Research on trust mechanism-based resource scheduling in grid environment

Trust is an important factor for scheduling in grid environments. It is also a pivotal technology for the efficiency and performance of grid computing. Trust mechanism is introduced for scheduling in grid environments. A trust model and trust mechanism-based resource scheduling model in grid are proposed. Based on the trust model, Min-Min algorithm is enhanced to ensure security during the scheduling, the Trust-based-Min-Min algorithm is proposed. Simulation results indicate that the algorithm can decrease the completion time of tasks, improve the load balance. Therefore it is an efficient scheduling algorithm for scheduling in grid environments.
