基于频谱差异的动态频谱分配博弈算法

基于博弈论的认知无线电动态频谱分配，是目前认知无线电领域研究的热点之一。考虑到频谱差异性，采用古诺博弈(Cournot game)模型，在原有的定价函数中加入频谱相似度矩阵，提出了新的效用函数，使得更接近于实际网络环境。性能分析表明，考虑了频谱差异性的分配算法较原来算法更具多样性，适合实际网络分配。

A game algorithm of dynamic spectrum allocation based on spectrum difference

Game theory-based dynamic spectrum allocation of cognitive radio is one of the hot research of cognitive radio. Taking into account differences of the spectrum, using a Cournot game model, and adding the spectral similarity matrix to the original pricing function, a new utility function that makes the spectrum allocation more close to the actual network environment is proposed. Performance analysis shows that, the allocation algorithm considering the differences in the spectrum is more diverse than the original algorithm, and is suitable for the actual network.
