METHOD FOR UPDATING FIRMWARE OF SENSOR NODES ON A WIRELESS SENSOR NETWORK AND FIRMWARE UPDATER USING FOR THE SAME METHOD

摘要

PURPOSE: A firmware update method of a wireless network node and a firmware update apparatus used for the same are provided to update the firmware of new node by communication with the connected node. CONSTITUTION: A new node searches a neighbor node within a specific distance in a receiving state. The new node sets up a parent node among the searched neighbor node. In case a plurality of nodes includes a joining receiving state for joining new node in wireless network, a communication unit(110) sets up first communication link in a new joining state. A firmware of the parent node is transmitted to the new node through the first communication link. The new node updates the existing firmware in case the transmitted firmware is received.
