Improving grid nodes coalitions by using reputation

Abstract

In this work we deal with the issue of improving the QoS provided by each node of a Grid Federation, by modelling it as a problem of “Grid formation”. In the proposed model each Grid node belonging to a computationalGrid, is free to join with or leave a grid with the goal of improving its satisfaction. Contextually, each grid is free to search other nodes to join with it or to remove those nodes resulted ineffective. Software agents manage the node profiles and in our model a Grid agent has the role of handling the profile of the Grid.We introduce a distributed algorithm, called GF, to handle the node activity of joining to the grid, modelled as a matching problem. Some experiments shown the effectiveness of our approach.
