Description
Summary:A major problem in mobile computing is the optimal replication and location of data files in the Grid sites, in order to improve and maintain over time a high overall throughput of Grid jobs that access files. Therefore, a Grid optimization service should be able to dynamically modify the geographic distribution of data files, triggering file replication and location, according to the variation over time of the sites where data is highly requested. In this document we propose a new decentralized replica location method in mobile Grids. In this method replica location index information are spread evenly on index nodes. Meanwhile it employs replica location nodes to support local query for local replicas. We can locate the index nodes quickly from the logical file names and achieve scalability and good load balance. It turns out that, over the performed tests, it spend less time to execute location in this method.
