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.
Claims21
A method for locating a set of target transmitting mechanisms using a mobile sensing infrastructure, the method comprising:
- determining a reference frame of a mobile sensing mechanism by detecting signals from at least two transmitting mechanisms;
- determining locations of other transmitting mechanisms, which are the target transmitting mechanisms, relative to the reference frame using the sensing mechanism;
- and
- producing a result to indicate the locations of the target transmitting mechanisms.
A system for locating a set of target transmitting mechanisms using a mobile sensing infrastructure, the system comprising:
- a mobile sensing mechanism configured to:
- determine a reference frame by detecting signals from at least two transmitting mechanisms;
- and
- determine locations of other transmitting mechanisms, which are the target transmitting mechanisms, relative to the reference frame;
- and
- a result-generation mechanism configured to produce a result to indicate the locations of the target transmitting mechanisms.
A computer readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for locating a set of target transmitting mechanisms using a mobile sensing infrastructure, the method comprising:
- determining a reference frame of a mobile sensing mechanism by detecting signals from at least two transmitting mechanisms;
- determining locations of other transmitting mechanisms, which are the target transmitting mechanisms, relative to the reference frame using the sensing mechanism;
- and
- producing a result to indicate the locations of the target transmitting mechanisms.
