Quality of Experience is one of the core structures of the transport system. With the aid of emerging of the Fifth Generation (5G) Mobile Communication Systems and software well-defined networks, the recital of Vehicular Networks could be heightened and fresh applications of vehicular networks obligatory by upcoming vehicles can also be realized such as video sharing of road condition through internet, watching the speed and position of vehicles, applications like infotainment and so on. In order to encounter the requirements of intelligent transportation systems, new vehicular network architecture shared with 5G mobile communication technologies, software defined network and Internet of Vehicles is proposed in this paper. Moreover, Internet of Vehicles based fog cells have been projected for dispensing the complex processing of cloud data center down to the edge of the network. This permits the flexibly in covering vehicles and avoids regularly delivery between vehicles and Road Side Units (RSUs). Based on the wished-for 5G software definite vehicular networks, the transmission deferral and throughput are analyzed and likened. Replication results specify that there happens a smallest transmission delay of 5G software well-defined vehicular networks considering diverse vehicle densities. Moreover, the throughput of fog cells in 5G software clear vehicular networks is healthier than the quantity of traditional transportation management systems.
