A. Autonomous Clustering
Clustering is a technique to manage networks hierarchically. It divides networks into disjoint sub-networks (called clusters). Autonomous Clustering has a cluster head and cluster members in each of clusters. A cluster head collects the cluster member information to configure the tree structure rooted at itself. In addition, a cluster head adjusts the size of the cluster by dividing or combining clusters with upper or lower bounds on the number of the cluster members.
