The Interoperable System's Group (ISG) conducts research into Peer-to-Peer (P2P) database systems. The XPeer Simulation project involves the construction of a Peer-to-Peer system necessary to test the ISG's Indexing Method for Tree-Based Systems. The researcher would make use of existing P2P simulation software to construct a system based on the large DBLP XML database7. This is a single document (127MB) used to store the publications for all database and language processing researchers. With almost 3.5 million elements, this is ideally based to provide a worthwhile P2P simulation.

The proposed system is necessary to run the experiments required to assess the ISG's PreLevel Index. The proposed researcher would work within the ISG team and have a clearly defined set of specifications for a single 12-week placement. The output of this proposal is not solely the P2P simulation, but the development of a template for the construction of similar systems. This allows us to quickly integrate other domains (or disciplines) into a P2P setup to gain advantage of our Query Processing capabilities.

Relevance of Project to the Host Laboratories:

The ISG have (together with the University of Montpellier) devised a novel P2P architecture that provides the flexibility and robustness of P2P systems with the data management features of database systems. At this point, the architecture is fully specified with the longer term goal of providing services such as metadata and querying. What is now required is a simulation system to test the conceptual architecture, our query method, and the useful of our metadata service (and semantic repository).
