An urban scene in a car infrastructure networking connectivity model deduction method

Kind of urban scene in a car infrastructure networking connectivity model deduction method. The present invention defines a route backbone: a plurality of intersection gateway i, i, ..., i composition, these road junctions gateway group r, r, ..., r adjacent, where n = m-1. Obtaining by each of the trunk road network on a road and the vehicle speed all the vehicle is equipped with on-line transmission range of the wireless communication device and vehicle density statistics on those roads, four attributes of connectivity route backbone modeling . The present invention is directed to the urban scene vehicle networking objective there are four low coupling interconnection, problems such as differences in the application needs to study the composition of the trunk road network messages via a gateway city roads and junctions spread, forming a network interconnection when the car the nature of communication, according to the nature of the proposed urban scene in a car infrastructure networking connectivity model, this car networking development of large-scale network applications have important theoretical significance.
