ABSTRACT:
Methods and apparatuses for locating a sensor node are disclosed. A representative apparatus, among others, includes a processing unit that receives sensor node data and object trajectory information data for an object. The sensor node data is related to the object's trajectory, and a data point in the object trajectory information data comprises a time stamp and the coordinates of a position. The position corresponds the location of the object at the given time. The processing unit is adapted to correlate at least a portion of the sensor node data with at least a portion of the object trajectory information data to determine an absolute position of the sensor node.
