Cooperative Game Theory-Based Request Distribution Model in Federated Cloud Environment

Abstract

Cloud computing has emerged as the most important paradigm of distributed computing in the last decade. Increasing demand of the cloud users and inadequacy of resources along with the cloud providers has encouraged the federation of multiple cloud providers. In federation, multiple rational providers coordinate for the execution of the user’s tasks. In federated cloud, the distribution of the user’s request for resources and revenue among the providers has evolved as the most challenging task. Existing works aim at the profit maximization of the providers while discounting the importance of fair distribution. This paper presents cooperative game theoretic model for the fair distribution of revenue and resources among the providers, and analyzes the variation of power index with the change in the user’s request. For analysis of the proposed model, comparative evaluation is performed with the existing distribution model. An experimental result demonstrates that the proposed model distributes the resource request and revenue more fairly that the existing state of art.
