<p>Systems and methods for using distributed processing in conjunction with blind source separation techniques for signal processing and acquisition in sensor network environments are provided. In the distributed blind source separation framework, sensors perform processing of sensor signals rather than transmit such signals over long distances, and/or outside of the sensor network, for processing at a central location. Sensors attempt to own a source signal, and a source signal can only be owned by one active sensor. Sensors owning a source signal broadcast the signal directly or indirectly so that it is perceived by users. Sensors receive information from other sensors in their sensor neighborhood, including observed signals of the other sensors and estimated source signals of sources owned by the other sensors. Owning sensors extract the respective source signals associated with the sources they own and redundant sensors can check for any non-owned source signals present.</p> |
