1. Introduction of Internet Access of Vehicular Networks

Connected vehicles are changing the modern transportation. Based on the wireless communication between vehicles with sophisticated radio interfaces, vehicles in the mobility world can exchange information with neighbors as well as remote transportation center, which can enable the vehicle to understand both the in-vehicle status and the road situation. Based on such capability, a lot of smart road applications can be realized, including the safety-related application, intelligent transportation system (ITS) and in-vehicle infotainment, etc. The Internet access for vehicles can further extend the spatial scope and temporal range of the vehicular communication, which can help all road users to conduct both the long-term evaluation and short-time response to all situations. In this chapter, we first introduce the overview of Internet of vehicles (IoV), then we present the Internet access procedure for a vehicle to connect to a wireless access station that deployed along the roadside. We then explain the aim of the book, covering the topic of Internet access performance evaluation, data traffic offloading, Internet link management and intelligent machine learning (ML) paradigm over IoV.
