Cooperative unmanned aerial vehicles (UAVs) are suitable for complex missions in denied environments. In scenarios where denial is potentially hostile, the use of stealth approaches is essential, as it allows such missions to be conducted in the proximity of threatening radars and weapons. We propose a model that allows autonomous UAVs to dynamically and cooperatively reduce their exposure to threats by adopting a stealth policy, in which they turn off their communication radios once a threat is detected. We named this approach of cooperative model as Stealth UAV Networks (SUN). Our model also encompasses control laws for connectivity maintenance, collision avoidance between UAVs, flight path planning, coverage area and robustness to communication failures improvement. We validated the approach with different combinations of control laws, number of UAVs and scenario hostility. The exposure of UAVs to threats decreased by at least 61% and at most 96% when the stealth policy is active, considering all simulation settings. Thus, highlighting that the stealth policy can be successfully used in missions that demand the increase of coverage area rate or robustness to failures. (AU) | |
