Wi-Fi has emerged as the technology of choice for Internet access. Thus, virtually every smartphone or tablet is now equipped with a Wi-Fi card. Concurrently, and as a means to maximize spectral efficiency, Wi-Fi radios are becoming increasingly complex and sensitive to wireless channel conditions. The prevalence of Wi-Fi networks, along with their adaptive behaviors, makes them an ideal target for denial of service attacks at a large, infrastructure level.This project aims to comprehensively investigate the resiliency of Wi-Fi networks to smart attacks, and to design and implement robust solutions capable of resisting or countering them. The project additionally focuses on harnessing new capabilities of Wi-Fi radios, such as multiple-input and multiple-output (MIMO) antennas, to protect against powerful adversaries. The research blends theory with experimentation and prototyping, and spans a range of disciplines including protocol design and analysis, coding and modulation, on-line algorithms, queuing theory, and emergent behaviors.The anticipated benefits of the project include: (1) a deep understanding of threats facing Wi-Fi along several dimensions, via experiments and analysis; (2) a set of mitigation techniques and algorithms to strengthen existing Wi-Fi networks and emerging standards; (3) implementation into open-source software that can be deployed on wireless network cards and access points; (4) security training of the next-generation of scientists and engineers involved in radio design and deployment.

Wi-Fi已成为互联网接入的首选技术。因此，几乎每一部智能手机或平板电脑现在都配备了Wi-Fi卡。同时，作为最大化频谱效率的一种手段，Wi-Fi无线电变得越来越复杂，对无线信道条件越来越敏感。Wi-Fi网络的普及，沿着其自适应行为，使其成为大规模基础设施级别的拒绝服务攻击的理想目标。本项目旨在全面调查Wi-Fi网络对智能攻击的弹性，并设计和实现能够抵抗或应对这些攻击的强大解决方案。该项目还专注于利用Wi-Fi无线电的新功能，如多输入多输出（MIMO）天线，以抵御强大的对手。该研究将理论与实验和原型设计相结合，涵盖了协议设计和分析、编码和调制、在线算法、排队论和紧急行为等一系列学科，预期的好处包括：（1）通过实验和分析，从沿着深入了解Wi-Fi面临的威胁;（2）一套缓解技术和算法，以加强现有的Wi-Fi网络和新兴标准;（3）实现到可以部署在无线网卡和接入点上的开源软件中;（4）对参与无线电设计和部署的下一代科学家和工程师进行安全培训。
