Worldwide increase in spectrum usage has made efficient spectrum sharing an important economic topic. One way to share the spectrum is to allow secondary users (SUs) to dynamically utilize the spectrum that primary users (PUs) do not use at a particular time and location. It is vital to design spectrum management mechanisms to promote efficiency, fairness, and privacy while preventing collusion. Efficiency ensures that the spectrum users who value the spectrum the most end up with it. Competition preservation ensures that collusion among secondary spectrum buyers is prevented. In particular, collusive behaviors among SUs can result in a lower price awarded to the PU. In the long run, the PU will be less willing to share or sell the spectrum, resulting in this important resource not being fully utilized. Privacy establishes that a spectrum user’s private information regarding location or pricing is not revealed, which prevents malicious attacks to a broadband provider or consumer to avoid broadband outages or interference. Fairness establishes that similar spectrum users are treated similarly, thus creating trust in spectrum sharing. The research team employs methods from economics and computer science to develop novel spectrum sharing mechanisms that take account of all four properties. The three main objectives are (1) to construct mechanisms that preserve competition while maintaining efficiency, (2) to design privacy preservation schemes that ensure efficiency, and (3) to identify economic approaches and algorithms that meet all four properties. Current spectrum sharing algorithms generally focus on either maintaining efficiency or privacy. The researchers consider both of these properties at the same time as well as competition preservation and fairness. The research enhances the knowledge of those studying auctions who are interested in privacy preservation, fairness, and coalition prevention as well as those interested in the implementation of such mechanisms. In particular, in Thrust 1, new auction mechanisms include location, in consideration of negotiation power and information availability, to increase spectral efficiency and prevent collusion. Furthermore, privacy preservation is a topic that has become popular recently although there are few privacy preservation mechanisms in the economic literature. Thrust 2 adds to the knowledge of how to achieve both higher spectral utilization and user location privacy in a game-theoretic framework. Novel algorithms for location obfuscation mechanisms and utility functions will be more suitable for spatial spectrum sharing with directional transmissions. Thrust 3 focuses on new economic approaches and algorithms will ensure joint competition preservation, efficiency, fairness, and privacy in spatial spectrum.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

全球范围内频谱使用的增加使得频谱共享高效成为一个重要的经济主题，共享频谱的一种方法是允许次要用户（SU）动态地利用主要用户（PU）在特定时间和地点不使用的频谱。设计频谱管理机制以提高效率、公平性和隐私性，同时防止串通，这一点至关重要。效率确保最看重频谱的频谱用户最终能够获得频谱，从而防止二级频谱购买者之间的串通。特定的串通行为SU 之间的竞争可能会导致 PU 获得较低的价格。从长远来看，PU 将不太愿意共享或出售频谱，从而导致这一重要资源没有得到充分利用。位置或定价不会被泄露，这可以防止对宽带提供商或消费者的恶意攻击，从而避免宽带中断或干扰。公平性规定相似的频谱用户受到类似的对待，从而建立对频谱共享的信任。科学开发新颖的频谱共享考虑到所有四个属性的机制是（1）构建在保持效率的同时保持竞争的机制，（2）设计确保效率的隐私保护方案，以及（3）确定经济方法和算法目前的频谱共享算法通常侧重于保持效率或隐私，同时考虑竞争保护和公平性。隐私保护、公平和联盟预防以及对实施感兴趣的人特别是，在推力1中，考虑到协商能力和信息可用性，新的拍卖机制包括位置，以提高频谱效率并防止串通。此外，隐私保护是最近流行的话题，尽管很少。 Thrust 2 增加了关于如何在博弈论框架中实现更高频谱利用率和用户位置隐私的知识。位置混淆机制和效用函数的新颖算法将更适合空间频谱共享。 Thrust 3 专注于新的经济方法和算法，将确保空间频谱中的联合竞争保护、效率、公平性和隐私。该奖项授予 NSF 的法定使命，并通过使用基金会的智力优势和更广泛的评估被认为值得支持。影响审查标准。
