Abstract
With the on-demand deployment and high flexibility of the unmanned aerial vehicle (UAV), carrying mobile edge computing (MEC) systems can efficiently relieve the pressure of the explosive growth of data traffic. UAVs adopt line-of sight (LOS) transmission with broadcast characteristics, the information they transmit to ground users (GUs) are easy to be eavesdrop by malicious eavesdroppers. Therefore, secure communication is worth studying in UAV-MEC networks. In this paper, we propose a Dual-UAV-MEC system where GUs offload part of the tasks to UAV server carrying MEC for calculation in the presence of the eavesdropping of offloading information by UAV Eavesdropper, Jammer on the ground sends interference signals to reduce eavesdropping. We propose a secure communication scheme with time division multiple access (TDMA) to maximum the GUs minimum secure calculation capacity. Specifically, we optimize the UAV Servers trajectory and allocate wireless resources which include time allocation factor and local calculation. Numerical results show that the method we proposed efficiently increases the secure calculation capacity of the system.
