HARDWARE SETUP FOR VLC BASED VEHICLE TO VEHICLE COMMUNICATION UNDER FOG WEATHER CONDITION
LED based systems are being developed recently which incorporates an optical wireless communication system (OWC). Attention is being given to an OWC technology which uses visible light LEDs, also known as Visible light communication (VLC). Weather conditions such as rain, snow & fog affects optical channel causing significant transmission quality drop of a LED based Vehicle-to-Vehicle communication channel. Majorly Fog affects the VLC link causing high atmospheric attenuation. As taillights are being used as a transmitter in this setup of V2V, there is no requirement of using large number of transmitters and receivers in V2V.Hence a working hardware setup of LED based V2V for fog condition still needs to be tested. It is being done to find an alternative for RF based V2V which is an expensive method.
