Abstract
Vehicular communications (VC) have been proved to provide useful contributions in the context of accident prevention thanks to the transmission of alert messages. This is even truer at road intersections since these areas exhibit higher collision risks. In this paper, we study VC at road intersections, considering non-orthogonal multiple access (NOMA) in the presence of interference, when two destination nodes are involved. First, we calculate the outage probability for each destination node. Then we calculate the outage probability when the destination nodes are either on the road (vehicle, cyclist, pedestrian) or outside the road (base station, road side unit). Closed forms are obtained for specific values of the path loss exponent. We compare the performance of NOMA with orthogonal multiple access (OMA) and we show that NOMA has a better performance than OMA. We also compare NOMA performance in two different scenarios, road intersections and highways, and show that the outage probability is higher in the first scenario.
