Description
Summary:In this paper, we study unmanned aerial vehicle (UAV) trajectory control and channel assignment for UAV-based wireless networks with wireless backhauling. Our design aims to maximize the sum rate achieved by ground users while satisfying their data demand where spectrum reuse and co-channel interference management are considered. To tackle the underlying non-convex mixed-integer nonlinear optimization problem, we use the alternating optimization approach where we iteratively optimize the channel assignment and UAV trajectory control until convergence. Particularly, we propose an efficient heuristic algorithm to solve the channel assignment sub-problem. Moreover, the successive convex approximation (SCA) is used to solve the non-convex UAV trajectory control sub-problem. Via extensive numerical studies, we illustrate the effectiveness of our proposed design considering different network settings.
