摘要:
随着车联网的快速发展,交通信息的传输需求也随之增长。 然而在当前的车联网信息传输系统中,不仅因为物理距离过长、传输流程复杂而容易造成丢包、传输过慢和网络 堵塞的问题,而且用户进行的信息操作工作流程也比较繁琐,不利于车联网的信息传输系统的发展。 为此,针对车联网交通信息传输,引入移动边缘计算技术(mobile edge computing, MEC),提出面向车联网的高效点对点信息传输机制。 首先,优化交通传输系统场景,在其网络信号基站中引入 MEC 服务器,并分析在其传输系统中加入 MEC 服务器后的传输特点并设计出对应的点对点传输系统。 然后,为同时满足车与车和车与路之间的信息传输,分别编写用户设备间数据传输子系统和数据传输辅助服务子系统。 编写完成后对标之前分析的传输特点进行优化,设计并实现了系统优化的关键技术。 实验结果显示,新机制可显著降低服务响应时延,提升车联网信息传输效率
Abstract:
With the rapid development of Internet of vehicles,the demand of traffic information transmission is also increasing. However,in the current information transmission system of Internet of vehicles,it is not only easy to cause packet loss, slow transmission andnetwork congestion due to the long physical distance and complex transmission process,but also tedious information operation workflow for users,which is not conducive to the development of information transmission system of Internet of vehicles. For this reason,aiming tothe traffic information transmission of the Internet of vehicles,the mobile edge computing (MEC) is introduced and an efficient point-to-point information transmission mechanism for Internet of vehicles is proposed. First,the traffic transmission system scenario is optimized and MEC server is introduced into its structure. Then,the transmission characteristics of MEC server are analyzed and the corresponding point-to-point transmission system is designed. In order to satisfy both vehicle-to-vehicle and vehicle-to-road direct information trans鄄mission,the data transmission subsystem and the data transmission auxiliary service subsystem are respectively written. After the preparation, the transmission characteristics of the analysis before the standard are optimized, and the transmission optimization technology for system optimization is designed and realized. The experiment shows that the new mechanism can significantly reduce the service response delay and improve the efficiency of vehicle Internet information transmission.
