项目摘要

Database-driven dynamic spectrum sharing (DSS) is a key enabling technical paradigm approved by FCC for increasing wireless spectrum access. In such a system, a geo-location database administrator (DBA) accepts registrations from primary users and determines spectrum availability, and secondary users are all required to inquire the DBA about the availability of any interested spectrum before using it. An effective approach to improve the spectrum-estimation accuracy in database-driven DSS systems is to deploy a small number of dedicated spectrum sensors at strategic locations and outsource most spectrum-sensing tasks to ubiquitous mobile users. This approach is not only highly feasible given the wide penetration of increasingly powerful mobile devices into everyday life and the foreseeable prevalence of DSS in future mobile communication systems, but also expected to be much more cost-effective than deploying a large-scale network of dedicated distributed spectrum sensors. This project is to investigate several fundamental security and privacy challenges associated with database-driven DSS systems armed with spectrum-sensing outsourcing. Specifically, there are four main thrusts in this project: (1) secure radio environment map construction in the presence of false spectrum measurements; (2) incentive-compatible and differentially-private mechanisms for crowdsourced spectrum sensing; (3) physical-layer secondary user authentication techniques for spectrum misuse detection; and (4) performance evaluation through a combination of measurement campaign, simulation study, prototyping, and experimentation. The project will actively channel the research results into development of undergraduate and graduate curricula, engage undergraduate and under-represented students into research, and include outreach activities to K-12, underrepresented, and oversea students as well as the local military community.

数据库驱动的动态频谱共享(DSS)是FCC批准的增加无线频谱接入的关键使能技术范式。在这样的系统中，地理位置数据库管理员(DBA)接受主用户的注册并确定频谱可用性，而次用户在使用任何感兴趣的频谱之前都被要求询问DBA任何感兴趣的频谱的可用性。在数据库驱动的DSS系统中，提高频谱估计精度的有效方法是在战略位置部署少量专用频谱传感器，并将大部分频谱感知任务外包给无处不在的移动用户。考虑到日益强大的移动设备在日常生活中的广泛渗透以及DSS在未来移动通信系统中的可预见普及，这种方法不仅是高度可行的，而且预计比部署大规模的专用分布式频谱传感器网络更具成本效益。该项目将调查与配备频谱感知外包的数据库驱动的DSS系统相关的几个基本的安全和隐私挑战。具体地说，该项目有四个主要方面：(1)在存在虚假频谱测量的情况下构建安全的无线电环境地图；(2)众包频谱感知的激励兼容和差异私有机制；(3)用于频谱滥用检测的物理层二次用户认证技术；以及(4)通过测量活动、模拟研究、原型和实验相结合的性能评估。该项目将积极将研究成果用于制定本科生和研究生课程，让本科生和任职人数不足的学生参与研究，并包括面向K-12、任职人数不足的学生、海外学生以及当地军界的外联活动。
