Peer-to-Peer Management of Large-Scale Memory Sources

Hosting University

Dublin City University

Overview

The Interoperable System's Group (ISG) conducts research into Peer-to-Peer (P2P) database systems. This provides a nice model of human memory: many sources of memory, arriving in different forms. Sources of memory may include a table of names, a video image of a recent event or a photograph. Each of these items is stored away in separate locations, representing different parts of the brain.

The P2P Simulation project involves the construction of a Peer-to-Peer simulation system that can be used 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 database. This is a single document (127MB) used to store the publications for all database and language processing researchers. With almost 3.5 million nodes, this is well-suited to the construction of a P2P simulation or large-scale memory sources. The proposed system provides the basis for running experiments required to assess the ISG's P2P Query Processor.

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 including different forms of media and sensor data (video and sensory memories). This allows us to quickly integrate other domains (or disciplines) into a P2P setup to gain advantage of our Query Processing capabilities.

Relevance to Host Laboratory

The ISG has (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. The architecture has been specified for some time and more recently, a method for dynamic processing of queries has been specified. What is now required is a simulation system to test the P2P query method and the power of our indexing architecture.
