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

网络浏览是智能手机提供的最常见和最重要的服务之一。 然而，它目前存在长时间的延迟，并对智能手机的电池寿命造成了巨大的消耗。 这些限制是由移动的web浏览器中的处理流与无线电接口的专用特性之间的复杂交互以及由智能电话的处理限制引起的。 本计画针对这些限制，着重于三个相互交织的议题：（i）设计、实作与评估各种技术，以重新组织网页浏览器的运算顺序，让无线电介面更早进入睡眠;（ii）引入基于实用数据挖掘的方法来预测用户浏览网页的时间并确定智能手机何时应切换到低功率状态，考虑到智能手机的资源限制以及延迟和功率之间的各种权衡;以及（iii）提出了一种新的架构，以将计算从智能手机转移到基于虚拟机的代理，以解决智能手机中的计算限制，考虑到可扩展性问题和带宽约束。 该项目将在降低无线网络中网页浏览的功耗和访问延迟方面取得重大的理论和技术进展。该项目的成功将影响许多人的日常生活，使智能手机使用时间更长，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介绍广泛传播。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.
