Beyond Average-Channel-Based Rate Approximations: UAV Trajectory and Scheduling Optimization With Expected Rate Consideration
A new method ensures reliable drone-to-ground communication by accurately modeling unpredictable wireless signals.
Researchers Gitae Park and Kisong Lee developed a novel optimization algorithm for UAV-assisted wireless networks. It moves beyond standard 'average channel' approximations by using quadrature-based methods to model signal fading and line-of-sight probability. This ensures strict minimum data rate guarantees for ground users. The algorithm jointly optimizes drone trajectory, user scheduling, and time slots, achieving significantly faster mission completion than conventional methods while maintaining reliable connectivity.
