Virtual Cognitive MAC for Visible Light Communication System

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 environm...

Visible Light Communication

The visible light communication (VLC) refers to the communication technology which utilizes the visible light source as a signal transmitter, the air as a transmission medium, and the appropriate photodiode as a signal receiving component. The visible light communication technology has a short history compared with other communication technology, for example, public old telephone service, Ether...
