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.

广播无线网络的基础媒体使各种设备能够使用共享渠道进行通信，但也使它们严重暴露于对手。我们对无线网络的连通性不断增加，并且为了监视我们的物理基础设施，为复杂的拒绝服务攻击打开了大门，对我们的经济和国土安全有潜在的毁灭性影响。这项项目为敏捷和弹性的无线电系统提供了新的项目。该框架将通信节点和对手之间的相互作用建模为两人游戏，并通过各种协议选择和跨层攻击来定义策略。该游戏理论范式的一个核心论文是，有弹性的无线系统需要高度敏捷，迅速混合策略来阻止自适应攻击者。该项目的基础研究方法是三倍。第一个组件制定了游戏，捕获了无线系统基本构件之间通信节点和对手之间的复杂交互。第二部分涉及与这些游戏相关的优化问题和平衡。最终组件在Tworeal-World原型中实现了架构和解决方案：一个用于802.11网络的基于Linux的平台，以及用于研究更复杂机制的软件定义的无线电平台。该项目解决了保护我们的无线基础架构免受DOS攻击的关键需求。 进行的研究将导致（a）对无线系统的新游戏理论分析，量化漏洞和最坏情况的情况，并确定有望阻止此类攻击的有希望的方法； （b）对最适应性对手有弹性的高度敏捷跨层方案； （c）在实际系统中实施和评估这些协议的新工具。
