Underground environments, including tunnels, mines, and collapsed structures, impose severe constraints on unmanned aerial vehicle (UAV) communication because of signal attenuation, nonline-of-sight (NLoS) propagation, intermittent connectivity, and global positioning system (GPS)-denied operation. Conventional communi...
