Paper Abstract

It is necessary to build spatial index in order to managing complex spatial data in peer-to-peer (P2P) environments. This paper analysis and summarizes the related studies, designs a new spatial index model named P2PQR-tree which uses the distributed Quad-tree and the local R*-tree. P2PQR-tree applies Quad-tree techniques into P2P environments and uses replication strategy to improve the system's load balance. This paper includes gives the models definitions, the model's architecture design, the model's performance analysis results. P2PQR-tree has some advantages to the old methods, for example, its data management is more reasonable, it can support metadata management better, implement rights control easier, reduce changes of distributed index, and adapt to dynamic character of P2P network better.
