Vehicle-mounted communication routing method

The invention discloses a vehicle-mounted communication routing method, which can fully meet the characteristics of high mobility of vehicle network nodes and quick topological structure change. Eachnetwork node obtains the geographic position information of the network node, the adjacent node and the target node through the satellite navigation system, and when the nodes forward data, the nodesdo not need to know the state information of the nodes except the target node and the adjacent node, so that the cost of maintaining the information is reduced. A node is subjected to movement detection; when a node is selected for data forwarding, packet loss phenomena can be reduced, the reliability of node communications is improved; through a linear jump strategy and an included angle selection strategy, the routing protocol provided by the invention can meet the requirements of various occasions; the routing hop count of a specific scene is reduced, the end-to-end time delay is reduced, and for the problem of fall
