Efforts are currently underway in the U.S. Air Force to utilize a heterogeneous set of physical links (RF, Optical/Laser and SATCOM) to interconnect a set of terrestrial, space and highly mobile airborne platforms (satellites, aircrafts and Unmanned Aerial Vehicles (UAVs)) to form an Airborne Network (AN). We propose an architecture for an Airborne Network to provide a stable operating environment for an AN. We design algorithms to compute the speed of movement of the airborne platforms, so that the resulting dynamic topology remains connected at all times. The ANPs are also required to provide coverage in the air corridor at all times. We design algorithms to provide time invariant coverage in the air corridor with moving ANPs whose coverage volume changes with its movement. We also design routing algorithms for such networks under two different types of channel conditions. If time permits, we will also discuss fault scenario in such networks. Faults are likely to be localized in these networks where an enemy attack may inflict localized damage to the network. To capture the notion of locality in fault tolerance capability of such networks, we introduce the notion of region-based connectivity. The attractive feature of the region-based connectivity as a metric is that it can achieve the same level of fault-tolerance as the metric connectivity, but with much lower transmission power for the nodes.
