Simulation of information propagation for vehicles in physical communication network models

It is important to propagate information about software update to vehicle users. In this paper, we present a computer simulation of information propagation in physical communication network models to broadcast information rapidly. In this simulation we measure the rate of information propagation of vehicles per unit-time in physical communication network models. The characteristic obtained by the simulation is as follows; a) the vehicle operation rate has a large influence on the rapidity of information propagation, b) the vehicle mobility rate and c) the vehicle density rate has influence on the rapidity of information propagation of vehicle to vehicle communication network model, d) in the information environment of vehicles of urban area, the complex communication network model can propagate information rapidly. And we grasped the communication network models to propagate information rapidly.
