Abstract: PURPOSE: A clustering method of wireless sensor network is provided to maximize a life time of network sensor nodes by minimizing frequent change of a cluster member and a cluster header. CONSTITUTION: Whole wireless frequency sensor nodes accomplish a network with a base station. One or more cluster header is elected from whole wireless sensor nodes. A hello message is broadcasted from the base station to the whole wireless sensor nodes. The wireless sensor nodes and cluster headers responding to a broadcasting of the base station are counted. A cluster member calculates a critical value of the cluster member and informs to each cluster header. Each cluster header transmits an address message that informs the cluster header to the whole wireless frequency sensor nodes.
