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.


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.
