A VANET based electric vehicle energy management information system

Abstract

Electric vehicles (EVs) are an integral part of the future transportation systems due to enhanced fuel and energy conversion efficiency. The success of electric vehicle technology requires an efficient charging management system that ensures their timely fueling. To support such a service, vehicular ad hoc networks can be used to implement an information system for EV energy management. For this purpose, it is essential for the electric vehicles to reliably and timely exchange information with the information/control servers using infrastructure nodes (INs) deployed at different geographical locations. As the INs may be located farther away from the vehicles, robust multi-hop packet transmissions are required. In this chapter, we present the design considerations for an information system for EV energy management. We propose a vehicle-to-infrastructure and infrastructure-to-vehicle (V2I-I2V) information transmission system that efficiently delivers packets for EV energy management services by mitigating the broadcast storm and hidden node problems. Moreover, the proposed system provides a signaling mechanism to select the shortest path for the downlink I2V transmissions, a challenging task due to the mobile nature of vehicles. Simulation results show that the developed system offers a low delay and reduced number of packet transmissions for different vehicle densities and mobility conditions.
