摘要:
车联网在改善道路安全、提升出行效率、为乘客提供便利等方面发挥着重要作用。 由于车辆的高速移动性、网络拓扑动态变化、链路频繁变动等特征,车联网性能受限于频繁中断的路由以及路由修复带来的高开销。 为此,电气与电子工程师协会(IEEE)成立了专门的工作组,提出专用于车联网的 IEEE 1609 和 IEEE 802.11p (WAVE)协议族。 然而由于缺
乏良好的鲁棒性,该协议族存在广播风暴或者路由中断问题。软件定义网络具备较好的灵活性和可编程能力,文中结合IEEE 802.11p 和 4G 蜂窝网络,提出了一种基于 SDN 的异构车联网架构,并引入新的路由解决方案,致力于实现高数据包交换率和低延迟。 仿真结果表明,基于软件定义车联网的路由协议展示了更好的网络鲁棒性和路由可达性。
Abstract:
VANET (Vehicular Ad-hoc NETwork) plays an important role in improvement of traffic safety,enhancement of traffic efficiency and providing convenience for passengers. However,due to vehicles’ high-speed mobility,dynamic change of network topology and frequent change of link,the performance of VANET is limited by topology with frequent disruptions and high cost because of topology repairing. For this,the IEEE,which has set up a special working group,has come up with IEEE 1609 together with IEEE 802. 11p protocols. But since they lack of good robustness,there exist several problem such as broadcast storm,routing failure and so on. SDN (Software Defined Network) possesses better flexibility and programmable capacity. In combination with IEEE802. 11p and 4G network,a heterogeneous VANET architecture based on SDN is proposed,and a new routing solution is introduced,leading to high packet exchange rate and low delay. According to the simulation,the protocol proposed has greater network robustness and routing accessibility.
