Opportunistic spectrum access (OSA) is at the core of the cognitive radio technologies with the focus on improving spectrum utilization efficiency and reliability. Despite the benefits, existing OSA protocols suffer from their deterministic nature and cannot prevent an ill-intended jammer from disrupting legitimate communications. A cognitive jammer can always effectively jam the idle channels by exploiting public-available channel statistics and causes serious spectrum underutilization. This project addresses the challenge of establishing robust anti-jamming communication in cognitive radio networks (CRNs) through a multiple-line of defense approach. The research considers a variety of network environments and integrates defense technologies from different dimensions, including adaptive uncoordinated frequency hopping (AUFH), power control, and signal processing. The defense approach enables both reactive and proactive protections, from evading jammers to competing against jammers, and to expelling jamming signals, and thus ensures robust user communications in CRNs. The research in this project has a potential to significantly advance the state-of-the-art and develop innovative and sophisticated defense strategies using the proposed multiple lines of defense approach. The proposed solutions will contribute towards eventually building robust and dependable CRNs that are critical to the future communication systems. The project will also contribute directly to the curriculum development, teaching, student supervising and future security engineer training. Major results of this project will be disseminated through presentations, publications, as well as online materials in the forms of tutorials and software packages.

机会频谱访问（OSA）是认知无线电技术的核心，重点是提高光谱利用率效率和可靠性。尽管有好处，但现有的OSA协议却遭受了确定性的性质，并且无法阻止不感激的干扰器破坏合法的沟通。认知干扰器始终可以通过利用公共可用的渠道统计数据来有效地堵塞闲置通道，并导致严重的频谱不足。该项目解决了通过多线防御方法在认知无线网络（CRN）中建立强大的反杀伤沟通的挑战。该研究考虑了各种网络环境，并整合了来自不同维度的防御技术，包括自适应不协调的频率跳跃（AUFH），功率控制和信号处理。辩护方法可以使反应性和主动保护措施，从逃避干扰者到与干扰者竞争，并驱逐干扰信号，从而确保CRN中强大的用户通信。该项目中的研究有可能通过拟议的多种防御方法显着提高最先进的最先进并制定创新和复杂的防御策略。拟议的解决方案将有助于最终建立对未来通信系统至关重要的强大而可靠的CRN。该项目还将直接为课程发展，教学，学生监督和未来的安全工程师培训做出贡献。该项目的主要结果将通过演讲，出版物以及教程和软件包形式的在线材料进行传播。
