Abstract:




FRESCO is an interdisciplinary project driven by the challenging long-standing
problem of optimizing performance of wireless networks under changing operating
conditions. A new experimental design called a locating array is introduced to
efficiently identify significant factors and low-order interactions of factors
when the number of factors is massive.  Profile-driven regression is a  hybrid
regression methodology to address the issues in non-linear modelling through
the use of profiling. The methodology is applied to derive models from a
stochastic simulation of a mobile ad hoc network.  Self-tuning techniques are
developed to decide when and what localized measurements are needed in the
network to drive the real-time statistical monitoring, model evolution, and
adaptive control to optimize network performance as conditions change.




Bio:



Violet R. Syrotiuk earned her Ph.D. in Computer Science from the University of
Waterloo (Canada) in 1992. She joined Arizona State University in 2002 and is
currently an Associate Professor of Computer Science and Engineering. Dr.
Syrotiuk's research has been supported by the U.S. National Science Foundation,
Los Alamos National Laboratory,  Defence Science and Technology Organisation
(Australia), Architecture Technology Corp., Raytheon Co., and General Dynamics.
She serves on the Editorial Board of Computer Networks and the International
Journal of Communication Systems, and on the Technical Program Committee of
several major conferences including Mobicom, Mobihoc, and Infocom. In 2008, she
is a TPC Co-Chair of ACM MSWiM. Her research interests include a wide variety
of topics in multi-hop wireless networks.
