Collaborative Research: NECO: A Market-Driven Approach to Dynamic Spectrum Sharing

为了应对当前频谱使用的低效率，世界各地的监管机构正在探索通过允许在广泛的时空尺度范围内灵活的动态频谱接入（DSA）来放松对频谱市场的监管的方法。无线电技术的最新进展推动了这一趋势。为了使DSA实现其经济和社会影响的承诺，基于DSA的无线服务必须在商业上取得成功，并且有形的频谱市场必须得到技术的支持。该研究项目将为蜂窝网络建立一个现实的DSA架构，由适当的市场机制以综合的方式支持，在技术上和经济上都是可行的和有效的。这是跨越无线网络和系统、算法、经济学、仿真和建模领域的真正跨学科方法，其通过（i）各种市场实体的现实建模（即，买方、卖方和市场机制），（ii）基于创新和现实的人口动态模型的动态频谱需求和出价，以及（iii）具有可证明的性能保证的新的强大的市场清算机制。这些结果将通过大规模模拟和可重构无线电硬件的原型试验台进行验证。除了在跨学科教育中培养新的主题外，该项目还将提供对市场驱动的频谱共享的见解，为政策制定者提供有用的工具，并最终指导DSA技术中的频谱政策决策。这反过来又将为无线频谱的使用开辟新的商机。

To counter the inefficiencies of the current spectrum usage, regulatory bodies, all over the world, are exploring ways to deregulate the spectrum market by allowing flexible dynamic spectrum access (DSA) in a broad range of spatio-temporal scale. Recent advances in radio technology have given an impetus to this trend. For DSA to fulfill its promise of economic and societal impact, wireless services based on DSA must be commercially successful, and a tangible spectrum market must evolve that can be supported by technology. This research project will build a realistic DSA architecture for cellular networks supported by appropriate market mechanisms in an integrated fashion that is both technically and economically viable and efficient. This is a truly trans-disciplinary approach spanning the fields of wireless networking and systems, algorithmics, economics, simulation and modeling, which leads to a deeper understanding of the dynamics of the spectrum market by (i) realistic modeling of various market entities (i.e., buyers, sellers, and the market mechanisms), (ii) dynamic spectrum demands and bids based on innovative and realistic population dynamics models, and (iii) new and robust market clearing mechanisms with provable performance guarantees. The results will be validated using large-scale simulations, and experiments on a prototype test bed with reconfigurable radio hardware. In addition to fostering new topics in trans-disciplinary education, this project will offer insights into market driven spectrum sharing, provide useful tools for policymakers, and ultimately guide spectrum policy decisions in DSA technology. This will, in turn, open up new business opportunities in the use of wireless spectrum.
