Zusammenfassung:	PURPOSE: A sensor node based on asynchronous MAC protocol and a data transceiving method performed in the sensor node are provided to solve problems such as data transmitting delay reduction, overhead reduction due to time synchronization and battery consumption amount reduction. CONSTITUTION: A main transceiver(412) transceives data. A wake-up RF module(413) converts state of a node. An MCU(Micro Control Units)(411) transmits a wake-up frame to at least one receiving node through the wake-up RF module. The MCU receives the wake-up frame. The MCU transmits data to an activated receiving node through the main transceiver.
