道路上越来越多的自动驾驶和半自动驾驶车辆导致对外部车辆通信的需求不断增加，特别是通过新兴的车辆自组织网络（也称为vanet）。这项技术能够促进智能交通应用、舒适性和自动驾驶汽车所需的其他服务。然而，为了在自动驾驶汽车中提供稳定的路由并实现高性能的外部通信，需要使用合适的路由协议。自组织按需距离矢量路由（AODV）迄今为止很少在移动自组织网络中使用，但作为一种响应路由协议具有很大的潜力。然而，当AODV协议直接应用于VANETs时，会受到性能差的影响。本文对AODV的路由选择和路由发现进行了两方面的改进，以提高其在vanet中的分组传输速率和通信链路稳定性。因此，我们获得了适合自动驾驶汽车通信特定要求的新型车辆V-AODV。仿真结果表明，V-AODV可以增强路径稳定性，降低开销，改善车辆间通信性能。
The increasing number of autonomous and semi-autonomous vehicles on the road leads to an increasing need for external vehicle communication, in particular through emerging vehicular ad hoc networks also known as VANETs. This technology has the ability to facilitate intelligent transportation applications, comfort and other required services for self-driving vehicles. However, suitable routing protocols need to be utilised in order to provide stable routing and enable high performance for this external communication in autonomous vehicles. Ad hoc on Demand Distance Vector routing (AODV) is to date rarely used in mobile ad hoc network but offers great potential as a reactive routing protocol. However, the AODV protocol is affected by poor performance, when directly employed in VANETs. In this paper, two improvements are presented to the route selection and route discovery of AODV to improve its performance in forms of packet delivery rate and communication link stability for VANETs. Thus, we obtain new vehicle V-AODV that suits the specific requirements of autonomous vehicles communications. Simulation results demonstrate that V-AODV can enhance the route stability, reduce overhead and improve communication performance between vehicles.
