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。最近开发的一项技术，称为机会编码，可以大大提高无线网络的效率。然而，基于机会编码（OCB）的无线网络中的协作和安全问题还没有得到足够的重视。在这里，合作问题是无线网络中存在的自组织节点所带来的问题，而安全问题则是存在的对抗节点所带来的问题。本文的工作就是设计和实现能够为OCB无线网络提供协作和安全保障的解决方案。本文的研究工作可以分为三个问题领域，即合作问题、安全问题以及合作与安全的相互作用。知识成果：本研究成果将显著提高OCB无线网络的协作性和安全性。此外，这些结果也将有更广泛的理论利益，因为要开发的技术的一部分将适用于经济激励问题在其他settings.Broader影响：首先，开发的技术解决方案将贝内社会，因为它们使得有可能广泛部署OCB无线网络的环境与sel ′ sh或敌对节点。第二，这项工作的教育部分将在各级建设合作与安全能力。

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.
