HySIM：TV白空间网络的混合频谱和信息市场
HySIM: A Hybrid Spectrum and Information Market for TV White Space Networks
摘要：
我们提出了一个混合频谱和信息市场的数据库辅助电视空白空间网络，其中的地理位置数据库作为一个频谱市场平台和信息市场平台。我们研究了数据库运营商，频谱许可证持有者和未授权用户之间的互动系统，使用三层分层模型。在第一层，数据库和被许可方协商被许可方使用频谱市场平台支付的佣金费用。在第二层，数据库和被许可方竞争向未许可用户出售信息或频道。在第三层中，未授权用户确定他们是否应该从被许可方购买授权信道的独占使用权，或者从数据库购买关于未授权信道的信息。分析这样一个三层模型是具有挑战性的，因为在信息市场中，正的和负的网络外部性并存。我们描述了网络外部性如何影响所有参与方的均衡行为。我们的数值结果表明，建议的混合市场可以提高网络利润高达87%，与纯信息市场相比。同时，实现的网络利润非常接近协调基准解决方案（差距小于4%，在我们的模拟）。
英文摘要：
We propose a hybrid spectrum and information market for a database-assisted TV white space network, where the geo-location database serves as both a spectrum market platform and an information market platform. We study the inter- actions among the database operator, the spectrum licensee, and unlicensed users systematically, using a three-layer hierarchical model. In Layer I, the database and the licensee negotiate the commission fee that the licensee pays for using the spectrum market platform. In Layer II, the database and the licensee compete for selling information or channels to unlicensed users. In Layer III, unlicensed users determine whether they should buy the exclusive usage right of licensed channels from the licensee, or the information regarding unlicensed channels from the database. Analyzing such a three-layer model is challenging due to the co-existence of both positive and negative network externalities in the information market. We characterize how the network externalities affect the equilibrium behaviours of all parties involved. Our numerical results show that the proposed hybrid market can improve the network profit up to 87%, compared with a pure information market. Meanwhile, the achieved network profit is very close to the coordinated benchmark solution (the gap is less than 4% in our simulation).
