| Research Abstract |
This study proposes a method to construct a hierarchical distributed hash table based on node distance metrics. The hierarchy is determined by a clustering method that classifies nodes on the Internet by some distance metric like RTT (Round Trip Time) or hop counts between nodes. The proposed method reduces communication overhead between nodes on an overlay network making use of communication locality on the Internet.
