摘要
针对车载网(V2X)的异构特性,提出基于蜂窝和802.11p协议的V2X通信安全行驶模型(Cellular and 802.11p based V2X safe navigation model,CSNM).通过CSNM模型分析异构V2X各类场景的特性,从而推导各类场景的警告距离.车辆通过接收包警告距离的消息,提升行驶安全.仿真结果表明,同时采用V2V和V2N模式的通信,能够提升交互安全消息的可靠性,降低传输消息的时延,减少估计警告距离的误差.
According to the heterogeneous characteristics of vehicular network(V2X),a safe navigation model(CSNM)based on Cellular and 802.11p protocol is proposed.The CSNM model firstly analyzes the characteristics of various scenarios in heterogeneous V2X,and then deduces the warning distance in various scenarios.The vehicle receives a message containing a warning distance to improve driving safety.The simulation results show that the communication of V2V and V2N modes can improve the reliability of secure message interaction,reduce the delay of transmission message,and reduce the error of the estimation of warning distance.
