ABSTRACT:

Many current applications relevant to security and defense involve some form of process detection. This talk will formulate several problems related to the kinds of detection problems sensor networks can solve in cyber, physical, and social environments, with specific attention being paid to tracking behaviors over space and time. We show that there are general Nyquist-like sampling results that are related to a phase transition from polynomial to exponential growth in the number of possible associations of sensor observations. Concrete examples and outlines of proofs will be given. Papers describing details of this body of work can be found at www.pqsnet.net.

Reception to follow in 301 Coordinated Science Laboratory.
