Estimation method of airspace connectivity probability in military AANET

Connectivity is the premise and foundation of networking and routing. For the probabilistic flight path of military aircraft resulting in the difficulty of Aeronautical Ad hoc NETwork (AANET) research, an estimation method of connectivity probability is proposed. The method takes airspace as the research object, starts with actual flight characteristics, and applies conclusions of random waypoint mobility model. Building a connectivity model by establishing Airspace Unit Circle (AUC) from the perspective of circle-circle coverage, the method obtains a theory of airspace network connectivity. Experiment demonstrates its correctness. Finally, according to the actual condition simulation, relationship between the number of aircraft, communication radius, and the flight area under connectivity probabilities is achieved, results provide reference for creating a network that under certain aerial combat condition.
