HEAD NODE SELECTION METHOD FOR CLUSTERING IN WIRELESS SENSOR NETWORK AND WIRELESS SENSOR NETWORK

摘要

The present invention relates to a wireless sensor network, and more particularly, to a head node selection method for clustering in a wireless sensor network and a wireless sensor network. The wireless sensor network for determining a head node that includes: a first node; and a second node wirelessly being in communication with the first node, wherein the first node broadcasts a final head node message which is a message indicating that the first node itself is a final head node to the second node if the residual energy of the first node is larger than the residual energy of the neighboring nodes. It is therefore possible to minimize clustering process time.
