  1. RFID Sensor Networks The research team of professor Cheng Lianglun The Faculty of Automation Guangdong University of Technology December 15, 2010

  2. RFID Can tell “Who is it”: the identity of the tagged items The ability to track the location of the tagged items Excellent performance in various complicated environment, e.g., high speed mobility, anti-pollution, etc. However Limited communication range Can not tell “how is it” Wireless sensor network self-configuring, self-networking, self diagnosing and self-healing Can tell “how is it” by various sensors Can extend the communication range by multiple hops. Our work RFID Sensor Networks by exploiting the advantages of both RFID and Wireless sensor networks Kernel technologies in USN (ubiquitous sensor network ) Motivation

  3. RFID Sensor Networks • RFID Sensor network • Heterogeneous • Architecture A • A Mix of tags and sensor nodes • Sensor nodes transmit information to the sink nodes through multi-hops • Architecture B • Smart node: sensing part, RFID reader, RF transceiver • Smart nodes read fewer tags around • Seamless • RFID and sensor nodes are integrated for special missions • Data aggregation from both tags and sensor nodes • Common system architecture • SU: sensor nodes or RFID readers • AU: automatic response unit • GW: gather information from SUs and forward control commands to AUs • Edge Server: distributed for data (or event) processing , aggregation and real-time system controlling • Central Controller: overall control and command fig.A fig.B

  4. Architecture and protocols in RFID sensor network architecture, design of the intelligent nodes, scalable routing protocol, efficient reservation-based MAC protocol, etc. Embedded moving database (EMDB) RFID tag anti-collision algorithm, strategy of data safe aggregation distributed and hierarchicaldatabase management system, the essential technologies of EMDB Node synchronization and localization Strategy of node synchronization based on Kuramoto model, node localization and tracking algorithm RFID middleware Integration of RFID wireless sensor network and information resource network Ability of real-time data collection, precise control of bottom devices, etc. Security & Privacy Research and application of stream cipher encryption algorithms Hardware realization of stream cipher encryption algorithms Major researches in RFID sensor networks
