Modeling Edge-to-Cloud Offloading Workloads for Autonomous Vehicles
This addresses workload modeling for autonomous vehicle data offloading, which is incremental as it builds on existing traffic models with domain-specific adaptations.
The paper tackles the problem of modeling edge-to-cloud data offloading workloads for autonomous vehicles, which existing studies fail to capture accurately. The results show that workload scales with vehicle penetration, exhibits temporal structure and spatial imbalance across access points, and differs from baseline traffic models.
Autonomous vehicles generate large volumes of data for applications such as fleet monitoring, model retraining, and high-definition map updates. Existing studies often rely on generic traffic traces, which do not capture the characteristics of autonomous driving workloads. This paper proposes a system-level workload modeling framework for vehicle-to-cloud data. We classify offloaded data into three types: telemetry, event-driven fleet learning, and high-definition map updates, while we model their generation using a parameterized formulation based on empirical data. Using a real-world mobility trace from Munich, we analyze the resulting workloads over time and space. The results show that workload scales with vehicle penetration, exhibits temporal structure and spatial imbalance across access points, and is distinguished from baseline traffic models.
