In this work, we consider behavioral security in unmanned aerial vehicle (UAV) communication networks, which means the UAVs implement the communication process without causing third-party perception. Specifically, we consider a scenario where the UAV aims to transmit a message to Bob during its flight as undetectably as possible in the presence of a warden Willie. We jointly optimize the UAV’s transmit power and flight trajectory in order to maximize Willie’s detection error probability. To solve the non-convex optimization problem, we decompose the problem into two sub-problems and propose an iterative approach that optimizes the trajectory and power allocation in an alternating manner. Simulation results are provided to verify the effectiveness of the proposed scheme.
