NeTS: Small: A Practical and Efficient Trading Platform for Dynamic Spectrum Distribution

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。历史静态频谱分配导致了严重的频谱短缺。虽然新的知名无线技术迫切需要频谱，但在当前所有者的大部分时间里，大量频谱仍处于闲置状态。在适当的经济激励下，基于开放市场的频谱再分配可以消除人为的短缺。该项目开发了S-TRADE，这是一个拍卖驱动的频谱交易平台，以实现频谱市场。S-TRADE与传统的fcc风格的频谱拍卖有很大不同，后者只针对少数大公司，需要数月或数年才能完成。相反，S-TRADE为许多小型参与者提供服务，并实现实时频谱交易。本质上，S-TRADE有选择地从供应商那里购买闲置的频谱片段，并将其出售给大量符合其个人需求的买家。通过在时间和空间上有效地复用频谱供需，该市场还显著提高了频谱利用率。S-TRADE的设计重点是实现频谱复用/重用，以提高频谱利用率，同时保证经济稳健性，以鼓励参与者参与并最大限度地减少市场操纵。本课题致力于将动态频谱分配新算法与经济机制设计紧密结合。研究成果加深了我们对频谱分配方式和经济学在频谱分配中的作用的理解。通过将经济学机制设计与无线网络相结合，该项目成为本科生和研究生跨学科培训项目的重要组成部分。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Historical static spectrum assignment has led to a critical spectrum shortage. While new prominent wireless technologies starve for spectrum, large chunks of spectrum remain idle most of the time under their current owners. With proper economic incentives, spectrum redistribution based on an open market can eliminate the artificial shortage. This project develops S-TRADE, an auction-driven spectrum trading platform to implement the spectrum marketplace. S-TRADE differs significantly from conventional FCC-style spectrum auctions that target only a few large corporate players and take months or years to conclude. Instead, S-TRADE serves many small players and enables on-the-fly spectrum transactions. In essence, S-TRADE selectively buys idle spectrum pieces from providers and sells them to a large number of buyers matching their individual demands. By effectively multiplexing spectrum supply and demand in time and space, the proposed marketplace also significantly improve spectrum utilization. The design of S-TRADE focuses on achieving spectrum multiplexing/reuse to improve spectrum utilization while guaranteeing economic robustness to encourage player participation and minimize market manipulation. This project focuses on tightly integrating novel algorithms of dynamic spectrum allocation with economic mechanism design. The research outcomes deepen our understanding of the way spectrum should be distributed and the role of economics in distributing it. By integrating economics mechanism design with wireless networking, this project forms an integral part of interdisciplinary training programs at both undergraduate and graduate levels.
