On air defense communications network connectivity

The authors address the issue of communication network survivability and provide a quantitative measure of the time-varying connectivity of space and ground multimedia networks operating in stressed environments. This measure allows comparison of very different network architectures in terms of connectivity. A generic SBR (Space-Based Radar) constellation was selected for study of the communications connectivity. The SBR, consisting of constellations of low Earth orbit satellites, will require dynamic, robust communication protocols and networks to support the various missions for the Air Force, Navy, and other military organizations. The authors present a methodology that can be used to define connectivity requirements once the threat and system parameters are better defined.<
