A sensor network is a spatia-temporal sampling device with a wireless communications infrastructure. In this talk, after a short overview of the Center on Mobile Information and Communication Systems (http://www.mics.org), we will address the following questions: I . The spatio-temporal structure of distributed signals, with an emphasis on the physics behind the signals, and results on sampling 2. The interaction of distributed source compression and transmission, with a particular focus on joint source-channel coding 3. Some applications in environmental monitoring, like for example tomographic measurements This is joint work with T.Ajdler, B.Beferull-Lozano,, H.Dubois-Ferriere, R.Konsbruck (EPFL), RCristescu (Caltech), P.L.Dragotti (Imperial) and M.Gastpar (UC Berkeley). The work is sponsored by the Center on Mobile Information and Communication Systems (www.mics.org), funded by the Swiss National Science Foundation.
