Embodiment 1
[0054] This embodiment provides a vehicle-mounted ad hoc network routing decision-making method in a hybrid network mode. The vehicle-mounted ad hoc network includes traffic road structures, vehicles, and RSUs (road side units). Multiple RSUs are deployed in the traffic road structure, and multiple RSUs Two-two communication connection, the routing decision-making method includes the following steps:
[0055] 1) Abstract the traffic road structure into a directed graph composed of directed edges and intersections;
[0056] 2) Obtain vehicle driving data in the traffic road structure in real time, abstract each vehicle into a directed vehicle node in a directed graph according to the vehicle driving data, and construct a vehicle node mobile behavior model;
[0057] 3) Obtain two vehicles that need to communicate as the starting node and the destination node;
[0058] 4) Based on the communication range of each node, obtain candidate nodes from the directed graph, select accord...
