The invention discloses a prediction-based routing method at an intersection in a vehicle self-organizing network, and mainly solves the problem that when a packet is routed at the intersection, a link is unstable in the prior art. The scheme for implementing the method is that: when the packet arrives at a previous hop node of the intersection, the node predicts the next intersection to which the packet is transmitted; a weight of each adjacent intersection is calculated according to the density of adjacent road sections and a distance from the next intersection to a destination, and the intersection with the largest weight is selected as the next temporary destination for transmitting the packet; and when the packet is forwarded in a greedy mode in the road section, if the selected nodeis positioned in the boundary of the transmission range and is opposite to a driving direction of the transmitting node, a node secondarily nearest to the destination is selected, otherwise the packet is directly forwarded to the selected node. Compared with the geographic routing in city scenarios (GPCR) protocol and the greedy perimeter stateless routing for wireless networks in urban vehicularscenarios (GpsrJ+ protocol), the method has the advantages that: the transmission rate of the packet is increased, the transmission time delay of the packet is reduced, and the method can be applicable to the vehicle self-organizing network.
