Joint Admission Control and Association for the Downlink of a mmWave Vehicular Network

In this study, we consider the problem of admission control for primary vehicles and association for secondary vehicles in a singe cell downlink vehicular network, based on vehicle-to-everything (V2X) architecture. We consider the network operates on millimeter wave (mmWave) communication at 60 GHz. Our objective is to determine the optimal topology of vehicle connectivity which maximizes the number of admitted primary vehicles, while associating all secondary vehicles to ensure the coverage. We cast the optimization problem as an ℓ0 minimization problem. This problem is known to be combinatorial and NP-hard. Hence, we propose a sub-optimal, two- stage algorithm to solve it. With numerical results we show that the proposed algorithm achieves close to optimal performance.
