Abstract
We consider an exponential server queue accessed by many different flows. It
is assumed that the source and destination information of each
flow is available in the packet header. We compute upper and lower bounds
on the sum timing capacity of this channel.
We also discuss the implications of this result for a single flow, where
packets can be "colored" to distinguish them, and the amount of
covert information that can be transmitted over this channel in the
presence of eavesdroppers who are allowed to observe the packet headers.
We will also discuss the role of the scheduling discipline at the server
on the amount of covert information that can be conveyed.
Biography
R. Srikant received his B.Tech. from the Indian Institute of Technology,
Madras in 1985, his M.S. and Ph.D. from the University of Illinois in 1988
and 1991, respectively, all in Electrical Engineering. He was a Member of
Technical Staff at AT&T Bell Laboratories from 1991 to 1995. He is
currently with the University of Illinois, where he is an Associate
Professor in the Department of General Engineering, a Research Associate
Professor in the Coordinated Science Lab and an Affiliate in the
Department of Electrical and Computer Engineering.
He was an associate editor of Automatica, and is currently on the
editorial boards of the IEEE/ACM Transactions on Networking and IEEE
Transactions on Automatic Control. He was the chair of the 2002 IEEE
Computer Communications Workshop in Santa Fe, NM. He received an NSF
CAREER award in 1997. His research interests include communication
networks, stochastic processes, queueing theory, information theory,
control theory and game theory.
