摘要
恶意信息感染网联车队后,会对跟驰行为产生影响,降低道路利用率或危害车队安全,需要研究恶意信息的感染过程并提出解决策略。基于独立级联模型提出了恶意信息与免疫信息的双向传播模式,根据通信传输差异建立了双层信息传播模型,参考补丁治愈网络病毒的免疫机制提出了观察者车辆治愈车队的方法。以信息功能为分类依据将传播信息分为目标信息、恶意信息和免疫信息,以传播模式差异为依据将传播信息置于相应模型层面。在搭建的仿真平台中,模拟网联车队的跟驰控制场景,通过注入恶意信息以验证所提出双层信息传播模型的可行性,提出愈速比概念作为试验变量,并讨论观察者车辆在网联车队中的最佳设置参数。结果表明:双层信息传播模型能够合理阐释网联车队恶意/免疫信息的传播机理,目标信息定向传输给所需车辆,恶意信息与免疫信息在通信交互层双向传播,实现相应的感染或治愈功能;当免疫信息的治愈时间固定时,观察者车辆的最佳位置是车队中段,可实现车队平均车间距偏差最小;当观察者车辆在车队中段位置时,愈速比存在设置最优值,可同时兼顾治愈成本与治愈效果;提出的观察者车辆策略能够有效抵御恶意信息传播带来的危害。
After the malicious information infects the connected vehicle platoon,it would have an impact on the car following behavior,and reduce the road utilization rate or endanger the safety of vehicle platoon.It is necessary to study the infection process of malicious information,and to propose solutions.A bidirectional propagation mode of malicious information and immune information is proposed based on the independent cascade model.A double-layer information propagation model is established based on communication transmission differences.A method for observer vehicle healing platoon is proposed referring to the immune mechanism of patch healing network viruses.According to the information function,the propagated information is classified into target information,malicious information,and immune information.According to the propagation pattern differences,the information is placed in the corresponding model layer.In the constructed simulation platform,the platooning control scenario of connected vehicle platoon is simulated.By injecting malicious information,the feasibility of proposed double-layer propagation model is verified.The concept of healing speed ratio is introduced as an experimental variable,and the optimal setting parameters for observer vehicles in the connected vehicle platoon are discussed.The result indicates that the double-layer propagation model can reasonably explain the propagation mechanism of malicious information and immune information in the connected vehicle platoon.The target information is direct transmitted to the required vehicles.The malicious and immune information bidirectionally propagated in the communication interaction layer to achieve the respective infection or healing functions.When the healing time of immune information is fixed,the optimal position for observer vehicles is in the middle of platoon,which could achieve the smallest average vehicle spacing deviation.When the observer vehicle is positioned in the middle of platoon,there is an optimal value for the healing speed ra
