In this paper, the position control of multiple unmanned aerial vehicles, acting as cooperative jammers, is proposed to improve the security level of a legitimate ground transmission, where a precoder is designed to nullify the jamming signals at the legitimate receiver. In this scenario, the maximization of the weighted secrecy coverage, which measures the efficiency of cooperative jamming over a confined region, is addressed by following a multi armed bandit-based algorithm. The results show that our proposal converges to the one obtained by exhaustive search, and it shows significant improvement over a projected gradient-descent benchmark, while offering a shorter running-time. The results show that, for the considered system and the employed precoder, the inclusion of more than two UAVs does not lead to significant advantages in terms of secrecy performance.
