Cloud and IoT-Based Vehicular Ad Hoc Networks

To afford proficient centralized management via software units, the Software Defined Network (SDN) can be integrated with the service discovery architecture for 5G-VANET milieu [31, 32].

The various protocols have arisen for the discovery process in the VANET milieu and they vary substantially in terms of architecture, interface styles, languages, the message form, and so on. As such, middleware is necessary to enable the discovery processes on different milieu and to create compatibility among heterogeneous discovery. In future the efficient heterogeneous middleware has to be developed.

As VANET milieu is dynamic, to higher the reliability and lower the latency, the two expertise technologies such as SDN and Network Functions Virtualization (NFV) can be used for network slicing.

Machine learning methods can be used to analyze a large amount of data by acquiring knowledge from VANET milieu and can make cognitive decisions.

The field evaluation with more real-time and practical scenarios can be carried out.

Service discovery is the most important mechanism for applications-oriented VANET milieu. In recent days, the Internet of Things-based VANET milieu has attracted the research community, which increases the interest in the service discovery mechanism. The service discovery process in the 5G-VANET milieu dynamically discovers the services according to the requirements of the vehicular user. This paper conducted a little study on the service discovery mechanism in the 5G-VANET milieu. In order to increase the bandwidth and to lower the latency in the service discovery process, the VANET makes use of 5G technologies. Initially, this chapter discusses the fundamentals and technological details of VANET, 5G, the need of integrating the VANET with 5G, and the need for service discovery in the 5G-VANET milieu. This chapter also gives the architectural model of the service discovery mechanism in the 5G-VANET milieu. Finally, this chapter discusses the advantages and disadvantages of the service discovery mechanisms using 5G technology in VANET milieu and also gives future directions for upcoming researchers.
