摘　　要：结合博弈论,论文首先提出一种基于博弈论的适用于认知Ad Hoc网络的公共信道建立算法,但该算法并不保证认知用户总是能够收敛到同一公共信道.随后,论文提出两种可收敛的改进算法.仿真结果表明改进算法能够适应不同的网络环境,使用户通过博弈过程最终收敛到同一个空闲信道上,完成公共信道的建立,并能在一定程度上保证信道质量.最后,论文对算法的收敛性进行了论证.A Common Channel Establishing Algorithm Based on Game Theory in Ad Hoc Cognitive Radio Network（CRN） is proposed in this paper.However,this algorithm cannot guarantee that the cognitive radios converge to the same common channel.Then two improved algorithms which can guarantee convergence are proposed.The simulation results demonstrate that two improved algorithms can adapt to different scenarios and establish the common channel among Cognitive Users successfully through the gaming process.The channel quality can be ensured as well.In the end,this paper gives the argumentation on the algorithms＇ convergence.
