Naming Conventions

x_bs: Prefix indicating the number of Base Stations (BS) capturing and transmitting data in the scenario.
x_uav: Prefix indicating the number of Drones (UAV) flying and collecting data.
z_traj: A fixed-altitude zig-zag path designed for uniform area coverage.
rand_traj: Continuous curvilinear trajectories generated via Markov Chains in 3D space, heavily used for testing dynamic and collaborative tracking.
