New anti-worm model in vehicular internet of things based on divide-and-conquer with velocity

To prevent and cure vehicular Internet of things(IOT)worm,according to the property of resisting potential worm attack in vehicular IOT different from traditional networks,a new anti-worm model in vehicular IOT is constructed based on divide-and-conquer with velocity.The paper treats the drive velocity of vehicle node as the conversion condition between active and passive anti-worms in hybrid anti-worms,constructs a new model combining with the environment of vehicular IOT in urban road,and implements the simulation of vehicular IOT anti-worm.The model can not only better contain the vehicular IOT worm propagation,but also better hold down the network resource spending in anti-worm.
