Using renewable energy to power Road Side Units (RSUs) is a desirable alternative, since it lowers both the carbon footprint and the cost of deployment.Therefore, for renewable energy RSUs, two online distributed scheduling strategies are proposed in this paper to maximize the number of served vehicles.In the Markov chain-based scheduling strategy, the energy state of RSUs is expressed by Markov chain, and the number of served vehicles is maximized by rewarding action.While in the threshold-based scheduling strategy, the harvested energy in RSUs as well as the energy consumed by serving vehicle is calculated to select the number of served vehicles.Simulation results show that the proposed online scheduling strategies increase the capacity of serving vehicles.
