移动云计算有望满足对资源受限移动设备的更丰富应用和服务的迫切需求，它正在成为一种新的计算范式，并且最近引起了极大的关注。但是，由于商业炒作以及将云计算和移动应用程序结合的多种方式，没有明确的定义，也没有明确的移动云计算范围。本文首次尝试从预期用法的角度提出移动云计算的调查。具体来说，我们将三种常见的移动云体系结构介绍为两个基本类别：计算卸载和功能扩展。考虑到移动设备的能源瓶颈和用户背景，我们讨论了引入云计算以协助移动设备的研究挑战和机会，包括节能交互，虚拟机器迁移开销，隐私和安全性。此外，我们演示了由移动云计算启用的三个现实世界应用程序，以刺激该新兴领域的进一步讨论和开发。
Mobile cloud computing, with its promise to meet the urgent need for richer applications and services of resource-constrained mobile devices, is emerging as a new computing paradigm and has recently attracted significant attention. However, there is no clear definition and no well defined scope for mobile cloud computing due to commercial hype, and diverse ways of combining cloud computing and mobile applications. This article makes the first attempt to present a survey of mobile cloud computing from the perspective of its intended usages. Specifically, we introduce three common mobile cloud architectures and classify comprehensive existing work into two fundamental categories: computation offloading and capability extending. Considering the energy bottleneck and user context of mobile devices, we discuss the research challenges and opportunities of introducing cloud computing to assist mobile devices, including energy-efficient interactions, virtual machine migration overhead, privacy, and security. Moreover, we demonstrate three real-world applications enabled by mobile cloud computing, in order to stimulate further discussion and development of this emerging field.
