CloudSim is useful tool for a simulation of cloud environment. CloudSim can view the availability, a power consumption, and a network traffic of services on cloud environment. However, CloudSim cannot support Quality of Service (QoS). Thus, this paper proposes a cloud-simulating system with QoS using CloudSim. Providing CloudSim with a priority queue is basic solution for offering QoS. Additionally, this paper introduces implementation of priority queue in CloudSim. Proposed system is able to control cloudlets with priority and process them differentially. This advanced CloudSim shows faster complete time than default system in time-sharing policy.
