Performance Evaluation of Scheduling Algorithms in Cloudlets

The possibility of providing mobile devices with fast and affordable Cloud computing (CC) services is a major motivation for Cloudlet technology. However, for this happen, a suitable scheduling algorithm that minimizes the consumer's (i.e. Mobile devices) waiting time under various Cloudlet scenarios needs to be determined. Hence, determining the suitability of a scheduling algorithm with respect to consumer's waiting time is the main objective of this study. To this end, we first present a brief review of existing scheduling algorithms as a road map towards evaluating the performance of each algorithm. Next, we present the performance evaluation of three popular scheduling algorithms under various Cloudlet scenarios. Specifically, an EdgeCloudSim simulator is used to evaluate the performance of MM1, Priority (PR) and Round Robin (RR) with respect to consumer's waiting time. Results gotten from the simulation show a noticeable difference in the performance of scheduling algorithms for different mobile applications as the number of mobile devices fluctuates.
