Hierarchical task scheduling model based on trust mechanism in grid computing
Jianjun Li · Computer Engineering and Applications Journal · 2012
This paper proposes a hierarchical task scheduling model that divides the task scheduling into two parts,the choice of the resource site and local scheduling within the resource site, and in the first part, it introduces trust mechanism. Then it presents the appropriate algorithm, which not only takes the trust relationship between girding entities, the requirements of QoS and price factors into account, but also adjusts their weights dynamically in the exchange. The final simulization and anlysis show the model can effectively increase the security and efficiency of the Grid system.
