摘要
针对智能交通系统遭受拒绝服务攻击的情况,将该系统当作多因系统进行处理并设计一种预测云控制方案。鉴于智能交通系统中存在规模庞大的问题,在云控制框架下对该多因系统进行整体控制设计。引入信噪比作为通信性能指标,在对网络层进行建模时考虑拒绝服务攻击产生的丢包率。针对在网络层遭到拒绝服务攻击时会出现通信质量下降的问题,采用预测云控制方案,并证明智能交通系统闭环稳定性。最后,通过仿真验证了所提算法的有效性。
In this paper,a multi-cause system is employed to model the intelligent transportation system subject to the denial of service(DoS)attack,and a predictive cloud control scheme is designed in this case.For the large-scale problems existing in the intelligent transportation system,the overall control design of the multi-cause system is carried out in a cloud control framework.By introducing the signal-to-noise ratio as the communication performance index,the packet loss rate caused by the denial of service attack is considered when modeling the network layer.Considering the problem of communication quality degradation when the network layer is attacked by the denial of service,the predictive cloud control scheme is developed and the closed-loop stability of the intelligent transportation system is proved.Finally,the effectiveness of the proposed algorithm is verified by simulation.
