- Abstract
- This paper presents the simulation result of comparing two transmission methods which are to send VLC messages to lighting fixtures based on DMX over IP and evaluates the successful receipt rate for VLC Message Broadcast System (VMBS) which has the features of transmitting not only the LED-ID (positioning-ID) but also broadcast messages. The simulation result shows that the Multicast & Multiplexing method for LED-ID messages decrease the delay of 5.3%.The evaluation result of VMBS shows that the successful receipt rate for VLC receiver is 100% when VLC receiver is located within the beam angle of VLC-LED lighting.
