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 each perform some processing of sensor signals rather than transmitting such signals over long distances, and/or outside of the sensor network, to be processed at a central location. Sensors attempt to own a source signal, which can only be owned by one active sensor. Sensors owning a source signal broadcast the signal directly or indirectly so it is perceived by users. Sensors receive information from other sensors in their sensor neighborhood, including observed signals of the other sensors and the estimated source signals of sources owned by the other sensors. This allows owning sensors to extract the respective source signals of the sources they own and all redundant sensors to check for any non-owned source signals present.
