TWC SBE: Medium: Collaborative: Dollars for Hertz: Making Trustworthy Spectrum Sharing Technically and Economically Viable

2010年国家宽带计划(NBP)强调了频谱作为经济增长催化剂的关键作用。NBP面临的一个挑战是在存在来自任何来源的恶意传输造成的干扰的情况下实现最佳频谱共享，特别是共享该频谱的二次用户。这个复杂的问题横跨无线技术、行业经济、国际标准和监管政策。这个跨学科、多大学合作的项目研究了从算法到执法的许多方面的问题。研究人员研究(1)事前频谱规则执行机制(即，预防性)，例如通过政策推理者进行频谱访问控制；(2)事后频谱规则执行计划(即，惩罚性)，以及使用加密承诺进行政策一致性监控；(3)事后执行计划，可以唯一地识别流氓发射机；以及(4)通过不同的执行计划共享频谱的经济可行性。该项目提供了广泛的教育和行业外展活动，以迅速将研究进展纳入课程和大学-行业合作伙伴关系。具体地说，调查人员将在一年一度的弗吉尼亚理工大学无线研讨会和暑期学校上提供短期课程和教程，并通过弗吉尼亚理工学院和州立大学的NSF工业与大学合作研究中心(I/UCRC)广泛传播调查结果。

The critical role of spectrum as a catalyst for economic growth was highlighted in the 2010 National Broadband Plan (NBP). A challenge for the NBP is realizing optimal spectrum sharing in the presence of interference caused by rogue transmissions from any source, but particularly secondary users who share the spectrum. This complex problem straddles wireless technology, industrial economics, international standards, and regulatory policy. This interdisciplinary, multi-university collaborative project studies the many dimensions of the problem from algorithms to law enforcement. The investigators study (1) ex-ante spectrum rule enforcement mechanisms (i.e., preventive) such as spectrum access control via policy reasoners, (2) ex-post spectrum rule enforcement schemes (i.e., punitive) with policy conformance monitoring that employ cryptographic commitments, (3) ex-post enforcement schemes that can uniquely identify rogue transmitters, and (4) the economic viability of spectrum sharing with different enforcement schemes.The project provides a broad range of education and industry outreach activities in order to rapidly insert research advances into curriculum and university-industry partnerships. Specifically, the investigators will present short courses and tutorials at the annual Virginia Tech Wireless Symposium and Summer School, and widely disseminate findings through NSF Industry & University Collaborative Research Centers (I/UCRC) at the Virginia Polytechnic Institute and State University.
