Sensor networking is an emerging technology that promises an
unprecedented ability to monitor the physical world via a spatially
distributed network of small and inexpensive wireless sensor nodes.
The nodes can measure the physical environment with a wide variety of
sensors, including acoustic, seismic, thermal, and infrared. While the
practically unlimited range of applications of sensor networks is
quite evident, our current understanding of their design and
management is far from complete. Because sensor networks collect data
in a spatially distributed fashion, statistical inference problems in
sensor networks present a distinct new challenge. In addition to
common issues such as signal-to-noise and sampling considerations,
limited energy resources place a very high cost on the sharing of data
via wireless communications. Consequently, energy efficient methods
for processing and communicating information play a central role in
the theory and practice of sensor networks. This talk will describe
imaging using wireless sensor networks, and discuss how recently
proposed compressed sensing schemes may be very advantageous in such
