Emerging 5G systems will feature a closer collaboration between mobile network operators and cloud service providers to meet the communication and computational requirements of modern mobile applications and services in a mobile cloud computing (MCC) environment. In this article, we show how the marriage between heterogeneous wireless networks (HetNets) and multiple clouds (a collection of which is referred to here as Intercloud) stands out as an effective response for the mobile data deluge. First, we review the building blocks of a HetNet and an Intercloud as well as the resource management entities in both domains. Second, we outline how they might be orchestrated to better support the task offloading process. Third, we identify the key design criteria and challenges related to interoperation between an Intercloud and a HetNet. We then formulate a revenue sharing approach for a coalition between a mobile network operator and cloud service providers. The approach achieves the maximum revenue for the coalition by optimally associating the users to the clouds through the base stations. Next, the concept of Shapley value is applied to individualize the contribution of each player based on the maximum revenue for the optimal user association. Numerical results illustrate the benefits of the coalition for all players.

5G 系统中移动云计算的 Intercloud 和 HetNet：设计问题、挑战和优化


新兴的 5G 系统将以移动网络运营商和云服务提供商之间更紧密的合作为特色，以满足移动云计算 (MCC) 环境中现代移动应用程序和服务的通信和计算要求。在本文中，我们将展示异构无线网络 (HetNet) 与多个云（此处称为 Intercloud）之间的结合如何成为应对移动数据洪流的有效应对措施。首先，我们回顾 HetNet 和 Intercloud 的构建块以及两个域中的资源管理实体。其次，我们概述了如何编排它们以更好地支持任务卸载过程。第三，我们确定了与 Intercloud 和 HetNet 之间的互操作相关的关键设计标准和挑战。然后，我们为移动网络运营商和云服务提供商之间的联盟制定收入共享方法。该方法通过基站将用户与云进行最佳关联，从而为联盟实现最大收入。接下来，应用沙普利值的概念，根据最佳用户关联的最大收益来个性化每个玩家的贡献。数字结果说明了联盟对所有参与者的好处。
