Proportional Fair Information Freshness Under Jamming

The success of a UAV mission depends on communication between a GCS (Ground Control Station) and a group of UAVs. It is essential that the freshness of the commands received by UAVs is maintained as mission parameters often change during an operation. Ensuring the freshness of the commands received by UAVs becomes more challenging when operating in an adversarial environment, where the communication can be impacted by interference. We model this problem as a game between a transmitter (GCS) equipped with directed antennas, whose task is to control a group of UAVs to perform a mission in a protected zone, and an interferer which is a source spherically propagated jamming signal. A fixed point algorithm to find the equilibrium is derived, and closed form solutions are obtained for boundary cases of the resource parameters.
