This paper proposed a genetic algorithm to reduce the dead zone of indoor visible light communication by optimizing lamps distribution. There are some rooms in different states are taken into account in this paper, including the fraises or windows in the room. Besides that, the lighting requirement of the room is also influencing the lighting source layout. By the efforts of genetic algorithm, the effective area ratio can achieve 97.28% in an empty room, or 91.04% in the room with ambient light noise. In the room with fraises, the effective area ratio is between 94.85% to 95.71%. It can be demonstrated by experiments that the genetic algorithm can meet the requirement of optimized the lighting infrastructure design in a dynamic environment.
This paper proposed a model of traffic control system which used the technology of visible light communication. By using some simulation software like Python or MATLAB, the optimized parameters can be found. For example, the best angle of the traffic light is 8.76 degree, the minimum and maximum distance of the light can received are 4.46 and 97.25 meters in this system respectively. With these parameters, we can also simulate the distribution of incident power on the road, including the crossing road or the roundabouts. As a result, incident power always centralizes on the center of the road. Eventually, some solutions are found to deal with these problems.
