提出一种基于本体的信任模型可信动态级调度算法,提高了信任度计算的粒度,并对执行复合任务序列提供了支持.仿真实验表明,作者提出的可信动态级调度算法能在复合任务调度中取得较高的任务执行率.
Establishing dynamic trust relation is the beginning of interaction and cooperation among entities under large scale distributed environment.The computing of t Trustworthiness in current trust dynamic level scheduling algorithm is a little rough,and they only research the scheduling algorithms which apply in executing sequence tasks.A new trust dynamic level scheduling algorithm based ontology trust model is presented.It improves the trust computation for different aspects and supports executing composite tasks.Simulation experiments prove that the algorithm can assure the execution of composite tasks in a highly successful level in task scheduling.
