09 - Air Transport System EfficiencyCLUSTER STRUCTURE AND GATEWAY AVAILABILITY OF AD-HOC COMMUNICATION NETWORKS IN THE NORTH ATLANTIC AIRSPACET. Marksą, A. Hillebrechtą; ąGerman Aerospace Center, Germany The North Atlantic airspace is one of the busiest airspaces in the world, while at the same time lacking radar coverage and exhibiting limited data link capabilites. In our paper we analyze ad-hoc communication networks among airplanes in terms of cluster structure and gateway availability by time series and by per scenario analyses and show the dependencies to higher level scenario parameters. |
