Abstract:

Next-generation wireless networks are expected to provide quality of
service (QoS) guarantees. In this talk, I will present our recently
developed theory, called RED theory, for QoS provisioning in wireless
networks. The RED theory is used to quantify the relationship among data
rate (R), packet error probability (E), and delay bound (D), under the
interaction between the link layer and the physical layer. Our results
provide important insights about optimal rate control policy for joint
link layer and physical layer design; the proposed RED Pareto surface
represents a major step toward deriving the probabilistic
delay-constrained channel capacity of fading channels, which is an
unsolved problem in information theory.

from Carnegie Mellon University, Pittsburgh, PA, in 2003. Since 2003, he
has been on the faculty of Electrical and Computer Engineering Department
at University of Florida, Gainesville, FL, where he is currently Associate
Professor. His research interests are in the areas of networking,
communications, video coding, image processing, computer vision, signal
processing, and machine learning.

He received University of Florida Research Foundation Professorship Award
in 2009, AFOSR Young Investigator Program (YIP) Award in 2008, ONR Young
Investigator Program (YIP) Award in 2008, NSF CAREER award in 2007, the
IEEE Circuits and Systems for Video Technology (CSVT) Transactions Best
Paper Award for Year 2001, and the Best Paper Award in International
Conference on Quality of Service in Heterogeneous Wired/Wireless Networks
(QShine) 2006. Currently, he serves as an Associate Editor for IEEE
Transactions on Wireless Communications, IEEE Transactions on Circuits and
Systems for Video Technology, and International Journal of Ad Hoc and
Ubiquitous Computing. He was the founding Editor-in-Chief of Journal of
Advances in Multimedia between 2006 and 2008, and an Associate Editor for
IEEE Transactions on Vehicular Technology between 2004 and 2007. He is
also a guest-editor for IEEE Journal on Selected Areas in Communications
(JSAC), Special Issue on Cross-layer Optimized Wireless Multimedia
Communications. He will serve as Technical Program Committee (TPC) Chair
for IEEE INFOCOM 2012, and has served as TPC Chair for IEEE International
Conference on Communications (ICC 2008), Signal Processing for
Communications Symposium. He serves as Chair for the Award Committee,
