Performance of Vehicular Comminications

Baha Eddine Youcef Belmekki

Autonomous and connected vehicles, whether for personal transport or freight delivery, could offer a potentially enormous disruption to life, business, and society, and are expected to be pervasive in society in the near future. They Will reduce the rate of accidents arising from human error, reduce cost & environmental impact of transport, liberate time currently committed to driving. In order to make proper decisions and being able to self-drive, autonomous vehicles need to be aware of their surrendering. To that end, vehicles communicate between themselves and share status information, such as status brakes, speed, and heading directions, but they also communicate with infrastructure to be aware of the environment, such as traffic jams or accidents. This highlights the importance to ensure reliable vehicular communications by first elevating, then improve them.

To improve these type of communications three aspects will be explored, increasing the diversity by cooperating, increasing the spectral efficiency by implementing the Non-Orthogonal Multiple Access (NOMA) scheme, and increasing the backhaul coverage by using Networked Flying Tethered Platforms (NTFSs). Indeed, vehicles need to cooperate to achieve a given task, for instance, vehicles can cooperate to relay a
communication when the line-of-sight communication is obstructed between the transmitting and the receiving vehicle. Also, implementing NOMA in vehicular communications can allow several vehicles to be served using the same resources (e.g., time and frequency). Finally, using NTFPs can significantly increase the mobile coverage and the backhaul capacity.
