Method of controlling collection period of sensor data using analysis of dependency between sensor data, and network application server for controlling collection period of sensor data

摘要

Described embodiments relate to a machine to machine (M2M) server for controlling a data collection interval of a M2M device. The M2M server may be configured to determine data dependency between a first M2M device and a second M2M device based on sensing data collected from the first M2M device and the second M2M device and to control a data collection interval of at least one of the first M2M device and the second M2M device based on sensing data variation of one of the first M2M device and the second M2M device.
