Abstract: In urban-road environment vehicular Internet of things vehicle nods draw over an omnirange and complex road conditions domain, the road environment has barrier, superimposed disturbance influence over wireless signal. Inosculating with the intelligent driver model, we investigated the outbreak of worm epidemics in vehicular Internet of things. Our study constructed a vehicular Internet of things worm propagation model with vital mean velocity and shadow-fading component This model preferably shows the influence over worm propagation in vehicular Internet of things by these components, and factually simulates the worm propagation in vehicular Internet of things, and provides a theoretical basis for programming real-time detection strategy and preventing worm destructive epidemics in vehicular Internet of things.

Key words: Internet of things, Vehicular networks, Network security, Worm model, Urban-road
