Abstract

Advanced sensory systems are the driving force behind autonomous vehicles. They have led to such vehicles producing and processing much more content-intensive visual data. It is foreseen that traffic consisting solely of autonomous vehicles will enable people and goods to travel more safely. Using millimetre wave (mmWave) frequencies for wireless communication between vehicles is a rising research topic, both to enhance safety and reliability of autonomous vehicles and to meet the data rate required by the content-intensive data-set produced by their advanced sensory systems. The main goal of this thesis is to make a stochastic analysis of the signal quality that can be achieved by vehicles when using mmWave frequencies for the wireless communication between them. To address this issue, the tools of stochastic geometry is used in this thesis. Firstly, stochastic geometry provides advanced mathematical properties to model the system fairly accurate and tractable. Secondly, resulting analytical model helps system designers to develop insights to understand relationships between system parameters.

The first academic contribution of this thesis is a two-fold probabilistic connectivity analysis of an autonomous vehicle fleet for a single-lane road. In other words, it stochastically models the connectivity probability of the sensory data of the head and tail vehicles of the fleet shared over intermediate fleet vehicles by using a Poisson point process and geometric probability tools. The proposed model takes into account both the threshold of the obtained Signal-to-interference-plus-noise ratio in terms of the critical distance requirements and the beam misalignment issues caused by the lateral displacement of the vehicles in the lane.

The second contribution of this thesis is a mean interference analysis for a typical receiver if the vehicles employ in-lane and closest vehicle routing schemes for a two-lane road. By comparing these two routing schemes, a strategy is proposed for different antenna beam widths and vehicle densities. Additionally, the distribution of autonomous vehicular traffic, that is modelled by the shifted Poisson point process, gains more realism by taking into account platooning-based headway distance requirements.

The third contribution of this thesis is a derivation of the coverage probability and road spectral efficiency for multi-lane vehicle-to-vehicle communications, by taking into account the blockage impact of adjacent lane vehicles and antenna-placement dependent path loss behaviour under an in-lane routing scheme. Finally, all the analytical models are verified by Monte Carlo simulations.
