On Data-intensive Task Scheduling Algorithm in the Grid Environment Based on Trust Model

For the scheduling problems in data-intensive application,a new scheduling algorithm is proposed,which considers both the bandwidth and the trust level of the source sites when choosing the grid nodes.As for the unbalancing problems among many sites when transferring files,an algorithm based on the idea of sufferage is addressed to balance the download loading.The simulation experiment indicates that this algorithm is better than the traditional Min-Min algorithm.
