Unmanned Aerial Vehicle (UAV)-assisted mobile edge computing (MEC) leverages UAVs’ mobility and cost-effectiveness to handle computation-intensive tasks at the network edge. However, limited energy supply and hardware costs can cause high CPU temperatures due to excessive heat dissipation when processing demanding tasks. To address this, we study a UAV-assisted MEC network where the UAV provides computing services during flight, aiming to minimize users’ average computation time under CPU temperature constraints. We jointly optimize the UAV’s trajectory, resource allocation, and task scheduling, breaking the problem into four subproblems solved iteratively. Simulations confirm that the proposed algorithm meets thermal constraints while reducing average computation time.
