PURPOSE: A wireless sensor node control system and a method for improving energy efficiency are provided to simplify the power supply frequency and procedure to a wireless sensor node. CONSTITUTION: A control server(900) transfers set filtering conditions to a context awareness shim(130). If first sensing data can be transferred to the control server according to the filtering operation under the filtering conditions, the context awareness shim transfers the first sensing data to the control server. The transmission of the first sensing data to the control server is unnecessary, the context awareness does not transfer the first sensing data to the control server. |
