Paper Abstract

The structured overlay networks based on DHT provide a decentralized, self-organizing substrate for building the large distributed systems such as file sharing and data storage. However, in most of these systems, many problems still remain to be solved regarding system scalability, network proximity and so on. In this paper, we present a novel routing protocol called PBHC. By combining hierarchical DHT algorithm with a data proximity mechanism PBHC minimizes the intracluster access traffic and boosts the local access ratio in heterogeneous networks environment. The simulation results show PBHC can significantly improve the routing performance and scalability of the P2P storage system.
