Abstract

Computational offloading transfers tasks from resource-constrained devices to more capable servers or cloud platforms, improving processing speed and user experience. Open radio access networks (O-RAN's) disaggregated architecture and open interfaces make it suitable for offloading delay-sensitive tasks, enhancing real-time application performance. This study focuses on task offloading in O-RAN, a reference network architecture. Although research on O-RAN is limited, existing work lacks a comprehensive approach to offloading, including offloading layer determination, node selection, and resource allocation based on task types and their latency needs. We propose a delay-aware task offloading framework within O-RAN to support diverse delay requirements, improving offloading efficiency. To address this, we introduce COOR (Computation Offloading for O-RAN), a centralized approach that leverages network-wide data. Using Genetic Algorithms (GA), we manage computational complexity effectively. Simulation results show COOR's superior performance in reducing latency.
