PSON: A Scalable Peer-to-Peer File Sharing System Supporting Complex Queries
Jyoti Ahuja, Jun‐Hong Cui, Li Lao, Shigang Chen · 2005
In this work, we design a P2P file sharing system called PSON to address the important issues of scalability, routing efficiency and complex query support. We propose a semantic overlay network of logical nodes, in which queries are routed on the basis of semantics. A logical node is formed by a cluster of peers that are close to each other in the physical network. Each cluster selects a powerful peer as super peer to support routing in the overlay network. All the super peers are organized in the form of a balanced tree. By exploiting the concepts of hierarchy and semantics, PSON can support complex queries in a scalable and efficient way. Our initial results have shown the promising performance of PSON.
