2.9 Future Enhancement and Research Directions
ОглавлениеThe technological infrastructure such as vehicles to everything and vehicle to infrastructure communications modes can be enhanced.
The Intelligent Transportation System (ITS) performance can be enhanced.
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.
