Abstract: 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.

Abstract: Disclosed is an asynchronous MAC based sensor node using a Wake-Up RF. The sensor node includes a main transceiver to transmit/receive data, a Wake-Up transceiver to transit a state of the sensor node; and a micro-control unit, which transmits a Wake-Up frame to at least one receiving node through the Wake-Up transceiver such that the receiving node is activated from an inactive state into an active state and transmits data to the activated receiving node through the main transceiver. The asynchronous MAC based sensor node reduces unnecessary power consumption, hop-by-hop delay, and overhead required for timing synchronization, thereby implementing an effective sensor
