摘要：Vehicular Ad hoc Network (VANET) is a new technology that integrates the potentials of next generation wireless networks into vehicles. The design of routing protocols in VANETs is crucial in supporting the Intelligent Transportation Systems (ITS). Typical geographic routings only use local information to make routing decisions which may lead to local maximum and sparse connectivity problems. This paper proposes a novel SDN-based geographic routing (SDGR) protocol for VANET, based on node location, vehicles density and digital map. Software-Defined Networking (SDN) is used to decouple the network management from data transferring. In SDGR, the central controller gathers information of vehicles and provides a global view to compute the optimal routing paths. Simulation results show that the proposed scheme performs much better than related routing protocols in terms of both packet delivery ratio and delivery delay time.
