The proliferation of wireless technology constitutes one of the most remarkable success stories in the history of human intervention. This growth however raises the question of whether technology will capitulate to its own success owing to the scarcity of spectrum. Fortunately the problem is more artificial than fundamental: the scarcity has been precipitated by the exclusive licensing model, while large swaths of licensed spectrum remain underutilized. A conjecture therefore is that unlicensed access of idle (but licensed) spectrum, commonly referred to as secondary spectrum access, can help avert the impending crisis. This however can only be realized if secondary access is profitable for the license holders. This is the main motivation behind this research, which seeks to design incentives to induce license holders to allow secondary access. Specifically, the research studies a free secondary market where the licensed and unlicensed users trade access rights based on bilateral agreements, and seek to optimize their interaction strategies. The resulting decision problems are analyzed using tools from game theory, optimization, graph theory and stochastic control. The profit perspective adopted in this research incentivizes greater participation of wireless carriers in the secondary markets, enabling a quantum leap in more efficient spectrum utilization. Students at both undergraduate and graduate levels are trained in subjects from wireless technology to game theory and optimization theory. This research will generate algorithms for computing the decision strategies of the license holders. They will be evaluated through rigorous analysis and extensive simulations. Results will be disseminated through conferences and journals.

无线技术的普及是人类干预历史上最引人注目的成功故事之一。然而，这种增长提出了一个问题：技术是否会因为频谱的稀缺而屈服于自身的成功。 幸运的是，这个问题更多是人为的，而不是根本性的：独家许可模式加剧了稀缺性，而大片许可频谱仍未得到充分利用。 因此，一个推测是，未经许可的空闲（但已获得许可）频谱的访问（通常称为辅助频谱​​访问）可以帮助避免即将发生的危机。 然而，只有当二次访问对许可证持有者有利时才能实现这一点。这是这项研究背后的主要动机，旨在设计激励措施来诱导许可证持有者允许二次访问。 具体来说，该研究研究了一个自由的二级市场，其中许可和未许可的用户根据双边协议交易访问权，并寻求优化他们的交互策略。 使用博弈论、优化、图论和随机控制等工具来分析由此产生的决策问题。本研究采用的利润视角激励无线运营商更多地参与二级市场，从而实现更高效频谱利用的巨大飞跃。 本科生和研究生都接受无线技术、博弈论和优化理论等科目的培训。 这项研究将生成用于计算许可证持有者决策策略的算法。他们将通过严格的分析和广泛的模拟进行评估。 结果将通过会议和期刊传播。
