A new SSO-based Algorithm for the Bi-Objective Time-constrained task Scheduling Problem in Cloud Computing Services
share
Cloud computing distributes computing tasks across numerous distributed resources for large-scale calculation. The task scheduling problem is a long-standing problem in cloud-computing services with the purpose of determining the quality, availability, reliability, and ability of the cloud computing. This paper is an extension and a correction to our previous conference paper entitled Multi Objective Scheduling in Cloud Computing Using MOSSO published in 2018 IEEE Congress on Evolutionary Computation. More new algorithms, testing, and comparisons have been implemented to solve the bi-objective time-constrained task scheduling problem in a more efficient manner. Furthermore, this paper developed a new SSO-based algorithm called the bi-objective simplified swarm optimization to fix the error in previous SSO-based algorithm to address the task-scheduling problem. From the results obtained from the new experiments conducted, the proposed BSSO outperforms existing famous algorithms, e.g., NSGA-II, MOPSO, and MOSSO in the convergence, diversity, number of obtained temporary nondominated solutions, and the number of obtained real nondominated solutions. The results propound that the proposed BSSO can successfully achieve the aim of this work.
