摘要
针对目前单节点频谱感知检测概率低下的问题,提出了一种基于联盟博弈论的频谱感知算法。该算法把联盟博弈论应用到频谱感知算法中,基于简单的合并-分裂准则,根据代价函数、效用函数寻找合适的联盟政策进行结盟,得到最优的联盟。仿真结果表明提出的算法提高了频谱感知的检测概率。
Aiming at solving the problem of low accuracy of spectrum sensing technology,a novel spectrum sensing scheme is proposed in this paper,in which coalition game theory is applied in the spectrum sensing scheme.The scheme is based on the simple combination-splitting criteria,besides according to the cost function,the utility function to find the right alliance policy for the alliance,and get the optimal coalition.The analysis and simulation results show that this method can improve the spectrum sensing efficiency.
