Aligning Priorities: Interconnecting Vehicular Cloud Using IEEE 802.11bd Communications

This study addresses the challenges faced by Vehicular Ad-Hoc Networks (VANETs) in intelligent transportation systems (ITS), including high vehicle mobility and dynamic network topologies that affect connectivity and data transmission reliability. We propose an integrated approach that combines Vehicular Clouds (VCs) with IEEE 802.11bd communication technology, modeling the vehicular cloud as an M/G/m queuing system. To align with IEEE 802.11bd's priority structure, we implement a priority scheme that limits task execution by each On-Board Unit (OBU) based on priority class. Additionally, the system enhances resource utilization through task delegation considering distance coverage and priority thresholds. Performance metrics are analyzed under varying traffic conditions, demonstrating the effectiveness of priority-based resource management to meet the evolving demands of ITS.
