基于RSU协作的V-NDN数据转发方法研究

Research on RSU-assisted data forwarding method in V-NDN

在基于命名数据网络(NDN)的车辆自组织网络(VANET)中,车辆的高移动性使得网络拓扑结构频繁变化,通信链接不稳定,最终导致数据包传输失败.针对此问题提出了一种基于路侧单元(RSU)协助的数据转发方法.该方法首先对RSUs进行区域划分,然后利用RSUs协助数据转发,有效地解决了转发过程中数据包丢失的问题.通过实验仿真与V-NDN和基于位置的数据转发路由方法进行对比,结果表明文中提出的数据转发策略有效地降低了数据传输时延,提高了数据包的成功交付率.

In Named Data Networking(NDN)-based Vehicular Ad-hoc Network(VANET),due to the high mobility of vehicle,the network topology changes frequently and the network link is unstable,which ultimately leads to the failure of data packet transmission.To address this problem,a data forwarding method based on roadside unit(RSU)assisted is proposed.This method divides RSUs into multiple different regions,and then uses RSUs to assist data forwarding,which effectively address the problem of data packet loss in the data forwarding process.Comparing the experimental simulation with V-NDN and location-based data forwarding routing methods,the results show that the data forwarding strategy proposed effectively reduces the data transmission delay and improves the successful delivery rate of data packets.
