基于微数据中心的低能耗移动流媒体分发机制研究

随着移动互联网的发展和移动智能终端的普及，如何低代价地进行大规模移动流媒体分发成为一个亟待解决的重要研究问题。在本项目中，我们提出一种基于微数据中心的低能耗分布式移动流媒体分发机制，提高面向以智能手机为代表的移动终端的流媒体分发效率，优化移动终端的流媒体服务质量，增强流媒体分发平台的可扩展性，更好地支持各种类型流媒体的分发（包括高清视频、三维视频流、用户创建视频等）。通过本项目，我们将提出新型体系结构，建立理论框架，设计关键算法，开发原型系统和开放协议，从而为建立基于微数据中心架构的移动流媒体分发系统奠定基础。

With the prevalence of mobile terminals (such as smart phones, tablet PCs, etc), how to conduct large-scale mobile streaming at low cost becomes a very challenging problem. In this project, we will propose an energy-efficient cloudlet-based mobile streaming framework, which aims at improving the efficiency of mobile media distribution, optimizing the streaming quality, enhancing the scalability of the distribution platform and supporting the distribution of various media types (including HD video, 3D video, user-generated video, etc.). To achieve the above objectives, we will explore a new mobile streaming architecture, conduct theoretical analysis, design key algorithms, and develop the corresponding prototype and protocols. The success of this project can lay the foundation for the next-generation cloudlet-based mobile streaming platform.
