Vehicular Cloud With Threshold-Based Prioritized Task Service and IEEE 802.11bd Communication

Abstract

Vehicular cloud (VC) computing which integrates cloud computing principles with data communication through vehicular ad-hoc networks (VANETs) is the foundation for intelligent transportation systems (ITS). In this article, we propose a VC system where vehicles offload task computation to other vehicles in the vicinity through a threshold-based prioritization scheme, using IEEE 802.11bd communication technology to interconnect the vehicles. We model the VC as an $M/G/m$ queuing system with task priority structure aligned to the priority structure of IEEE 802.11bd communications, taking into account distance coverage and priority thresholds that aim to enhance resource utilization across vehicles. Key performance metrics are analyzed under various traffic conditions. Our results demonstrate reliable and efficient priority-based resource management in the cloud network emphasizing the potential of this approach to meet the evolving demands of ITS.
