In this study, a green vehicular ad‐hoc network (VANET) infrastructure is suggested. The main players in such an infrastructure are the road side units (RSUs) which are able to harvest the energy needed for their work from the surrounding environment, especially the solar energy. Such a suggestion permits to install the RSUs in any place without considering the power supply availability and hence, an extensive area is covered by the VANET infrastructure with an improved performance. To achieve this goal, a new distributed power management scheme called duty cycle estimation‐event driven duty cycling is suggested and installed locally in the RSUs in order to decrease their power consumption and to extend the lifetime of their batteries. Embedded UBICOM IP2022 network processer platform is adopted to implement the proposed RSU and the detailed design steps are described, while the necessary values of the system components such as the number of solar cell panels, battery cells capacity and so on, are tuned to suit the design goals. The suggested method is compared with other duty cycling methods to show its effectiveness to build a green VANET infrastructure.
