Abstract
This paper considers the multiple RSUs scheduling problem for energy efficiency in sparse VANETs. For improving the RSUs’ energy efficiency, an RSU can perform ON–OFF conversion when there is no vehicle data transmission requirements in the transmission radius of it. And we formulate the multiple RSUs’ scheduling problem as an integer non-linear programming issue which is NP-hard with a high complexity. Then we propose three locally optimum algorithms called Nearest Fastest (NF), Integrate Deadline and Remaining Requirements (IDRR) and NF-IDRR to give a sub-optimal approximation of this problem. In the three locally optimum algorithms, we consider both RSUs’ energy consumption and vehicles’ requirements. Simulation results show that the three algorithms can improve RSUs’ energy efficiency. Furthermore, in the three locally optimum algorithms, NF-IDRR has lower energy consumption and higher vehicles requirement completion rate than other two.
