Performances Evaluation Study of VANET Communication Technologies for Smart and Autonomous Vehicles

The amazing advanced in high technologies allows Intelligent Transportation Systems (ITS) to become an integral part of our daily life. Smart and autonomous vehicles illustrate these new transportation structures. The interaction and communication between vehicles in such systems are considered the key elements and illustrated by the different V2X (Vehicles to Vehicle and Vehicle to Infrastructure) technologies proposed in the market place. The Vehicular ad-hoc networks(VANETs) and LPWA technologies as the fifth generation mobile communication(5G) and IEEE 802.11p protocol could be a proper solution. In this paper, the architecture of these standards were analysed. The key parameters of IEEE 802.11p were implemented in Veins Framework combined with Omnet++ network simulator and SUMO Mobility simulator, to accurately simulate VANETs. The performance of this standard was measured in Veins Framework using realistic vehicular mobility models. Then, the main performance metrics; Timeliness, Throughput and Packet Loss Ratio were analyzed when varying the different messages sizes in the scenario. and Then a rebroadcasting process was analysed when varying the number of nodes.
