【摘要】 为了评估车联网无线链路传输数据业务的能力,提出结合车辆运动模式和数据业务传输特点的车联网链路传输性能评估模型.通过蒙特卡洛仿真统计得到链路剩余生命时间分布和数据业务传输时间分布,利用分布解析推导车联网链路成功传输概率,并建立链路传输性能评估模型.在基于Matlab/Simulink的TrueTime工具箱搭建的仿真平台上,使用模型评估常用Ad Hoc路由协议基于距离矢量自组织和基于路由预测所建路径的传输性能.实验结果显示,链路性能模型能有效评估不同路由协议建立链路在不同移动速度下传输数据业务的能力.更多还原

【Abstract】 To evaluate the transmission capacity of Vehicular Ad-Hoc Networks(VANETs) wireless link,a link transmission performance evaluation model used for vehicle mobility and data transmission character is proposed.VANETs link transmission capacity metric is built based on link residual lifetime distribution and data transmission service time distribution obtained by Monte Carlo simulation and data fitting.The evaluation model is applied in VANETs simulation to assess the transmission performance of paths selected byad hoc on demand distance vector(AODV) protocol or prediction based on routing(PBR) protocol.Simulation is carried out on TrueTime tool box of Matlab/Simlink and is shown that the link transmission performance evaluation model is able to assess link transmission capacity effectively for both route protocols and different node speed scenes in data transfer service.更多还原
