Cognitive radio (CR) technology offers the possibility of an increase in spectrum utilization efficiency to resolve the prevalent spectrum scarcity problem. The economic survival of secondary spectrum markets (SSMs) is heavily dependent on the sharing of both the licensed spectrum and spectrum infrastructure by primary licensed operators (PLOs). In this research, an automated pricing model using a blockchain token called the spectrum dollar has been implemented for secondary radio spectrum trade. The use of spectrum dollars enables noncash-based secondary spectrum trade among PLOs based on a floor-and-trade rule. The pricing of spectrum dollars and the associated revenue shares are based on the underlying secondary spectrum trading behaviours of PLOs. PLOs that do not contribute enough secondary spectra to the SSM (to satisfy demand) suffer a loss proportional to the difference between their earned revenues and the specified floor value in the SSM. The secondary spectrum trade is assumed to be centrally managed by a spectrum broker, which announces the floor value for each bidding period while ensuring nonnegative revenue for the market itself. The use of the spectrum dollar along with the floor-and-trade methodology eliminates the possibilities for economic malpractice by PLOs that could increase spectrum reuse costs. In addition, the floor value provides automatic regulatory control to ensure the economic viability and prevent the technological hijacking of future SSMs.

下一代移动网络中二级频谱市场的基于区块链令牌的交易模型

认知无线电(CR)技术提供了提高频谱利用效率以解决普遍频谱稀缺问题的可能性。二级频谱市场(SSM)的经济生存在很大程度上取决于一级许可运营商(PLO)对许可频谱和频谱基础设施的共享。在这项研究中,使用了名为频谱美元的区块链令牌的自动定价模型已实现用于二次无线电频谱交易。频谱美元的使用允许基于最低交易规则的PLO之间基于非现金的二级频谱交易。频谱美元和相关收入份额的定价基于PLO的基础二级频谱交易行为。没有为SSM贡献足够的次级光谱(以满足需求)的PLO遭受的损失与他们的收入和SSM中指定的底价之间的差成比例。假定二级频谱交易由频谱经纪人集中管理,频谱经纪人宣布每个投标期的底价,同时确保市场本身的非负收入。频谱美元与固定交易方法一起使用,消除了PLO可能因经济不当行为而增加频谱复用成本的可能性。此外,底价提供了自动监管控制,以确保经济可行性并防止未来SSM的技术劫持。假定二级频谱交易由频谱经纪人集中管理,频谱经纪人宣布每个投标期的底价,同时确保市场本身的非负收入。频谱美元与固定交易方法一起使用,消除了PLO可能因经济不当行为而增加频谱复用成本的可能性。此外,底价提供了自动监管控制,以确保经济可行性并防止未来SSM的技术劫持。假定二级频谱交易由频谱经纪人集中管理,频谱经纪人宣布每个投标期的底价,同时确保市场本身的非负收入。频谱美元与固定交易方法一起使用,消除了PLO可能因经济不当行为而增加频谱复用成本的可能性。此外,底价提供了自动监管控制,以确保经济可行性并防止未来SSM的技术劫持。频谱美元与固定交易方法一起使用,消除了PLO可能因经济不当行为而增加频谱复用成本的可能性。此外,底价提供了自动监管控制,以确保经济可行性并防止未来SSM的技术劫持。频谱美元与固定交易方法一起使用,消除了PLO可能因经济不当行为而增加频谱复用成本的可能性。此外,底价提供了自动监管控制,以确保经济可行性并防止未来SSM的技术劫持。
