CIF: Small: Dynamic Pricing of Interference in Cognitive Radio Networks

电信业正处于重大结构性变革的边缘。在历史上，该行业的监管机构为在可用频谱内使用定义明确的频段分配了许可证。与其他大宗商品不同，频谱的二级市场从未发展起来。技术限制以及法律和法规限制可能是造成这一事实的原因。如今，证据清楚地表明了频谱相对利用不足的情况。认知无线电网络(CRN)是一种新的无线通信模式，旨在更有效地利用频谱。这项研究项目集中在两个重要的技术和监管问题上，必须解决这两个问题，以确保认知无线电网络的成功部署。第一个问题与网络有关-S在没有主用户合作的情况下以分布式方式管理干扰的能力。在这里，研究任务包括从信号处理和算法的角度分析在各种监管限制下的广泛CRN场景下的各种基于价格的动态频谱分配方案。第二个相关问题与频谱二级市场的设计有关。这项研究考虑到特定的频谱共享技术和卖方(即主要用户/主要网络服务提供商(NSP))和买方(即认知用户)的相关行为，对不同的设计选择进行了分析。拟议的工作针对新的模型，以(I)在广泛的CRN范围内促进分布式频谱共享和频谱决策，以及(Ii)为二级频谱市场的运作提供更多的见解，这可能被证明对监管设计有用。

The telecommunications industry is on the verge of major structural change. Historically, the industry's regulator has allocated licenses for the utilization of well-defined bands within the available spectrum. Unlike other commodities, no secondary market for the spectrum has ever developed. Technological limitations as well as legal and regulatory constraints may have contributed to this fact. Today the evidence clearly points to a situation of relative under-utilization of the spectrum. A "cognitive radio network" (CRN) is a new paradigm for wireless communications aimed at enabling a more efficient use of the spectrum. This research project focuses on two significant technical and regulatory issues which must be resolved to ensure successful deployment of cognitive radio networks. The first issue relates to the network?s ability to manage interference in a distributed fashion without cooperation from the primary users. Here, the research tasks include the analysis, from a signal processing and algorithmic point of view, of various price-based schemes for dynamic spectrum allocation in a broad range of CRN scenarios under a variety of regulatory restrictions. The second relevant issue pertains to the design of a secondary market for the spectrum. The research investigates the analysis of various design choices taking into account specific spectrum sharing techniques and the associated behavior of sellers (i.e. primary users/primary network service providers (NSP)) and buyers (i.e. cognitive users).The proposed work targets new models to (i) facilitate distributed spectrum sharing and spectrum decision in a broad range of CRN, and to (ii) provide additional insights into the operation of a secondary spectrum market which could prove useful for regulatory design.
