The invention claims an ant colony adaptive Internet of Vehicles routing selection method based on link quality. The method comprises the following steps: calculating a road connection probability, atransmission delay and a packet delivery rate, and performing comprehensive consideration to establish a link quality model; and combining the link quality with an ant colony algorithm to propose a LACOR algorithm, and adaptively searching for an optimal path in Internet of Vehicles routing for information transmission. According to the scheme, the influence of a vehicle communication radius, a road segment length, a data packet size, vehicle density and other factors in a road traffic environment on the link quality are comprehensively considered, the LACOR algorithm is proposed in combination with the ant colony algorithm to find the optimal transmission path, and finally, experimental simulation shows that there is a significant improvement in the transmission delay and packet deliveryrate compared with other methods.
