为了减少任务调度过程中使用传统安全措施带来的网格开销,提出把信任关系作为安全衡量标准融入网格环境下的任务调度策略中,并综合考虑任务、资源双方的安全需求和系统的负载平衡,设计了调度算法Trust-based Min-min,仿真试验证明了该算法是合理的和有效的. In order to reduce the grid overhead caused by using traditional security measures in the task scheduling process, this paper proposes to integrate the trust relationship as a security measure into the task scheduling strategy under the grid environment. Considering the security requirements of both tasks and resources and the system load In this paper, we design Trust-based Min-min scheduling algorithm. Simulation results show that the proposed algorithm is reasonable and effective.
