HEAD NODE SELECTION METHOD FOR A CLUSTERING IN A WIRELESS SENSOR NETWORK AND A WIRELESS SENSOR NETWORK FOR THE SAME

摘要

PURPOSE: A head node selection method for a clustering in a wireless sensor network is provided to minimize the clustering process time in a distributed wireless sensor network.;CONSTITUTION: A node determines whether the final head node message is received from a candidate head node within a predetermined time(S460). If the final head node message is received within the predetermined time from the candidate head node, the node determines the candidate head node as the final head node(S470). If the final head node message is not received within the predetermined time from the candidate head node, the node selects the candidate head node as a relay node(S480).;COPYRIGHT KIPO 2011
