The emerging cognitive radio (CR) technology provides new solutions to the wireless service business. A CR-capable service provider can acquire spectrum on demand from the secondary spectrum market to avoid paying the huge spectrum licensing fees, significantly lowering the threshold of entry to the wireless business. As a result, it is foreseeable that small and local secondary wireless service providers (SSPs) will flourish, transforming the wireless business from one dictated by few giant carriers to a much more competitive marketplace. Existing secondary spectrum market models mainly consider a market comprised by big SSPs, where every SSP is assumed to have sufficient secondary radio resource and coverage to independently service end users. In practice, however, these models inevitably exclude the large number of small and local SSPs that do not have enough resource and coverage to independently satisfy the demand of end users (e.g., for high-rate access or long-range routing) from the market, leading to reduced market competitiveness, and henceforth compromised market efficiency. This project will investigate a novel competition-and-collaboration spectrum market framework, whereby small and local SSPs will collaborate in providing service to retain more market shares, better profitability, stronger market competitiveness, and higher market efficiency. This project, if successful, will significantly advance our understanding on the network economics of the secondary spectrum ecosystem comprised by primary spectrum sellers, SSPs, end users, and human, and will contribute to the real-world deployment of economically feasible and sustainable spectrum market.The proposed research will follow three thrusts. (1) For short-term services, assuming perfect rationality for every player in the market, the secondary spectrum market is first modeled as a spot market. A truthful procurement auction model is proposed to study the optimal market mechanisms and their strategy proofness under a variety of market conditions. (2) For long-term services, the project will study the potential and implication of the futures market, in which service predictability in the time domain is exploited to improve market efficiency, using methods such as option pricing and hedging. (3) The rational-player assumption is released and the project will study the impact of irrationality and human factors on market efficiency using methods from Behavioral Economics. This project will also carry out a comprehensive educational plan to broaden its impact, including integrating research with undergraduate and graduate education, recruiting and outreaching to minority and under-represented students, and efficient dissemination and outreaching to the general public.

新兴的认知无线电（CR）技术为无线服务业务提供了新的解决方案。具有CR能力的服务提供商可以从中期频谱市场收购需求，以避免支付巨额频谱许可费，从而大大降低了进入无线业务的门槛。结果，可以预见的是，小型和本地二级无线服务提供商（SSP）将蓬勃发展，将无线业务从很少的巨型运营商所指示的商业转变为更具竞争性的市场。现有的二级频谱市场模型主要考虑由Big SSP组成的市场，其中每个SSP都被认为具有足够的次级无线电资源和对独立服务最终用户的覆盖范围。但是，实际上，这些模型不可避免地将没有足够的资源和覆盖范围的大量小型和本地SSP排除在市场之外，无法独立满足最终用户的需求（例如，对于高利率访问或长期路由），从而降低了市场竞争力，从而降低了市场效率。该项目将调查一个新颖的竞争和合作频谱市场框架，因此小型和本地SSP将合作提供服务，以保留更多的市场份额，更好的盈利能力，更强的市场竞争力和更高的市场效率。如果成功的话，该项目将大大提高我们对二级生态系统的网络经济学的理解，由初级频谱销售商，SSP，最终用户和人类组成，并将为经济上可行和可持续的光谱市场的现实部署做出贡献。拟议的研究将遵循三个刺激性的研究。 （1）对于短期服务，假设市场上的每个参与者都是完美的合理性，则首先将二级频谱市场建模为现货市场。提出了一个真实的采购拍卖模型，以研究在各种市场条件下的最佳市场机制及其战略证明。 （2）对于长期服务，该项目将研究期货市场的潜力和含义，在这种情况下，使用期权定价和套期保值的方法利用了时间域中的服务可预测性来提高市场效率。 （3）释放了理性游戏假设，该项目将使用行为经济学的方法研究非理性和人为因素对市场效率的影响。该项目还将执行一项全面的教育计划，以扩大其影响力，包括将研究与本科和研究生教育融为一体，向少数群体和代表性不足的学生进行招募和宣传，并有效地传播和向普通公众推出。
