论文摘要
本文介绍了以数据为中心的点对点文件共享（DAPES），这是一种具有间歇性连接和用户移动性的方案的数据共享协议。 DAPE提供了一组具有语义上有意义的层次命名抽象，以促进通过本地连接交换文件收集。这使同行可以通过最大化单个传输的效用，以提供大多数连接的同行缺少数据的数据，从而使同行与其他同行的连接时间有限。 DAPE在命名DATA网络（NDN）的顶部运行，并扩展了NDN的以数据为中心的网络层摘要，通过自适应的逐型型转发/抑制机制通过多个无线啤酒花通过多个无线啤酒花实现通信。我们通过在室外校园环境和广泛的模拟中通过现实世界实验评估了DAPE。我们的结果表明，与依赖于基于IP的移动AD-HOC路由的文件共享解决方案相比，DAPES的开销低50-71％，文件共享延迟延迟下降了50-71％。
This paper introduces DAta-centric Peer-to-peer filE Sharing (DAPES), a data sharing protocol for scenarios with intermittent connectivity and user mobility. DAPES provides a set of semantically meaningful hierarchical naming abstractions that facilitate the exchange of file collections via local connectivity. This enables peers to "make the most" out of the limited connection time with other peers by maximizing the utility of individual transmissions to provide data missing by most connected peers. DAPES runs on top of Named-Data Networking (NDN) and extends NDN's data-centric network layer abstractions to achieve communication over multiple wireless hops through an adaptive hop-by-hop forwarding/suppression mechanism. We have evaluated DAPES through real-world experiments in an outdoor campus setting and extensive simulations. Our results demonstrate that DAPES achieves 50-71% lower overheads and 15-33% lower file sharing delays compared to file sharing solutions that rely on IP-based mobile ad-hoc routing.
