  • Opportunistic Spectrum Access via Dynamic Resource Allocation

    Mon, Jun 09, 2008 @ 11:00 AM - 12:00 PM

    University of Michigan Abstract:
    Recent advances in software defined radio and cognitive radio have given
    wireless devices the ability and opportunity to dynamically access
    spectrum, thereby potentially significantly improving spectrum efficiency
    and user performance. With this opportunity comes the challenge of
    effective resource allocation between probing/sensing channels to find out
    their availability and quality, and deciding which channels to use for
    data transmission.
    In this talk we will discuss some of the unique technical constraints
    imposed by dynamic and opportunistic spectrum access, and their
    implications on mathematical modeling. We then present two specific
    formulations within such a multi-channel dynamic access context, one using
    a stochastic optimization framework and the other using a competitive
    analysis framework, respectively. We will show the structural properties
    of the optimal policies obtained using such formulations along with
    numerical results.
    Bio:
    Mingyan Liu is an Associate Professor in EECS at the University of
    Michigan. She received her Ph.D. degree from the University of Maryland,
    College Park in 2000. Her research interests are in performance modeling,
    analysis, energy-efficiency, and resource allocation issues in cognitive
    radio networks, wireless mobile ad-hoc networks, wireless sensor networks,
    and terrestrial satellite hybrid networks. She was the recipient of a 2002
    NSF CAREER Award and the University of Michigan Elizabeth C. Crosby
    Research Award in 2003.
