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

Abstract: PURPOSE: A routing method for an end-device in a wireless sensor network is provided to transmit the data in case an end-device transmits data in a wireless sensor network. CONSTITUTION: A neighbor information table for storing an address of a neighbor device is maintained. In case a destination address of a transmission target is an end-device, it is searched whether there is a parent address or a forebear address of a destination address on the neighbor information table(801,803,806). If the address is searched on the neighbor information table, data of the transmission target is transmitted to the searched address(804).
