Emerging technologies and research challenges for intelligent transportation systems: 5G, HetNets, and SDN

Abstract

With the rapid advance of the intelligent transportation system (ITS), the vehicular networks have a potential importance. Currently, these networks are suffering a major challenge due to the widespread demand for services associated with shipping safer, more efficient, cheaper, infotainment, and more sustainable. Researchers and companies are working to generate novel applications. Intelligent Transportation Systems that aim to reorganize the operation of vehicles. With the need for technological convergence in communications, it is necessary to refer of vehicular heterogeneous, autonomous, flexible and programmable networks. New emerging technologies open up interesting gaps for research and development of future networks. In this paper, we present an overview on wireless technologies and potential challenges to provide vehicle-to-x connectivity; such as the connected vehicles or self-driving cars, that will be the first robots that have a direct effect on the daily lives of millions of people. Particularly, we examine the 5G architecture designed with Software Defined Networking and their role in Heterogeneous Networks.
