Abstract:
1. A method for correcting time codes generated by a plurality of sensors, comprising: receiving sensor data from at least one sensor of the plurality of sensors, wherein the sensor data received from the at least one sensor includes a time code generated by the at least one sensor, the time code indicating a time at which the at least one sensor sensed a beacon; constructing a proximity-based ad hoc network among the plurality of sensors based on the received sensor data; collectively analyzing time codes generated by a group of spatially proximate sensors in the proximity-based ad hoc network; modifying a time code generated by at least one sensor in the group based on the collective analysis; and delivering one or more location-based services to at least one of the plurality of sensors, wherein a location tracking manager updates the proximity-based ad hoc network using the modified time code generated by the at least one sensor.
