Providing services such as voice, web, cloud computing, social networking, video on demand, live streaming and augmented reality requires the ability to globally handle massive amounts of data, which must be efficiently processed, stored, and delivered to end users. The medium of delivery is shifting from wireline to wireless; it is predicted that mobile traffic will account for nearly two-thirds of the total data traffic by 2018 and nearly three fourths of the mobile data traffic will be video by 2019. This puts a tremendous pressure on the limited wireless bandwidth and necessitates revolutionary approaches that exploit alternative resources available in the network. Motivated by the decreasing cost and abundance of storage capacity, this project considers joint design of storage and transmission schemes for the efficient delivery of video-based services over next generation heterogeneous wireless networks, by specifically taking into account the unique nature of video content and the wireless channel.In order to accomplish this ambitious task, the work is organized into the three research thrusts that develop next generation of wireless caching networks for video delivery:-Thrust 1: Fundamental limits and practical schemes for cache-aided video delivery:This thrust takes into account properties of video applications and their associated requirements for efficient and robust caching and delivery techniques particularly suited for such demands. -Thrust 2: Video delivery over future cache-aided heterogeneous wireless networks:This thrust builds upon the foundations developed in Thrust 1 and expands the cache-aided video delivery schemes to consider and take advantage of heterogeneous wireless channel conditions and network topologies. - Thrust 3: Technology validation and experimentation: This thrust includes proof-of-concept prototyping efforts to validate the designs developed in this project.The broader impacts resulting from the activity in this project will include significant enhancement of video delivery mechanisms over wireless channels beyond the current state of the art. This of key importance since the total global mobile traffic was about 885 petabytes per month at the end of 2012, and is expected to keep increasing. As the storage capacity becomes cheaper, the techniques developed in this project will be able to alleviate the spectrum crunch by trading off memory for bandwidth. Industry outreach and dissemination will be done through Bell Labs Nokia and other industrial partners at NYU. The PIs are committed to and have an excellent track record in increasing participation of as well as mentoring women and underrepresented minorities in the STEM fields. This grant will help to support these efforts.

提供语音、网络、云计算、社交网络、视频点播、直播和增强现实等服务需要能够在全球范围内处理大量数据，这些数据必须得到有效处理、存储并交付给最终用户。传输媒介正在从有线向无线转移;据预测，到2018年，移动的流量将占总数据流量的近三分之二，到2019年，移动的数据流量的近四分之三将是视频。这给有限的无线带宽带来了巨大的压力，需要采用革命性的方法来利用网络中可用的替代资源。 受成本下降和存储容量充足的推动，本项目考虑联合设计存储和传输方案，以便在下一代异构无线网络上有效地提供基于视频的服务，特别是考虑到视频内容和无线信道的独特性质。为了完成这一雄心勃勃的任务，这项工作被组织成三个研究重点，开发下一代无线高速缓存网络用于视频传输：-重点1：高速缓存辅助视频传输的基本限制和实用方案：这一推力考虑到视频应用程序的属性及其相关的要求，高效和强大的缓存和交付技术，特别适合于这种需求。- 推力2：未来高速缓存辅助异构无线网络上的视频传输：这一突破建立在突破1中开发的基础之上，并扩展了高速缓存辅助视频传输方案，以考虑和利用异构无线信道条件和网络拓扑。- 推力3：技术验证和实验：这一举措包括证明-概念原型工作，以验证本项目中开发的设计。本项目中的活动产生的更广泛影响将包括无线信道上视频传输机制的显著增强，超越当前的技术水平。这一点至关重要，因为截至2009年底，全球移动的总流量约为每月885 PB。2012年，预计将继续增长。随着存储容量变得更便宜，该项目中开发的技术将能够通过用内存换取带宽来缓解频谱紧缩。行业推广和传播将通过贝尔实验室、诺基亚和纽约大学的其他行业合作伙伴完成。 PI致力于增加妇女和代表性不足的少数民族在STEM领域的参与和指导，并在这方面有着良好的记录。这笔赠款将有助于支持这些努力。
