Cross-Layer Design on Software Defined Vehicular Network(SDVN) based on Radio Access Technology(RAT) IEEE 802.11 bd to Improve End-to-End Communication Performance

Vehicles and transportation have transformed from the field of mechanical & civil transportation field to the scientific field of information technology and electronics. This transformation is marked by the widespread use of ADAS, ITS, and Autonomous Vehicles on the Internet of Vehicles (IoV) in the future, aiming to improve safety and operational transportation efficiency, which will encourage the use of vehicular communication technology on a large scale.The complexity of the vehicular communication system raises many problems, which in turn encourages the emergence of various studies to solve these problems. One problem that arises is the blocking problem in vehicular communication based on 802.11bd Wifi in areas with high vehicle density. In previous studies, this problem was tried to solved using the Cross-Layer Design Based Transmit Antenna Selection (TAS) and Transmit Power adaptation (TPA) approach at the PHY & MAC layers.However, two problems later arise in the solution applied: the additional latency due to communication between nodes for coordination purposes. The study conducted is still limited to single-hop conditions.
