Abstract:
It is useful to protect residents in a geographical region against hazards and
attacks using a sensor network. Real world sensors for harmful plumes have
limited ranges. If there is insufficient sensing resource to cover whole
geographical regions all the time, mobile sensor coverage is useful. In this
case, we would like to allocate the sensing resources according to the
different threat levels of the subregions (e.g., to give more coverage to more
densely populated subregions). In this talk, I will analyze the information
capture of such threat-based mobile coverage in terms of stochastic event
arrivals and departures and the types of event. Based on the analysis, I will
present the optimization of mobile coverage schedules such that threat-based
coverage is achieved while the information capture is maximized.
Bio:
David Yau obtained the B.Sc. from the Chinese University of Hong Kong (CUHK)
and the M.S. and Ph.D. from the University of Texas at Austin, all in computer
science. He has been on the faculty of Purdue University, West Lafayette,
Indiana, USA since 1997, where he is now Associate Professor of Computer
Science. David received the CAREER award from the U.S. National Science
Foundation. He serves on the editorial board of IEEE/ACM Transactions on
Networking. He serves/has served as vice general chair (2006) and TPC co-chair
(2007) of IEEE Int'l Conf. on Network Protocols (ICNP), and TPC co-chair (2006)
and Steering Committee member (2007--present) of IEEE Int'l Workshop on Quality
of Service (IWQoS). His research interests are in protocol design and
implementation, network security, and wireless/sensor networks.
