Abstract: In sensor networks, there is interplay among sampling density, measurement reliability, confidence in the physical model, scale of cooperation of sensing nodes, and the eventual quality of the scientific inference. Implications for system design, and new applications such as personalized health will be discussed. Radio communications networks typically have stronger models and more standardized desired inferences, but also have problems of how to efficiently manage interactions between heterogeneous non-cooperating radios. In this talk, we compare and contrast the problems in the design of sensor networks and cognitive radios. Particular problems considered are the scale of cooperation required for efficient sensing and multi-hop networking, the tradeoff between model knowledge/sensor reliability and sampling density, and the relative efficiencies of FDMA and frequency sharing.
