Task Scheduling Research Based on Dynamic Backup in Cloud Environment

Abstract:

In order to improve resource utilization in cloud environment and reduce the total task execution time, a new scheduling strategytask scheduling strategy based on dynamic backup was proposed. The cloud system scheduling model was built, according to different security requirements for tasks to users and different trust level for nodes. This model can schedule the number of tasks backup reasonably, according to the change of system trust index. The simulation result shows that, this strategy can improve the overall system efficiency effectively.
