“…Therefore, it is called Vehicle2Vehicle (V2V) it can be used to communicate with the infrastructure as well and is then referred to as Vehicle2X (V2X) communication. Wider use in the automotive environment will lead to high market penetration [9] and availability as well as extremely low cost for the technology. Here, messages will be exchanged between vehicles using car-to-car communication (C2C) or via roadside units (RSU) using car-toinfrastructure communication (C2I).…”

Currently, there are only a few technical aids or even control methods to accelerate autonomous buses in urban traffic or to provide them with an extended green phase. This is necessary because their speed is very different from other road users. Communication between autonomous buses and the infrastructure using vehicle-to-everything (V2X) communication is already possible and well researched. It is not yet supported by many manufacturers of the control units and also manufacturers of vehicles. In the project, we have researched the development of a new traffic light signal system (LSA) control procedure with innovative traffic light system communication and detection technology and also implemented it in real traffic. The results from the research can currently already be used for small vessel sizes. The offer can be extended by possible on-demand stops and the correct reaction to vehicles with official duties like police, fire department or ambulance vehicles. In particular, interchanges without a driver present or the usual stop infrastructure at virtual on-demand stops require more passenger guidance by autonomous transport modes.

“…The second phase is the transmission of V2V links (i.e., links CHV-1→CHV-2 and CHV-2→CHV-3), where the amplifyand-forward (AF) protocol is employed by CHV-1 and CHV-2. For V2I communications where only the receivers are in motion, some theoretical analysis and experimental results demonstrate that the received signal amplitude of V2I links may follow the Rayleigh distribution [38], [39]. Note that the propagation channels of V2V communications are more dynamic than those in V2I, thus the envelope of the resulting narrowband impulse response should be modeled using the dual-Rayleigh distribution [40], [41].…”

Power Control for Clustering Car-Following V2X Communication System With Non-Orthogonal Multiple Access

et al. 2019

Vehicle clustering has been utilized for reducing the complexity of vehicle-to-everything (V2X) communications that would ultimately improve road traffic efficiency. Using a car-following model in a V2X communication system, we propose a vehicle clustering method for dynamically classifying vehicles and adjusting cluster size in real time. The especially important issue for the selected cluster-head vehicles (CHVs) can achieve an optimal trade-off between the CHVs' relative speed and power allocation. Furthermore, in order to balance the power allocation among the CHVs to further increase the downlink throughput, a power control approach for non-orthogonal multiple access (NOMA) is proposed. In this approach, the power allocation coefficients are obtained by maximizing the achievable rate while meeting the predefined target rate of each NOMA user. Finally, numerical simulations are provided to confirm the theoretical results and demonstrate the superior performance of the proposed approach. Note that through the numerical simulations, we can find the critical point of maximizing the minimum achievable rate among the CHVs at low transmission power of base station (BS).
