An infrastructure-free Internet of Vehicles connectivity research and judgment method

The invention discloses an infrastructure-free Internet of Vehicles connectivity research and judgment method. In the Internet of Vehicles with infrastructure, the interconnection of the whole networkcan be ensured due to the existence of the RSU, but the communication between vehicles completely depends on the own interconnection of the vehicles under the condition of no infrastructure, and as the vehicles are unevenly distributed in the road network, the possibility that the whole network is not communicated greatly exists. The invention aims to solve the problems, by defining and analyzingproperties of vehicle nodes in the road network without the infrastructure, the connectivity condition and the judgment method are provided, so that the purpose of evaluating the connectivity of theinfrastructure-free Internet of Vehicles (VANET) is achieved, a foundation is provided for the connectivity prediction and the connectivity of the infrastructure-free Internet of Vehicles, and the method has important significa
