Toward Electrical Vehicular Ad Hoc Networks: E-VANET

The oil consumption and CO2 generation were the drives to innovate electric vehicles. At the recent years, there is large evolution in the industry of electric vehicles and in the near future, the normal vehicles may be replaced with electric vehicles. The energy consumption of these vehicles depends on the vehicle body size and weight, passengers' weight, mobility speed, and vehicle communications. In this paper, we focus only on vehicle communications and propose a new concept called Electrical Vehicular Ad Hoc Network (E-VANET). E-VANET is a new trend of vehicular ad hoc networks (VANET) which composes of connecting a group of electric vehicles with each other and with the infrastructure to exchange information. In addition to the challenges of VANET such as mobility, routing, location awareness, etc., the main challenge in E-VANET is energy consumption that needs a great research effort to be reduced. Therefore, it is necessary to highlight E-VANET and new concepts, standards, and technologies that can be used to enhance its performance and reduce energy consumption. The main goal of this paper is to explain the concept of this new network type, its architectures, applications, and challenges as well as the technologies that can be merged with it to increase the network lifetime like software-defined network, fog computing, internet of vehicles (IoV) and cloud computing. This paper can open the door in front of the researchers to contribute in enhancing the work of E-VANET.
