Full title—Addressing Control Challenges in Vehicular Networks through O-RAN: a Novel Architecture and Simulation Framework
This article promotes a novel integration architecture that ensures the V2X control within O-RAN. We propose a novel architecture that establishes a low frequencies O-RAN-based control plane to ensure reliable and efficient multihops connectivity among CAVs at millimeter wave (mmWave).
To examine and test the technological feasibility of this integrated architecture, we extend current Network Simulator 3 (ns-3) modules, leading to a simulation framework for experimenting with O-RAN-empowered V2X system. Such an integrated framework is used to show the benefits in a specific V2V challenge: link and relays selection.
This case study serves as a practical example of a new O-RAN solution that effectively addresses the challenges of V2X communications. Numerical results showcase the improved reliability up to 60 to distributed and unmanaged solutions, supporting the viability of the proposed architecture.
