Joint Optimization of Offloading, Phase-Shift, Trajectory and Resource Allocation in Priority-Aware IRS-Assisted UAV-MEC Systems

This paper considers task priority and integrates intelligent reflecting surface (IRS) into traditional UAV-MEC to enhance offloading efficiency and indicates that the system utility of the proposed method is dramatically higher than other benchmark schemes under different scenes.

Utility Maximization in Multi-Functional UAV- and IRS-Aided SWIPT-MEC Networks: A Dynamic Feature Extraction-Based Optimization Approach

UAV (unmanned aerial vehicle) and IRS (intelligent reflecting surface) assisted mobile edge computing (MEC) faces low quality of service (QoS) due to the single functionality of UAV and IRS. In response, we propose a simultaneous wireless information and power transfer (SWIPT)-MEC network aided by multi-functional UAV...

Hierarchical Meta-Graph Reinforcement Learning for Collaborative GenAI Model Caching and Inference Scheduling

Enabling collaborative generative AI (GenAI) inference at the network edge is challenging due to limited caching capacity, heterogeneous computing resources, and highly dynamic, latency-sensitive service demands. In this paper, we investigate the joint optimization of GenAI model caching, inference offloading, and reso...
