Systematic Medium Access Control in Hierarchical Airborne Networks with Multi-Beam and Single-Beam Antennas

A heterogeneous medium access control (MAC) scheme (with both scheduled and random communications) is proposed for airborne networks. These networks have a hierarchical topology with a small number of powerful aircraft nodes with multibeam antennas and long-distance links at the higher level, and high-density unmanned aerial vehicle (UAV) nodes with single-beam directional antennas at the lower le...
