An approach for resource selection and allocation in grid based on trust management system

In grid computing, resources can be given and retrieved by grid nodes freely. The wide range of selection and the high degree of strangeness bring lots of problems in secure selection of grid. Efficient resource allocation and utilization can hardly be achieved without the assurance of a high degree of confidence relation. In this paper, we propose a solution based on trust mechanism. The trust management system maintains a trust value for each participant node in its grid domain based on the performance and behavior of each node. The resource allocation utilization procedure makes decision based on the trust value provided by the trust management system. The simulation result shows that our approach can achieve lower failure percentage. Besides, the approach can get rid of the bad node with malicious behavior in history.
