NeTs: Small: Economic Incentives for P2P: Theory and Design

尽管P2P已经证明了它是分布式应用的一个可行的架构范例，但未来P2P应用的成功最终取决于说服用户自愿使用这些资源。在这个项目中，两个相互关联的P2P激励范式正在调查中。在第一种模式中，称为网络异步双边交易（NABT），每个用户都有一组在线朋友。用户可以使用当地货币和债务限额与直接朋友进行异步交易。NABT还允许交易通过中介机构进行。对于文件共享，NABT几乎与完美经济一样高效，所有用户都可以直接相互交易。研究还旨在扩展NABT，开发异构P2P资源市场的设计和理论。 第二种模式称为封闭的P2P社区，使用轻量级的集中式银行基础设施。这里的重点是设计和分析一类新的强大的，但轻量级的基于货币的激励计划。 博弈论被应用于设计激励机制，优化交易吞吐量的不同P2P市场和定价理论被用来研究在封闭的P2P社区的定价动态。 发现和驱逐共谋者的新方法也在开发中。两种激励模式的原型将被构建。该项目将提供一个新的P2P计算模式的框架。 它将涉及本科生和研究生，特别是少数民族学生。与工业界的互动将通过纽约大学-保利的CATT中心来促进。 教育材料将开发和传播的本科生和研究生水平的网络课程教授的PI在纽约大学理工学院。

Although P2P has proven itself as a viable architectural paradigm for distributed applications, the success of future P2P applications ultimately depends on convincing users to volunteer these resources. In this project, two inter-related P2P incentive paradigms are under investigation. In the first paradigm, called Networked Asynchronous Bilateral Trading (NABT), each user has a set of online friends. Users can trade asynchronously with direct friends using local currency and a debt limits. NABT also allows trades to pass through intermediaries. For file sharing, NABT is almost as efficient as a perfect economy, where all users can trade directly with each other. Research is also aimed at extending NABT, developing designs and theories for heterogeneous P2P resource markets. The second paradigm, called Closed P2P Communities, uses a lightweight centralized banking infrastructure. Here the focus is on designing and analyzing a new class of powerful, but lightweight currency-based incentive schemes. Game theory is being applied to design incentive mechanisms that optimize deal throughput for diverse P2P markets and pricing theory is used to study the pricing dynamics in closed P2P communities. Novel approaches for detecting and evicting colluders are also under development. Prototypes for both incentive paradigms will be constructed. The project will provide a framework for a new P2P computing paradigm. It will involve undergraduate and graduate students, especially minority students. Interactions with industry will be facilitated through the CATT center at NYU-Poly. Educational material will be developed and disseminated for undergraduate and graduate level networking courses taught by the PIs at NYU-Poly.
