Lessons on the Placement, Autonomy, and Fusion of Wireless Sensor Data

  • CS Auditorium (#127), Goldberg Computer Science Building, Dalhousie University 6050 University Avenue Halifax Canada (map)

Speaker: Ioanis Nikolaidis, (University of Alberta)


We present a collection of lessons learned from the deployment of real world wireless sensor network applications and the corresponding research issues. Our experiences are based on our work with the SmartCondo environment and from residential building sensing. Namely, we will consider: sensor placement, seen as a variety of the "coverage" problem; sensor autonomy, seen from the niche of thermoelectric energy harvesting; and sensor "fusion" from combinations of anonymous and eponymous sensing. We will also address to some extent the problem of sensor data outages -- a phenomenon not uncommon in real environments -- caused by energy depletion or by the unpredictable nature of the wireless propagation environment. We will highlight previous as well as ongoing work to characterize and mitigate such outages.

Brief Bio:

Ioanis Nikolaidis (BSc U. Patras 1989, MSc Georgia Tech 1991, PhD Georgia Tech 1994) worked as a Research Scientist for ECRC GmbH (1994-1996) and joined the Computing Science Department in 1997, where he is (since 2008) a Full Professor and, currently, the Associate Chair (Research). He is also an Adjunct Professor with the Department of Occupational Therapy. He supervised several PhD, MSc students, as well as undergraduate and high school trainees and has published more than a hundred papers and chapters in refereed journals, conferences, and books. Dr. Nikolaidis is conducting research in the area of data networking protocols, protocol performance, and wireless sensor networks. He served as Area Editor for Computer Networks, Elsevier ('00-'10), and as a long standing Editor ('99-'13) and Editor-in-Chief ('07-'09) for the IEEE Network magazine. He has co-chaired CNSR 2011, ADHOC-NOW 2004 & 2010, and co-organized SSS 2015. He has served as technical program committee member and reviewer for numerous conferences and journals, as well as a reviewer or panel member for the following funding agencies: NSERC, NSF, Ontario Centers of Excellence, FWF/START (Austria), NTU/IntelliSys (Singapore), NWO (Holland). He co-edited the book "Building Sensor Networks: From Design to Applications" (CRC Press). He is the co-recipient of the best paper award of CNSR 2011, recipient of the best paper presentation of ADHOC-NOW 2012, co-recipient of the University of Alberta Teaching Unit Award as part of the the SmartCondo teaching team, and recipient of the best paper award of SMARTGREENS 2014. He is a member of IEEE and a lifetime member of ACM.
