- W2920362693 abstract "This paper considers the use of an unmanned aerial vehicle (UAV) as a mobile relay to enhance the physical layer security in wireless wiretap channels. Specifically, we consider a scenario where a source (Alice) transmits signals to a destination (Bob) with the aid of the UAV in the presence of an eavesdropper (Eve). It is assumed that the UAV is able to cache the data received from Alice and then send to Bob in a secret fashion. Joint optimization of the communication resources and the UAV trajectory for maximizing the accumulated secrecy rate is investigated. While the joint design problem is non-convex, we propose an iterative algorithm based on successive convex approximation. Simulation results are presented to provide the insights into the proposed resource allocation strategy and trajectory for secure rate maximization and demonstrate how the UAV-aided rely can significantly enhance secrete rate transmissions." @default.
