Cognitive Radio technique exploits underutilized licensed spectrums to improve its bandwidth availability. Using CR technology, node is able to adapt its transmission and reception radio parameters including channel frequency dynamically according to local spectrum availability. In visible light communication, due to the limitation and heterogeneous effect of color channel on different environment, the link quality will effect. In this article, new approach for multi-channel MAC for visible light communication, named Virtual cognitive MAC, is proposed to increase the performance of visible light communication system. It can be used in the promising communication technology, VLC, an encouraging green and energy-efficient communication technology. Numerical results show that, with the proposed system, we can reduce the blocking probability and improve the system performance.
