Abstract

This paper comes up with a SDN based On-Demand Routing Protocol, SVAO, which separates data forwarding layer and network control layer, as in SDN, to enhance the data transmission efficiency within VANETs. The Roadside Service Unit plays the role of Local Controller and is in charge of selecting vehicles to forward packet within a road segment. All the vehicles state in the road. Correspondingly, a two-level design is used. Global Level is distributed and adopts a ranked query scheme to collect vehicle information and determine the road segments along which a message should be forwarded. And the Local Level is in charge of selecting forwarding vehicles in each road segment determined by the global level. We compare SVAO with popular ad-hoc network routing protocols, including OLSR, DSR, DSDV, and DB via simulations. We consider the impact of vehicle density, speed on data transmission rate and average packet delay. The simulation results show that in case of large network scales or high vehicle speed, SVAO performs better than the others.

车载自组织网络中基于按需路由协议的软件定义网络

本文提出了一种基于SDN的按需路由协议(SVAO)，该协议将SDN中的数据转发层和网络控制层分开，以提高VANETs内部的数据传输效率。路边服务队扮演本地控制器的角色，负责选择车辆在路段内转发数据包。所有的车辆都停在路上。相应地，采用了两级设计。Global Level是分布式的，采用排序查询方案来收集车辆信息，并确定消息应该转发的路段。Local Level负责在global Level确定的每个路段中选择转发车辆。我们通过仿真将SVAO与流行的ad-hoc网络路由协议(包括OLSR、DSR、DSDV和DB)进行比较。我们考虑了车辆密度、速度对数据传输速率和平均数据包延迟的影响。仿真结果表明，在网络规模较大或车速较高的情况下，SVAO算法的性能优于其他算法。
