Online Trajectory and Radio Resource Optimization of Cache-Enabled UAV Wireless Networks With Content and Energy Recharging
IEEE Transactions on Signal Processing(2020)
摘要
Recently, unmanned aerial vehicle (UAV)-assisted wireless communication technology has been proposed to exploit the favorable propagation property and flexibility of air-to-ground channels to support content-centric caching and enhance wireless network capacity. In this article, we propose an online UAV-assisted wireless caching design via jointly optimizing UAV trajectory, transmission power and ...
