ABSTRACT:
A system and method for saving sensor power consumption based on context information on a wireless sensor network are provided. Basic context information is received from inside and outside of a network system including at least one sensor, wherein context information based on the basic context information is determined by inference, a group of expected services corresponding to the context information is determined, a sensor operation mode according to the group of expected services is determined, and control data is transmitted to the sensor according to the sensor operation mode. Accordingly, a sensor operation mode is adaptively determined according to changes of context information so that power consumption of a sensor can be saved.
