A Multi QoS Disk Scheduling Strategy(MQDS) framework need to be created where it contains three layers. First layer is Cloudlets layer where the Cloudlets will be divided as such time sensitive, cost sensitive and dynamic requirement tasks. These Cloudlets will be sent to second layer, Resource allocation layer where the workload and price will be collected. According to the conditions, the tasks will be scheduled to the resource layer using three different types of algorithms. You can go through the framework picture that's provided in project paper. At the end the proposed algorithms should be energy efficient. Simulation need to be done using CloudSim and CloudSimDisk simulators. A simple framework of MQDS and implementing algorithms is enough, you can go through the framework diagram given in the project paper attached.
