NetSE: Small: Cooperation and Security for Opportunistic-Coding-based Wireless Networks

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。最近开发的一种技术，称为机会编码，可以大大提高无线网络的效率。然而，基于机会主义编码（OCB）的无线网络中的协作和安全问题并没有得到足够的重视。这里的协作问题是由于无线网络中存在非对称节点而引入的问题，而安全问题是由于存在对抗节点而引入的问题。本工作旨在设计和实现能够为OCB无线网络提供协作和安全保障的解决方案。研究工作可分为三个问题领域的研究，即合作问题、安全问题和合作与安全的相互作用。这项工作还包括向不同层次的学生传播相关知识。知识价值：这项工作的结果将在协作和安全方面显著改善OCB无线网络。此外，这些结果还将具有更广泛的理论兴趣，因为有待开发的部分技术也将适用于其他环境中的经济激励问题。更广泛的影响：首先，开发的技术解决方案将使社会受益，因为它们可以将OCB无线网络广泛部署到具有独立或对抗节点的环境中。第二，这项工作的教育部分将在各级建立合作与安全的能力。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).A recently developed technology, called opportunistic coding, can greatly improve the e±ciency of wireless networks. However, the problems of cooperation and security in opportunistic-coding-based (OCB) wireless networks have not received su±cient attention. Here cooperation problemsare the problems introduced by the existence of sel¯sh nodes in the wireless networks, while security problems are the problems introduced by the existence of adversarial nodes. This work is to design and implement solutions that can provide cooperation and security guarantees for OCB wireless networks. The research work can be divided into studied of three problem areas, namely the cooperation problems, the security problems, and the interplays ofcooperation and security. The work also includes the dissemination of related knowledge to students at various levels.Intellectual Merit: The results of this work will signi¯cantly improve OCB wireless networks in terms of cooperation and security. Furthermore, these results will also have broader theoretical interests, because a part of the techniques to be developed will be applicable to economic incentivesproblems in other settings as well.Broader Impacts: First, the developed technical solutions will bene¯t the society because they make it possible to widely deploy OCB wireless networks to environments with sel¯sh or adversarial nodes. Second, the educational component of this work will build capacity in cooperation and security at various levels.
