Technology independent scheduling architecture for V2X communications: A flexible approach

Vehicle-to-Everything (V2X) communications encapsulate significant challenges as a result of the vast number of wireless technologies deployed, nodes mobility and large applications range. One of the greatest challenges is to provide adequate QoS guarantees even in this demanding environment. State-of-the-art solutions for QoS provisioning over wireless links are based on cross-layering packet schedulers that deal both with the QoS guarantees and the wireless link issues. Unfortunately, such an approach is not flexible and requires technology-dependent solutions, with the definition of a different software version for of the each technology deployed. To overcome this issue, we design a modular architecture which permits the use of existing high-performance packet schedulers for wired links over generic wireless technologies, as they are, and at the same time allows the flexibility to adapt to different channel conditions. We also provide a mathematical analysis of the QoS bounds of this novel architecture together with simulations analysis to validate it. This approach paves the way for efficient QoS provisioning and throughput-boosting in V2X systems.
