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. |
