博弈式移动云服务协作资源管理模型研究

摘要

For mobile cloud computing application services with high real-time requirement,the efficient bandwidth and computing resources management are particularly important.While the number of application examples capably supported by the mobile application services providers is limited because of the limited resources possessed by them respectively,their revenue cannot increase effectively either. In order to make the these providers be available in resources collaboration and effectively increase their revenue,we propose a collaborative resources management model which combines the resource allocation and the cooperative game theory,it consists of the sub-models of resource allocation,income management and collaboration formation.The resources allocation provides guidance to service providers for the number of resources invested into cooperation;the model combines the income management of cooperation game theory and the collaboration formation model and uses them in fairly dividing the revenues of cooperative earnings and forming stable coalition.Experiment indicates that with the use of resources collaboration between services providers,the cooperation coalition can more effectively utilise the existing resources and the income of them increases 5% and higher.%对于实时要求高的移动云计算应用服务，高效的带宽和计算资源管理尤为重要，而移动程序服务提供商们因各自拥有的资源有限，导致能够支持的程序实例的数量受限，其收入也不能有效提高。为了让移动程序服务提供商进行资源协作并有效提高收入，提出一种资源分配与合作博弈理论相结合的协作资源管理模型，由资源分配、收益管理、协作形成子模型构成。资源分配指导服务提供商投入合作的资源数量；结合了合作博弈理论的收益管理和协作形成模型用于公平划分合作所得收入与形成稳定的联盟。实验表明，服务提供商资源协作使用之后，合作联盟能够更加有效地利用现有资源，服务商的收入可提高5％以上。
