SENSOR NODE, RECEPTION NODE, WIRELESS NETWORK SYSTEM INCLUDING SENSOR NODE AND RECEPTION NODE, AND OPERATION METHOD OF SENSOR NODE AND RECEPTION NODE
Disclosed is a sensor node in a wireless network system including at least one reception node and a plurality of sensor nodes. One embodiment comprises: a detection unit for detecting an event which occurs within the wireless network system; a processor for checking whether the sensor node can participate in a first transmission group formed on the basis of a first channel gain of a channel configured between the sensor node and the reception node and a second channel gain of a channel configured between each of the plurality of the sensor nodes and the reception node, and configuring a transmission power of the sensor node to satisfy a predetermined standard according to the checking; and a transmission unit for transmitting data generated according to the detected event to the reception node.
