Abstract:

In order to solve the security hazard caused by the exposure of offloading and transmission behaviors in unmanned aerial vehicle (UAV) assisted mobile edge computing (MEC) system, a UAV-assisted MEC covert communication model based on non-orthogonal multiple access is proposed. Due to the small battery capacity and inconvenient charging of UAVs, energy consumption optimization of the systems is of great concern. Regarding the proposed model, under the condition of meeting the system's concealment requirments, the goal is to achieve the minimum total system enenrgy consumption. Grouping of ground devices, flight trajectory of UAVs, the power of the artificial noise transmitted by UAVs, and allocation of UAV computing resources is achieved. Simulation results show that under the same convert constraints, the energy consumption of the proposed energy consumption optimization strategy for safe MEC systems is lower than the existing strategies.

Key words: mobile edge computing (MEC), unmanned aerial vehicle (UAV), non-orthogonal multiple access, covert communication, energy consumption
