Abstract
One embodiment of the present invention provides a system that locates a set of target transmitting mechanism using a mobile sensing infrastructure. During operation, the system determines a reference frame of a sensing mechanism by detecting signals from at least two transmitting mechanisms. The system further determines locations of the target transmitting mechanism relative to the reference frame using the sensing mechanism. In addition, the system produces a result to indicate the locations of the target transmitting mechanisms.
