Performance Analysis for High-Velocity Connected Vehicles

In this paper, we analyze the performance of high-velocity connected vehicles network. We assess the V2V (vehicle-to-vehicle) architecture in two different scenarios. The first scenario involves direct communication between source and the destination via a non-line-of-sight (NLOS) link. The second scenario uses line-of-sight (LOS) multihop relay links to connect source and destination. For both scenarios, we use two performance metrics: the probability of error and latency. The results of our analysis show the performance limits of this type of networks in practical situations. For example, the LOS network outperforms the NLOS one at an SNR of 7dB if the connected vehicles are moving at consistent velocities, and the number of hops is limited to 8.
