云计算中基于服务能力与信任约束的任务调度算法
A task scheduling algorithm based on service ability and trust constraint in cloud computing
摘要
Abstract
In view of selecting trusted service and multiple constraint objects in cloud computing,a task scheduling algorithm based on service ability and trust constraint is proposed.Firstly the service ability and creditability of resources are assessed. And then during the process of task scheduling,the candidate resources are selected if their service ability meets the require-ments of users.Furthermore a comprehensive benefit function is designed by the weight of the trust benefit and cost,re-source with the biggest comprehensive benefit is selected from the candidate resources.Finally the task is assigned to a re-source according to load balancing strategy.Simulation results show that the algorithm can satisfy service ability and the trust requirements of users.And the performance and load balance of the system is good.关键词
