This project develops a transformative mechanism for cooperative object caching in Social Wireless Networks (or SWNETs). The key idea is to reduce wireless bandwidth strain in carriers' 3G/4G networks by intelligently storing user objects within SWNETs formed across mobile devices through short range WiFi style wireless links. The applicable user objects would include phone Apps, mp3 music, video clips, news items, book chapters, and research papers. The key research objectives of the project is to develop a generalized caching framework for managing various forms of costs and rewards in today's Mobile Content Ecosystems (MCEs) comprising of the network operators, content providers, and the end-users. The research involves: 1) general formulation of cost-reward flow among the MCE stakeholders, 2) developing optimal distributed cooperative caching algorithms, 3) characterizing the impacts of network, user and object dynamics, 4) investigating the impacts, and developing mechanism for controlling non-cooperation in the ecosystems, and finally 5) developing a prototype Social Wireless Network for tracking human mobility in the context of cooperative network caching. Impacts of this research include a potential transformation of the area of object life-cycle management in Social Wireless Networks with an end-goal of network capacity and cost-revenue management in today's Mobile Content Ecosystems. This research can be considered as a key enabler for the emerging social network applications and how they can be symbiotically supported by the cellular and short range wireless network infrastructure.

该项目为社交无线网络(SWNET)中的协作对象缓存开发了一种变革性的机制。其关键思想是通过短距离WiFi风格的无线链路在移动设备上形成的SWNET中智能地存储用户对象，从而减轻运营商3G/4G网络中的无线带宽压力。适用的用户对象将包括手机应用程序、MP3音乐、视频剪辑、新闻项目、书籍章节和研究论文。该项目的主要研究目标是开发一个通用缓存框架，用于管理当今移动内容生态系统(MCE)中的各种形式的成本和回报，该生态系统由网络运营商、内容提供商和最终用户组成。研究内容包括：1)研究MCE利益相关者之间的成本-回报流程，2)开发最优的分布式协作缓存算法，3)表征网络、用户和对象动态的影响，4)研究这些影响，并开发控制生态系统中非合作的机制，最后5)在协作网络缓存的背景下开发用于跟踪人类移动性的原型社交无线网络。这项研究的影响包括社交无线网络中对象生命周期管理领域的潜在变革，最终目标是在当今的移动内容生态系统中进行网络容量和成本-收入管理。这项研究可以被认为是新兴社交网络应用以及如何通过蜂窝和短距离无线网络基础设施共生支持这些应用的关键推动因素。
