Title: New Approaches to Energy-efficient Data Aggregation in Wireless Sensor Networks

Abstract: Wireless Sensor Networks (WSNs) make sensory measurements usually under severe constraints on available energy while performing energy-consuming tasks of data communication, aggregation, and interpretation. Advances in semiconductor technology have enabled ever more computing power for sensors and the cost of computations is substantially lower than that of communication cost in data exchange among sensors. We have recently investigated new approaches, including the use of compressive sensing, to balancing tradeoffs between computation and communication efficiency to reduce the attendant energy dissipation in common data processing tasks in WSNs. This talk will focus on strategies to achieve better computation and communication performance in data aggregation and processing. The approaches show significant improvement over existing methods in terms of energy efficiency and other performance criteria. Adaptive and spatio-temporal methods for performing data aggregation will be described along with simulation results demonstratingimproved performance. Other related work will also be described.

Ansari教授的简历:

Rashid Ansari received the Ph.D. degree in electrical engineering and computer science from Princeton University, Princeton, NJ, in 1981. He is currently Professor and Head in the Department of Electrical and Computer Engineering at the University of Illinois at Chicago (UIC). Before joining UIC he served as a Research Scientist at Bell Communications Research and on the faculty of Electrical Engineering at University of Pennsylvania. His research interests are in the general areas of signal processing and communications, with recent focus on image and video analysis, multimedia communication, and medical imaging. In the past he served as Associate Editor of the IEEE Transactions on Image Processing, IEEE Signal Processing Letters, and IEEE Transactions on Circuits and Systems. He was a member of the editorial board of the Journal of Visual Communication and Image Representation. He has served as a member of the Digital Signal Processing Technical Committee of the IEEE Circuits and Systems Society and a member of the Image, Video, and Multidimensional Signal Processing Technical Committee. He was a member of the organizing and program committees of several past IEEE conferences. He served on the organizing and executive committees of the Visual Communication & Image Processing (VCIP) conferences and was General Chair of the 1996 VCIP Conference. He was elected a Fellow of the IEEE in 1999.
