As the frequency of natural disasters increases, study emergency communication becomes increasingly important. The use federated learning (FL) in this scenario can facilitate collaboration between devices while protecting privacy, greatly improving system performance. Considering complex geographic environment, flexible mobility and large radius unmanned aerial vehicles (UAVs) make them ideal auxiliary for wireless communication. Using UAV as a mobile base station better provide stable signals. However, number ground-based IoT terminals is closely distributed, so if all transmit data to UAV, will not be able take on computation tasks because its limited energy. In addition, there competition spectrum resources among many terrestrial devices, transmitting bring about an extreme shortage resources, which lead degradation model This indelible damage rescue disaster area threaten life safety vulnerable injured. Therefore, we user scheduling select some participate FL process. order avoid resource waste generated by device prediction, multi-armed bandit (MAB) algorithm equipment evaluation. fairness issue selection, try replace single criterion with multiple criteria, using freshness energy consumption weighting reward functions. state art our approach demonstrated simulations datasets.

With the ongoing advancement of electric power Internet Things (IoT), traditional inspection methods face challenges such as low efficiency and high risk. Unmanned aerial vehicles (UAVs) have emerged a more efficient solution for inspecting facilities due to their maneuverability, excellent line-of-sight communication capabilities, strong adaptability.
