  UAV-Based Autonomous Metaverse Data Collection

Unmanned aerial vehicles (UAVs) are promising for providing communication
services due to their advantages in cost and mobility, especially in the
context of the emerging Metaverse and Internet of Things (IoT). This paper
considers a UAV-assisted Metaverse network, in which UAVs extend the coverage
of the base station (BS) to collect the Metaverse data generated at roadside
units (RSUs). Specifically, to improve the data collection efficiency, resource
allocation and trajectory control are integrated into the system model. The
time-dependent nature of the optimization problem makes it non-trivial to be
solved by traditional convex optimization methods. Based on the proposed
UAV-assisted Metaverse network system model, we design a hybrid framework with
reinforcement learning and convex optimization to {cooperatively} solve the
time-sequential optimization problem. Simulation results show that the proposed
framework is able to reduce the mission completion time with a given
transmission power resource.
