Trajectory optimization of unmanned aerial vehicles (UAVs) operating as flying base stations (FBSs) evolved a novel integration component in beyond 5G (B5G) networks and has recently received significant research attention. Notably, the vast majority previous mainly concentrated on case single terrestrial macro station (BS) which is used depot for multiple FBSs. In this article, we focus more g...

Area coverage is an important task for mobile robots, with many real-world applications. Motivated by potential efficiency and robustness improvements, there is growing interest in the use of multiple robots in coverage. Previous investigations of multi-robot coverage algorithms focused on the improved efficiency gained from the use of multiple robots, but did not formally addressed the potenti...
