一种优化的基于软件定义车联网的路由方法
An Optimized Routing Protocol Based on Software Defined Vehicular Ad-hoc Network
摘要
Abstract
VANET ( Vehicular Ad-hoc NETwork) plays an important role in improvement of traffic safety,enhancement of traffic effi-ciency 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 topolo-gy repairing. For this,the IEEE,which has set up a special working group,has come up with IEEE 1609 together with IEEE 802. 11p pro-tocols. But since they lack of good robustness,there exist several problem such as broadcast storm,routing failure and so on. SDN ( Soft-ware-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.关键词
