The past few years have seen unprecedented growth in mobile data consumption. Powered in large part by the rapid adoption of smart phones and tablets, the growth in wireless data creates phenomenal challenges for the wireless industry, which has been unable to meet the demand for rich mobile content through cellular networks. This has led to the investigation of solutions by network operators that aim to utilize WiFi radios present in these mobile devices to deliver content without using the cellular radio links, also known as content-offloading. Industry-led approaches aim to utilize WiFi infrastructure in the form of access points to offload this content, but these have various deployment issues. Research has lately focused on the potential of proximity-based peer content sharing, since proximity enables low-power, high speed data exchanges which in turn allows mobile devices to proactively share data with one another. No large-scale study using real-world situations has established the potential for such content-sharing to provide capacity gains, until now. This proposal aims to conduct solid, preliminary pilot studies evaluating several of the foundational claims in this area, specifically as to whether sufficient potential exists in the right time, right place, and with reasonably viable deployment scenarios. The proposed work will gather and evaluate pilot data in both highly amenable environments (WiFi across multiple tailgate offerings of hundreds of users) as well as more challenging environments (daily commuter trains to / from Chicago).The broader impact of the work will be to either demonstrate the potential viability for proximity-based solutions or to present compelling evidence that such proximity solutions are unlikely to yield significant benefits. Further broader impacts for the work include data sharing capabilities with respect to temporal characterizations of redundancy across mobile devices in several real-world scenarios.

在过去的几年中，移动数据消费始终增长了前所未有的增长。无线数据的增长在很大程度上是由于智能手机和平板电脑的迅速采用，对无线行业带来了惊人的挑战，无线行业无法通过蜂窝网络满足对丰富移动内容的需求。这导致了网络运营商对解决方案的调查，该网络运营商旨在利用这些移动设备中存在的WiFi无线电，以在不使用蜂窝无线电链接（也称为Content Proading）的情况下提供内容。 以行业为主导的方法旨在利用访问点的形式利用WiFi基础架构来卸载此内容，但这些内容都有各种部署问题。最近，研究集中在基于接近性的同伴内容共享的潜力上，因为接近性可以实现低功率，高速数据交换，从而使移动设备可以主动共享数据。到目前为止，没有使用现实情况下的大规模研究确定了这种内容共享的潜力。该提案旨在进行扎实的初步试点研究，以评估该领域中的几个基础主张，特别是关于是否存在适当的时间，正确的位置和合理可行的部署方案。拟议的工作将在高度合适的环境（跨多个用户的多个后挡板产品上的WiFi）以及更具挑战性的环境（日常通勤者乘坐往返芝加哥的通勤火车）中收集和评估试验数据。该工作的更广泛的影响是为了证明基于Proximity的解决方案的潜在活力，以表现出强大的证据，以至于既有质疑的差异，都可以表现出较大的能力。对这项工作的进一步更广泛的影响包括在几种现实世界中跨移动设备的冗余的时间特征方面的数据共享功能。
