Analytical Design of Inter-Vehicular Communications for Collision Avoidance

We address the analytical design of a communications system that seeks to provide timely safety information for drivers who are unaware of an imminent collision. We develop a model to characterize the delay requirements needed to prevent such collisions. By simultaneously addressing the multi-user interference and propagation effects such as path loss and fading, we then analytically derive the optimal channel access probability and transmission range and rate of nodes that satisfy the delay requirements at a target success probability.
