond in the same time. This paper presents Query Tree ALOHA (QTA) anti collision algorithm, improved by using a new tag estimation technique based on signal strength. In addition, by using this technique it is possible to detect when two tags remain in the identification(More)
Signal strength (SS) based tag estimation significantly improves the accuracy and speed of RFID tag interrogation. In [1], SS estimation was applied to a Manchester based RFID system and a formula for the lower bound on number of tags was derived. This paper analytically extends this analysis to a comprehensive list of encoding formats including all those(More)

In this paper we present a new Smart Online Vehicle Tracking System for Security Applications (AMOTSSA) and we describe how it can be modelled and implemented as a Big data application. In order to model AMOTSSA as a big data application, we argue our design choices that meets its specific data and processing needs and we present a set of data analytic(More)
High performance RFID anti-collision systems require accurate information on the number of tags left in the interrogation zone. Signal strength (SS) based tag estimation was shown to be an accurate and effective method to speed up RFID tag interrogation [1–2]. SS estimation first shown to work in Manchester based RFID system [1], was analytically(More)
