Abstract

This paper investigates unmanned aerial vehicle (UAV) enabled secure communication systems where a mobile UAV wishes to send confidential messages to multiple ground users with the aid of a cooperative UAV which transmits the jamming signal. In this system, we maximize the minimum secrecy rate among the ground users by jointly optimizing the trajectory and the transmit power of the UAVs as well as the user scheduling. To solve this non-convex problem, we adopt block successive upper bound minimization techniques which address a sequence of approximated convex problems for each block of variables to obtain a local optimal solution. Numerical results verify that the proposed algorithm outperforms baseline methods.
