Embodiment Construction
[0014] The present invention takes a certain business district in Chongqing as the research object, which includes squares, pedestrian streets, bus stations, etc., and is representative to a certain extent. First of all, we selected 140 points on the main arterial road. The selection principle is to lay RSU at intersections and important business circles as much as possible under the premise of ensuring that the area is completely radiated by RSU, and the laying density of different locations is also the same. Be the same and label it.
[0015] The original model can be simplified as the covering problem of finding the minimum point by genetic algorithm according to the weight. Model establishment: The node coverage area is generally regarded as a circle. In this model, the roadside unit is a node, assuming that its perception radius is R, d(i m , j n ) represents the roadside unit i m with RSU j n distance, for point i 1 , if for all other points j n (n∈V), where V repr...
