中文摘要：

针对认知无线网络的信道接入问题，为减少在授权信道上次用户与主用户之间的互相干扰，并提高信道利用效率，提出一种基于动态频谱博弈约束机制的认知无线网络信道选择算法。首先提出一种博弈约束机制，分析次用户在利用频谱资源时所付出的成本以及所收获的效益，得出频谱分配博弈的约束函数，使次用户所选择的频谱能够尽可能地被利用并产生效益，提高频谱资源的利用率。为了选择更好的接入信道，采用基于信道利用率、丢包率、功率情况这三种性能指标的信道选择方法来选择授权的空闲信道。实验仿真及对比结果表明，该算法相比基于时间序列预测方法和基于竞争协作频谱接入方法，在减少信道接入的延迟干扰、提高信道利用率上具有更好的效果。

英文摘要：

For the problem that cognitive wireless network channel access, to reduce interference between the channels au- thorized by the primary user of the second user, and increase the efficiency of channel utilization, this paper proposed a cogni- tive radio network channel selection algorithm based on dynamic spectrum game binding mechanism. First of all, it proposed a game constraint mechanism to analyze secondary users in the use of spectrum resources as well as the cost to harvest the bene- fits, constraints derived function spectrum allocation game, the spectral time selected by the user can be utilized as much as possible and to produce benefits improve the utilization of spectrum resources. Secondly, in order to choose a better access channel, channel selection method based on channel utilization, packet loss rate, power situation of these three performance indicators to select authorized idle channel. Simulation and comparison of experimental results show that the algorithm based on time series prediction method compared to the competition and cooperative spectrum access based method to reduce the delay in channel access interference and improve with better results on the channel utilization.
