摘    要:针对车辆移动速度快、行驶路径受道路约束、网络拓扑结构易改变的特点,提出了一种基于流行病模型的车路协同安全预警信息交互方法,并采用马尔可夫链对传播延迟进行了理论分析.实验采用NS2网络仿真平台,构建了2 000 m长、20 m宽的双向车道测试场景,移动节点间采用802.11协议,实验测得的延迟结果与理论分析基本一致.

关 键 词:车路协同  交通安全  流行病模型  马尔可夫链

Abstract:Based on the characteristics of high speed,the movement was constrained by roads,and the vehicle networking topology changed frequently,a cooperative traffic safety alarming method based on epidemic model was presented,and the transmitting delay was analyzed with Markov chain.The method was tested with NS2 network simulator.The simulation scenario contains a 2 000 meters long and 20 meters wide highway,which allows two-way movements of vehicles.The experimental results prove that the transmitting delay is c...
Keywords:vehicle infrastructure integration  traffic safety  epidemic model  Markov chain
