Layout optimization method of short-range communication system roadside communication unit special for Internet of vehicles

The invention discloses a layout optimization method of a short-range communication system roadside communication unit special for the Internet of vehicles. The method includes the steps that firstly, an Internet-of-vehicles roadside unit network in an actual application scene is extracted and abstracted into a complex network; secondly, a target function and an efficiency and cost function are built; thirdly, initial disturbance is introduced to simulate the cascading failure process of the network, and parameters of the target function are adjusted; fourthly, parameters in the CRO algorithm are determined, and the iteration process is executed to obtain the global optimal solution; fifthly, change trends of four theoretical index values corresponding to the global iteration process are recorded and saved in an information database, and qualitative and quantitative evaluation and reference are provided for similar network optimization. The network structure of the Internet-of-vehicles roadside unit network i
