Adaptive Edge Resource Management Through Deep Reinforcement Learning Techniques

Abstract

Edge computing has emerged as a foundational paradigm for intelligent digital infrastructure because it reduces latency, improves bandwidth utilization, and enables real-time analytics close to data sources. Yet modern edge environments remain highly volatile. Resource availability changes continuously. IoT traffic fluctuates unpredictably. Mobile users migrate across heterogeneous networks. Conventional heuristic-based schedulers struggle to maintain stable Quality of Service (QoS) under such conditions. Deep Reinforcement Learning (DRL) offers an adaptive decision-making framework capable of learning dynamic resource allocation strategies directly from complex environments. This paper investigates adaptive edge resource management through DRL-driven optimization models for computation offloading, task scheduling, bandwidth allocation, energy efficiency, and autonomous orchestration in distributed edge ecosystems. The study synthesizes recent advances between 2020 and 2025 across edge intelligence, federated learning, multi-agent reinforcement learning, and AI-driven autonomous networking. A layered DRL-enabled edge orchestration framework is proposed to optimize latency, throughput, energy consumption, and load balancing simultaneously. The research also formulates two research questions focused on scalability and adaptive scheduling under heterogeneous workloads. The proposed methodology integrates Proximal Policy Optimization (PPO), Deep Q-Networks (DQN), Multi-Agent Deep Deterministic Policy Gradient (MADDPG), and federated reinforcement learning within a cloud-edge continuum. Comparative analysis indicates that DRL-based adaptive management substantially improves response latency, energy utilization, and computational efficiency compared with static and rule-based schedulers. The paper identifies unresolved challenges involving reward engineering, explainability, convergence stability, privacy preservation, and large-scale deployment in 6G-enabled edge systems. The findings demonstrate that DRL-driven adaptive orchestration can become a central mechanism for autonomous edge intelligence in next-generation AI-native communication infrastructures.
