COMPASS - A COllaborative Multiscale Processing and Architecture for Sensor NetworkS

In a battery-powered sensor network, energy and communication bandwidth are both limited. Moreover, processing a sensor measurement locally often requires orders of magnitude less energy than communicating it to a distant node, yielding an interesting communication/computation tradeoff: whenever possible, the network should reduce the need for global communication at the expense of increased local processing and communication. A promising approach for reducing global communication is to perform signal processing to extract key information inside the sensor network in a distributed fashion, thus dramatically reducing global communication requirements without losing fidelity. In this session, we will overview the COMPASS project, an NSF-funded initiative to develop and new sensor network architecture whose communications hierarchy is aligned with the information flow of its computations.
