Due to their capacity to permit communication between automobiles and infrastructure components, Vehicular Ad-Hoc Networks (V ANETs) are growing in popularity. Intelligent transportation systems (ITS) have seen the emergence of Vehicular Ad-Hoc Networks (V ANETs) as a promising technology, but effective data distribution is still a problem. Conventional methods of data sharing require a lot of energy and are inappropriate for V ANETs with limited resources. The efficient transmission of data between vehicles, which consumes a lot of energy, is one of the major difficulties in V ANETs. We suggest a cross -layer design strategy in this study to incr ease the energy efficiency of data distribution in V ANETs. To maximize network performance, the design incorporates the capabilities of many layers of the protocol stack. We implement several energy -saving techniques, such as cooperative communication, pow er control, priority -based message scheduling, and sleep mode. The simulation findings demonstrate that the suggested design strategy can greatly lower energy usage and enhance V ANETs' sustainability.
