摘　　要：鉴于城市路网环境中车载物联网车辆节点在全方向复杂路况下行驶以及道路环境对无线信号存在阻挡、叠加干扰等影响,结合智能行驶模型IDM,针对车载物联网蠕虫的传播进行分析研究,构建了车载物联网蠕虫传播模型VIOTWPM。通过仿真实验证明,VIOTWPM较好地显示了车辆节点平均速度、阴影衰落等交通流量、无线信道因素对蠕虫传播的影响,为真实地模拟城市路网环境车载物联网蠕虫的传播,以及设计实时检测策略来防治城市路网环境车载物联网蠕虫的破坏性传播提供了理论基础。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 sha- dow-fading component. This model preferably shows the influence over worm propagation in vehicular Intemet 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.
