摘要：Resource scheduling is a key process for IaaS clouds. IaaS clouds commonly take Virtual Machine (VM) as scheduling unit, be allocated to heterogeneous physical resources and cloudlets as processing units allocated to virtual machines. The scheduling of VM and Cloudlet with various timing constraints requires dynamic, predictable and exible control mechanisms. The basic goal is to decrease or optimize job execution or turnaround timeanddecrease or minimize delay time at server side keeping in consideration the threshold time given by client side. To simplify this process, in this paper we propose a policy of two level task (cloudlet) scheduler using time shared at first level and rank (priority) at second level. We have used cloudsim for simulating the proposed scheduling policy.
