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.

过去几年，移动的数据消费出现了前所未有的增长。无线数据的增长在很大程度上是由智能手机和平板电脑的快速普及所推动的，这给无线行业带来了巨大的挑战，无线行业一直无法满足通过蜂窝网络对丰富的移动的内容的需求。这导致网络运营商对解决方案的研究，这些解决方案旨在利用这些移动的设备中存在的WiFi无线电来递送内容而不使用蜂窝无线电链路，也称为内容卸载。 行业主导的方法旨在利用接入点形式的WiFi基础设施来卸载此内容，但这些方法存在各种部署问题。研究最近集中在基于邻近的对等内容共享的潜力上，因为邻近使得能够进行低功率、高速数据交换，这又允许移动的设备主动地彼此共享数据。到目前为止，还没有使用真实世界情况的大规模研究确定这种内容共享提供容量增益的潜力。该提案旨在进行扎实的初步试点研究，评估这一领域的几项基本主张，特别是在正确的时间、正确的地点以及合理可行的部署方案中是否存在足够的潜力。拟议的工作将收集和评估两个高度顺从的环境（WiFi在多个尾门提供数百名用户）以及更具挑战性的环境（每日往返于芝加哥的通勤列车）的试点数据。这项工作的更广泛的影响将是要么证明基于邻近的解决方案的潜在可行性，要么提出令人信服的证据，证明这种邻近解决方案不太可能产生显着的好处。进一步更广泛的影响，工作包括数据共享能力的时间特性的冗余跨移动的设备在几个现实世界的情况。
