Abstract:
In cloud computing environment, request management and optimal task assignment to cloud resources are challenging when it faces with increasing the number of users and their requests to use resources. Moreover, maintaining load balancing in this environment leads to shorter response times, boosting of system speed, its security and reliability. Therefore, an effective algorithm is desirable to optimally assign tasks and maintain load balancing. This paper aims to present a method of scheduling and assigning tasks to resources. It is combination of a multi-objective firefly algorithm and fuzzy logic. The purpose of the proposed method is to optimize turnaround time and communication costs in the cloud computing environment. In this study, the multi-objective firefly algorithm is utilized in order to optimize these two parameters simultaneously. Turnaround time is in second and communication cost is in terms of distance traveled (meters). Hence, the current study applied fuzzy logic in order to calculate the degree of fit. The results indicated that 49% and 43% improvement in the turnaround time of the proposed algorithm compared with the genetic algorithm and the simple firefly algorithm. Also, communication costs have also decreased by 21% and 39%, respectively, in comparison with the genetic algorithm and the simple firefly algorithm.
