基于机制设计的多信道协作频谱感知与资源分配
Multi-Channel Cooperative Spectrum Sensing and Resource Allocation Based on Mechanism Design
多信道协作频谱感知及资源分配问题是认知无线网络中的研究热点问题。受到机制设计理论的影响,本文提出一种基于感知时间补偿机制的方法解决该问题。认知用户在不同信道上的感知时间可以补偿给认知用户将接入的信道,降低了其它认知用户的自私行为造成的影响。首先,根据信道条件将信道分类并公布不同信道间的补偿系数;然后,用户再根据获得的补偿系数矩阵自由分配各自的感知时间;最终,频谱管理者将根据用户的实际感知时间将可用信道进行分配。实验结果证明了本文所提出的方法的可行性和有效性。
he problem of multi-channel cooperative spectrum sensing and resource allocation is a hot issue in Cognitive Radio Networks. Motivated by mechanism design theory, a method based on sensing time compensation mechanism is proposed in this paper for solving this problem. The sensing time on different channels of a Secondary User can be compensated for the channel the user will access, this method can reduce the impact of other users' selfish actions. First, the channels are divided and labeled with different compensation factor; then, users will allocate their sensing time of different channels based on the compensation factor matrix; in the end, spectrum administrator will allocate the access time of different users based on their sensing time. The simulation results shows that the proposed method's feasibility and efficiency.
