The invention belongs to the field of intelligent traffic, and provides a downlink false data detection method based on a busy intersection forwarding mode. The method comprises five parts, wherein in the first part, a data downlink scheme based on a busy intersection forwarding mode under fog computing is provided; and the second part is to select a busy intersection according to the traffic demand of the intersection and the distance between the intersections. And the third part is to select candidate supervised vehicles for detecting false data according to a network topology structure generated by a data downlink scheme. And the fourth part is to calculate the reliability of the vehicle according to the historical trajectory of the candidate supervised vehicle, and select a final supervised vehicle according to the reliability of the vehicle. And the fifth part is downlink false data detection, the supervision vehicle compares data received from the fog server with data received from other vehicles, so that the authenticity of the data is judged, and the fog server is assisted in finding out malicious vehicles sending false data.
本发明属于智能交通领域,提供了一种基于繁忙交叉口转发模式的下行虚假数据检测方法。该方法包括五个部分,第一部分是提出一种雾计算下基于繁忙交叉口转发模式的数据下行方案。第二部分是根据交叉口的交通需求以及交叉口之间的距离选择出繁忙交叉口。第三部分是根据数据下行方案产生的网络拓扑结构选择出用于检测虚假数据的候选监督车辆。第四部分是根据候选监督车辆的历史轨迹计算车辆可靠性,并根据车辆可靠性选择出最终的监督车辆。第五部分是下行虚假数据检测,监督车辆将从雾服务器处接收到的数据与从其他车辆处接收到的数据进行对比,从而判断数据的真实性,并协助雾服务器找出发送虚假数据的恶意车辆。
