The rapid growth in the transportation sector has led to the emergence of smart vehicles which are equipped with information and communication technologies (ICT). These modern smart vehicles are connected to the Internet to have various services such as road condition information, infotainment, and energy management. This kind of scenario can be viewed as vehicular cyber-physical system (VCPS) where the vehicles are at physical layer and services are at cyber layer. However, network traffic management is the biggest issue in the modern VCPS scenario as the mismanagement of the network resources can degrade the quality of service (QoS) for the end users. To deal with this issue, we propose a software defined network (SDN)-enabled approach, named SeDaTiVe, which used deep learning architecture to control the incoming traffic in the network in VCPS environment. The advantage of using deep learning in network traffic control is that it learns the hidden patterns in the data packets and creates an optimal route based on the learned features. Moreover, a virtual controller based scheme for flow management using SDN in VCPS is designed for effective resource utilization for providing QoS. The simulation scenario comprising of 1000 vehicles seeking various services in the network is considered to generate the dataset using SUMO. The data obtained from the simulation study is evaluated using NS-2 which proves that the proposed scheme effectively handles the real-time incoming requests in VCPS. The results also depict the improvement in performance on various evaluation metrics like delay, throughput, packet delivery ratio, and network load by using the proposed scheme over the traditional SDN and TCP/IP protocol suite.Index Terms-Traffic control, deep learning, software-defined network, vehicular cyber-physical system. ! • A.
