Efficient Scheduling for VANET Considering Renewable Energy

Abstract

The realization of intelligent transportation systems requires the use of specific networks such as Vehicular Ad Hoc Networks (VANETs). VANETs are used to connect vehicles with each other and with fixed infrastructure Road Side Units (RSUs). In powering the RSUs, renewable energy is a great alternative to conventional electric grid. This paper proposes an efficient scheduling algorithm for serving vehicles in a green vehicular network with the aim to maximize the number of served vehicles while maintaining a sustainable energy level. We define and compute four metrics, for each vehicle, of a substantial impact on both the quality of service (QoS) and the power to be consumed. The proposed scheme outperforms other scheduler in terms of the percentage of served vehicles under different arrival rates, various values of average vehicle velocities, variable data size and varying the amount of harvested energy.
