AURA: Design of Dense RFID Systems for Indexing in the Physical World across Space, Time, and Human Experience

Today, individuals have to function in complex environments, with increasing demands on their time and attention. The tasks in the physical world commonly make use of information centric processes, such as search and explore of physical objects. We envision an informational environment that supports such searches in the physical world. This environment must be transparently embedded with relevant information and should be accessible from small form-factor devices, such as PDAs and cell-phones. In other words, this environment needs to be non-obtrusive and should be organically integrated to individuals’ daily experiences. RFID technology is a natural platform for addressing the issue of information embeddedness. Indexing in the physical world across space and time using passive and limited-capability tags require innovative data management research at multiple levels. The cost of random access to a large data structure from a single tag necessitate research onto efficient associative encoding of symbolic and numeric logical search attributes (e.g., color, time, popularity). We also do research into enabling distributed data structures that can resolve queries for remote objects, by accessing only local tags, within the specified radio range. In particular, we introduce the concept of aura which encodes object-memory into the environment. Interrogator-mediated aura propagation techniques, in conjunction with spatio-temporal metadata embedded in the RFID tags, are exploited for locating matching objects through a chaining process. Furthermore, in order tackle the issue of unreliable reads and writes, we introduce efficient, yet effective redundancy mechanisms in aura management.

Short bio

K. Selcuk Candan is a Professor of Computer Science and Engineering at the School of Computing, Informatics, and Decision Science Engineering at the Arizona State University and is leading the EmitLab research group. He joined the department in August 1997, after receiving his Ph.D. from the Computer Science Department at the University of Maryland at College Park.

Prof. Candan's primary research interest is in the area of management of non-traditional, heterogeneous, and imprecise (such as multimedia, web, and scientific) data.  His various research projects in this domain are funded by diverse sources, including the National Science Foundation, Department of Defense, Mellon Foundation, and DES/RSA (Rehabilitation Services Administration). He has published over 140 articles and many book chapters. He has also authored 9 patents. Recently, he co-authored a book titled "Data Management for Multimedia Retrieval" for the Cambridge University Press and co-edited "New Frontiers in Information and Software as Services: Service and Application Design Challenges in the Cloud" for Springer.

Prof. Candan served an editorial board member of one of the most respected database journals, the Very Large Databases (VLDB) journal. He is currently an associate editor for the IEEE Transactions on Multimedia and the Journal of Multimedia. He has served in the organization and program committees of various conferences. In 2006, he served as an organization committee member for SIGMOD'06, the flagship database conference of the ACM and one of the best conferences in the area of management of data. In 2008, he served as a PC Chair for another leading, flagship conference of the ACM, this time focusing on multimedia research (MM'08). More recently, he served as a program committee group leader for ACM SIGMOD’10. He also served in the review board of the Proceedings of the VLDB Endowment (PVLDB). In 2011, he served in the Executive Committee of ACM SIGMM.

In 2010, he was a program co-chair for ACM CIVR'10 conference and a program group leader for ACM SIGMOD'10. In 2011, he is serving as a general co-chair for the ACM MM'11 conference. In 2012, he served as a general co-chair for ACM SIGMOD'12. In 2015, he will serve as a general co-chair for IEEE International Conference on Cloud Engineering (IC2E'15).

He is a member of the Executive Committee of ACM SIGMOD and an ACM Distinguished Scientist.
