The Survey on Efficient Coalition Formation Game in Cloud Federation for Multimedia Applications

This paper studies distributed formation of femto-clouds in a UMTS LTE network. Femtocell access points (FAPs) are equipped with computational resources. They share their resources with neighboring FAPs and form local clouds with the aim to avoid the remote cloud costs while improving the user quality of experience (QoE) in terms of handling latency. In exchange for sharing their excess resources, FAPs receive monetary incentives proportional to their contribution in performing computational tasks in the femto-cloud. the growing demand for various mul timedia services and applications has imposed great chal lenges in terms of real-time processing, storing, analyzing and sharing of large media data. Federation among media cloud providers can be a promising solution for effectively hosting multimedia applications and provisioning of Quality of Service (QoS)assured services. In this paper, we address the problem of efficient federation formation mechanism among media cloud providers (CPs) that motivates them to cooperate to fulfill the dynamic resource demands of users for running multimedia workloads. We design a novel media cloud federation formation mechanism based on cooperative game theory. By collaborating to trustworthy providers, our proposed method looks for building federations to minimize the penalties due to possible violation of service quality by untrustworthy providers, and thereby, generate more profit. Simulation results demonstrated that the media cloud federation obtained by the proposed mechanism is stable and provide higher profit for the participating CPs.
