  • Systems and methods for telescopic data compression in sensor networks
    Patent number: 7952963
    Abstract: Systems and methods for telescopic data compression in sensor networks are disclosed herein. An exemplary method of the disclosed subject matter for telescopically compressing data received from a plurality of sensors in a network adapted to detect a field includes broadcasting a first set of sampling positions to sensors, forming a first set of clusters of sensors based on the sampling positions, receiving data from the sensors contained within the clusters, performing local interpolation of the received data, reconstructing a representation of the field using the interpolated data, and determining areas of interest based on the reconstructed representation of the field.
    Type: Grant
    Filed: November 10, 2009
    Date of Patent: May 31, 2011
    Assignee: The Trustees of Columbia University in the City of New York
    Inventors: Patrick Y. H. Cheung, Nicholas F. Maxemchuck
