METHOD OF PROCESSING COMMUNICATION IN NODE COMPOSED WIRELESS SENSOR NETWORK FOR LOW POWER

摘要

PURPOSE: A method of processing communication in a node composed wireless sensor network for low power is provided to extend the operation time of a node by efficiently using limited power in each node. CONSTITUTION: A node checks the existence of data to be transmitted(206), and broadcasts a regards packet for priority declaration for a target node(216). If there is a response packet for the regards packet, the node enters a lower power mode(218,214). If the regards packet for priority declaration to the target node is received from another node during the standby, the node transmits the response packet to the corresponding node(220,224,226).
