Cognitive radio and dynamic spectrum access can reform the way that radiofrequency spectrum is accessed. Problems of spectrum scarcity, coexistence, and unreliable wireless communication that affect industrial wireless networks can be addressed. In this paper, a game theoretic dynamic spectrum access algorithm that improves upon on a hedonic coalition formation algorithm for spectrum sensing and access is presented. The modified algorithm is tailored for faster convergence and scalability and makes use of a novel simultaneous multichannel sensing and access technique. Results to demonstrate the performance improvements of the adapted algorithm are presented and the use of different decision rules are investigated revealing that a conservative decision rule for exploiting spectrum opportunities performs better than an aggressive decision rule in most scenarios. The algorithm that was developed could be a key enabler for future cognitive radio networks.

认知无线电网络的快速融合协作动态频谱接入


认知无线电和动态频谱接入可以改革射频频谱的接入方式。影响工业无线网络的频谱稀缺、共存和不可靠无线通信问题可以得到解决。本文提出了一种博弈论动态频谱访问算法，该算法改进了用于频谱感知和访问的享乐联盟形成算法。修改后的算法专为更快的收敛和可扩展性而定制，并利用了新颖的同时多通道感测和访问技术。给出了证明自适应算法性能改进的结果，并对不同决策规则的使用进行了研究，结果表明，在大多数情况下，利用频谱机会的保守决策规则比激进的决策规则表现更好。开发的算法可能成为未来认知无线电网络的关键推动者。
