In Mobile Edge Computing (MEC) systems, Unmanned Aerial Vehicles (UAVs) facilitate Service Providers (ESPs) offering flexible resource provisioning with broader communication coverage and thus improving the Quality-of-Service (QoS). However, dynamic system states various traffic patterns seriously hinder efficient cooperation among UAVs. Existing solutions commonly rely on prior knowledge or complex neural network models, lacking adaptability causing excessive overheads. To address these critical challenges, we propose DisOff, a novel profit-aware cooperative offloading framework in UAV-enabled MEC lightweight Deep Reinforcement Learning (DRL). First, design an improved DRL twin critic-networks delay mechanism, which solves Q-value overestimation high variance approximates optimal UAV allocation. Next, develop new multi-teacher distillation mechanism for proposed model, where policies of multiple UAVs are integrated into one agent, compressing model size while maintaining superior performance. Using real-world datasets user traffic, extensive experiments conducted to validate effectiveness DisOff. Compared benchmark methods, DisOff enhances ESP profits reducing training costs.

The proliferation of advanced embedded and communication technologies has facilitated the possibility modern Intelligent Transportation System (ITS). hierarchical nature such large-scale distributed systems brings obvious challenges in creating a scalable sustainable computing environment, hence development application edge intelligence become critical. Federated learning (FL), as an emerging machine paradigm, aims to offer secure knowledge sharing effective across multiple devices. However, conventional FL may fall into trouble when facing network-agnostic with fast moving devices changing network attributes. In this study, we propose Adaptive Segmentation enhanced Asynchronous Learning (AS-AFL) model, aiming improve efficiency reliability ITS via decentralized fashion. Specifically, meta-learning based adaptive segmentation scheme is designed automatically separate client nodes (e.g., vehicles) groups according their homogeneous An integrated aggregation mechanism then developed realize horizontal among group similar so-called intra-group synchronous aggregation, while allowing vertical different inter-group asynchronous aggregation. Experiment evaluation results on open-source dataset demonstrate outstanding performance our proposed compared several schemes scenario.

As mobile communication technologies advance, networks become increasingly complex, and user requirements diverse. To satisfy the diverse demands of users while improving overall performance network system, limited wireless resources should be efficiently dynamically allocated to them based on magnitude their relative location base stations. We separated problem into four constrained subproblems, which we then solved using a safe reinforcement learning method. In addition, design reward mechanism encourage agent cooperation in distributed training environments. test our methodology simulated scenario with thousands hundreds According experimental findings, method guarantees that over 95% are satisfied also maximizing system throughput.
