车辆网联环境下的交通感知路由协议综述

A Review of Traffic Aware Routing Protocols for Vehicle Networks

智能网联车辆的快速发展使车辆与车辆、路侧设备或行人间的实时、可靠通信(V2X通信)成为可能,为使车辆网联环境下的通信路由协议更加可靠和高效,提出了一种在地理路由协议基础上融合交通状态信息的路由协议——交通感知路由协议。总结了目前车辆网联环境下的路由协议,对现有交通感知路由协议进行分类,介绍并比较了目前比较典型的交通感知路由协议,探讨了交通感知路由协议主要面临的问题和未来的研究方向。

The rapid development of intelligent networked vehicles enables the real-time and reliable communications （V2X communication） between vehicles, roadside equipment and pedestrians＇ smartphones. To generate more reliable and efficient routing protocols in the VANETs （Vehicular Ad-hoc Networks）, some scholars proposed a routing protocol called traffic aware routing which includes traffic information based on the geographic routing protocol. The paper firstly summarizes the routing protocols used in the VANETs. Then the existing traffic-aware routing protocols are classified and the typical traffic- aware routing protocols are introduced and compared. Finally the main problems of using the traffic-aware routing protocols and future research directions are discussed.
