Abstract: A wireless sensor network communication apparatus and method selectively using infrared and radio frequency communication. The wireless sensor network communication apparatus includes a first communicating unit, a second communication unit, and a wireless node processor. The first communicating unit wakens a neighboring node in a sleep mode and transmits/receives the woken node and sensor data. The second communicating unit transmits/receives the woken neighboring node and the sensor data. The wireless node processor is wakened from the sleep mode, wakens the neighboring node in the sleep mode, and transmits the sensor data with a minimum low power through one of the first and second communicating unit. Accordingly, the apparatus can perform the wireless sensor network communication with lower power compared to the case that communication is performed only by the radio frequency communication function.

Abstract: The present invention relates to a remote control system, a remote server, a remote control agent, and a remote control method. According to the present invention, when controlling the remote apparatus to perform a target service, remote apparatus information and service information are searched and a service plan is generated based on the searched remote apparatus information and service information for execution of the target service. In addition, a remote apparatus control process generated by the service plan and the process is performed. Therefore, users can easily control the remote apparatus and can be provided desired services.
