NeTS: Small: Efficient Energy-Aware Web Browsing in Wireless Networks

网页浏览是智能手机提供的最常见、最重要的服务之一。然而，它目前遭受了长时间的延迟，并造成了智能手机电池寿命的巨大消耗。这些限制是由移动web浏览器中的处理流与无线无线电接口的专门特性之间的复杂交互以及智能手机的处理限制造成的。本项目通过关注三个相互交织的问题来解决这些限制：(i)设计、实现和评估各种技术，以重组web浏览器的计算序列，使无线无线电接口更早地进入睡眠状态；（ii）引入了实用的基于数据挖掘的方法来预测用户浏览网页的时间，并考虑智能手机的资源限制以及延迟和功耗之间的各种权衡，确定智能手机何时应该切换到低功耗状态；（iii）提出了一种新的架构，将计算从智能手机转移到基于虚拟机的代理，以解决智能手机的计算限制，考虑到可扩展性问题和带宽限制。本项目将在降低无线网络中浏览网页的功耗和访问延迟方面取得重大的理论和技术进步。这个项目的成功会影响很多人的日常生活，让智能手机的使用寿命更长，网页浏览速度更快。该项目的成果将通过高质量的出版物和简报广泛传播。拟议的研究也将与宾夕法尼亚州立大学的教育课程相结合。

Web browsing is one of the most common and important services provided by smartphones. However, it currently suffers from long delays and creates a huge drain on the battery lifetime of smartphones. These limitations are caused by complex interactions between the processing flow in mobile web browsers and specialized characteristics of the wireless radio interface, and by the processing limitations of the smartphones. This project addresses these limitations by focusing on three intertwined issues: (i) various techniques to reorganize the computation sequence of the web browser to let the wireless radio interface enter sleep earlier, are designed, implemented and evaluated; (ii) practical data mining based methods are introduced to predict the user viewing time of webpages and determine when the smartphone should switch to low power state, considering the resource limitations of the smartphone and various tradeoffs between delay and power; and (iii) a new architecture is proposed to shift the computing from smartphones to the virtual-machine based proxy to address the computation limitations in smartphones considering scalability issues and bandwidth constraints. This project will make significant theoretical and technical advances on reducing the power consumption and access delay of web browsing in wireless networks. The success of this project will affect many people's daily life, making smartphones last longer and web browsing faster. The results of the project will be disseminated widely through high quality publications and presentations. The proposed research will also be integrated with the education curricula at the Pennsylvania State University.
