中文摘要: 随着智能手机和移动互联网的发展,手机充当了互联网的终端,并且手机摄像头使得手机变成了视频内容的获取来源和存储器。2012年的移动数据流量是2000年整个全球互联网规模的近12倍,其中60%的流量来自用户观看视频。面对如此巨大的移动互联网流量,现有的传输网络带宽根本不够。移动网流量卸载对电信运营商的重要性不言而喻。由于60%的流量是用户在WiFi覆盖的范围内使用移动互联网业务的,研究基于WiFi的移动互联网流量卸载具有十分重要的理论和实际利益。本课题研究移动终端(手机)之间进行内容分发和共享中的若干关键科学问题。本课题提出一种移动互联网环境下由移动终端和WiFi组成的新型网络结构:超WiFi网络。移动终端(手机)之间基于本课题提出的网络结构和模型完成内容分发和传输,用户可获得超过传统方式的高速的下载速率,又减轻蜂窝移动通信网络骨干网上的流量,实现移动互联网流量卸载。

英文摘要: With the development of smart phones and mobile Internet, mobile phones act as Internet terminals and cell phone camera makes the phone be a resource of video content. The mobile data traffic in 2012 is nearly 12 times the size of the entire global Internet in 2000. About 60 % of the traffic comes from users to watch video. Faced with such a huge mobile Internet traffic, the existing transmission network bandwidth is not enough. The importance of mobile network traffic offloading is self-evident for telecom operators. 60% of the traffic is the use of mobile Internet services in the range of WiFi coverage, so mobile Internet offloading based on WiFi is theoretical important and brings practical interest. The research focuses on a number of key scientific issues in content distribution between mobile terminals ( mobile phones ). This project proposes new network architecture for mobile Internet environment consisting of the mobile terminals and WiFi: Super WiFi network. To complete content distribution and transmission between the mobile terminal (mobile phone) based on the Super WiFi network structure and the model the topics proposed, users get more than the traditional way of high-speed download rate, but also reduce cellular mobile communications network backbone traffic.
