面向实时感知的车联网业务监控应用研究

基于车联网的数据实时采集和人车交互的基础是可靠的网络接入服务和良好的通信保证,为此文中研究了车联网中车辆接入车联网的通信可靠性保证策略和网络质量优化方法。首先,由于车辆节点的通信不稳定性和动态性,研究了动态的车联网网络质量评估方案。其次,这项工作研究了基于车辆轨迹的对车辆接入网络的数据交互时间预测算法,以应对车联网不稳定的网络拓扑和高断开率。最后,提出了一种实时通信质量感知的网络接入策略,用于为道路上的车辆提供车联网服务。仿真结果证明了该方案在不同的通信距离下具有相对较高的网络接入成功率和较好的通信质量。

Research on real-time perception oriented vehicle networking business monitoring application

Based on the Internet of Vehicles,real-time data collection and human-car interaction are based on reliable network access services and good communication guarantee.For this reason,this paper studies the communication reliability assurance strategy and network quality optimization of vehicle access vehicle networking in the Internet of Vehicles method.Firstly,due to the communication instability and dynamics of vehicle nodes,a dynamic vehicle network quality assessment scheme is studied.Secondly,the data interaction time prediction algorithm for vehicle access network is studied based on vehicle trajectory to cope with the unstable network topology and high disconnection rate of the vehicle network.Finally,a real-time communication quality-aware network access strategy is proposed to provide vehicle networking services for vehicles on the road.The simulation results show that the scheme has relatively high network access success rate and good communication quality under different communication distances.
