Broadcast media underlying wireless networks enable diverse devices to communicate using shared channels, but also leave them severely exposed to adversaries. Our increased reliance on wireless networks for connectivity to the cyber-infrastructure, and for monitoring our physical infrastructure, has opened the door for sophisticated denial-of-service attacks with potentially devastating effects on our economy and homeland security.This project pursues a new game-theoretic framework for agile and resilient wireless systems. The framework models the interaction between communicating nodes and adversaries as two-player games, with strategies defined by various protocol choices and cross-layer attacks. A central thesis of this game-theoretic paradigm is that resilient wireless systems need to be highly agile, rapidly mixing strategies to thwart adaptive attackers.The research methodology underlying this project is threefold. The first component formulates games capturing complex interactions between communicating nodes and adversaries across basic building blocks of wireless systems. The second component concerns optimization problems and equilibria associated with these games. The final component realizes the architecture and solutions in tworeal-world prototypes: a Linux-based platform for 802.11 networks, and a Software-Defined Radio platform for studying more sophisticated mechanisms.This project addresses the critical need of protecting our wireless infrastructure from DoS attacks. The research conducted will lead to (a) new game-theoretic analysis of wireless systems quantifying vulnerabilities and worst-case scenarios, and identifying promising methods to thwart such attacks; (b) highly agile cross-layer protocols that are resilient to the most adaptive adversaries; (c) new tools for implementing and evaluating these protocols in real-world systems.

作为无线网络基础的广播媒体使各种设备能够使用共享信道进行通信，但也使它们严重暴露于对手。我们越来越依赖无线网络来连接网络基础设施以及监控我们的物理基础设施，这为复杂的拒绝服务攻击打开了大门，这可能会对我们的经济和国土安全产生毁灭性影响。该项目追求一个新的游戏理论框架，用于敏捷和有弹性的无线系统。该框架将通信节点和对手之间的交互建模为两人游戏，并通过各种协议选择和跨层攻击定义策略。这个博弈论范式的一个中心论点是，弹性无线系统需要高度敏捷，快速混合策略，以挫败自适应攻击者。第一个组成部分制定游戏捕捉通信节点和对手之间的复杂的相互作用，在无线系统的基本构建块。第二部分涉及与这些游戏相关的优化问题和均衡。最后一个组件实现了两个真实世界原型的架构和解决方案：一个基于Linux的802.11网络平台，和一个软件定义的无线电平台，用于研究更复杂的机制。 进行的研究将导致（a）新的博弈论分析的无线系统量化的漏洞和最坏的情况下，并确定有前途的方法来挫败这种攻击;（B）高度灵活的跨层协议，是最适应对手的弹性;（c）新的工具，在现实世界的系统中实施和评估这些协议。
