Title: Stochastic Control of Heterogeneous Networks
When: Monday April 14th, 10am MDT, 1600-1730 UTC
Where: Mosaic Venue (off of the NCSA Lobby)
Speaker: Prof. Eytan Modiano (Massachusetts Institute of Technology)
In this talk we will describe algorithms for resource allocation in
networks that include wirless, satellite and wired (e.g., optical)
consider a network with stochastic traffic and randomly varying channel
In the first part of the talk we address the joint problem of flow control,
and scheduling in a heterogeneous network subject to quality of service
requirements. In particular, we will describe a dynamic control strategy that
maximizes the sum utility in the network, and can be used to achieve a wide
service objectives. This scheduling algorithm is centralized in its nature and
requires the solution of a complex optimization problem. Hence, in the
of the talk we will discuss distributed algorithms for solving the optimal
scheduling problem with low computation and communication complexity. In
particular, we will describe randomized algorithms for scheduling and
routing in a
wireless network that maximize network throughput with communication and
requirements that are comparable to those of existing algorithms that can only
guarantee 50% throughput.
Eytan Modiano received his B.S. degree in Electrical Engineering and Computer
Science from the University of Connecticut at Storrs in 1986 and his M.S.
degrees, both in Electrical Engineering, from the University of Maryland,
Park, MD, in 1989 and 1992 respectively. He was a Naval Research
between 1987 and 1992 and a National Research Council Post Doctoral Fellow
1992-1993. Between 1993 and 1999 he was with MIT Lincoln Laboratory where
the project leader for MIT Lincoln Laboratory's Next Generation Internet (NGI)
project. Since 1999 he has been on the faculty at MIT; where he is
Associate Professor. His research is on communication networks and
emphasis on satellite, wireless, and optical networks.
He is currently an Associate Editor for IEEE Transactions on Information
International Journal of Satellite Communications, and for IEEE/ACM
Networking. He had served as a guest editor for IEEE JSAC special issue on WDM
network architectures; the Computer Networks Journal special issue on Broadband
Internet Access; the Journal of Communications and Networks special issue on
Wireless Ad-Hoc Networks; and for IEEE Journal of Lightwave Technology
issue on Optical Networks. He was the Technical Program co-chair
for Wiopt 2006,
IEEE Infocom 2007, and ACM MobiHoc 2007.
