Secure Offloading in NOMA-Aided Aerial MEC Systems Based on Deep Reinforcement Learning
Hongjiang Lei, Mingxu Yang, Ki-Hong Park +1
Mobile edge computing (MEC) technology can reduce user latency and energy consumption by offloading computationally intensive tasks to the edge servers. Unmanned aerial vehicles (U…
Proactive Eavesdropping in Relay Systems via Trajectory and Power Optimization
Qian Dan, Hongjiang Lei, Ki-Hong Park +2
Wireless relays can effectively extend the transmission range of information. However, if relay technology is utilized unlawfully, it can amplify potential harm. Effectively survei…
Two Birds With One Stone: Beamforming Design for Target Sensing and Proactive Eavesdropping
Qian Dan, Hongjiang Lei, Ki-Hong Park +2
This work studies the beamforming design in the joint proactive eavesdropping (PE) and target sensing (TS) systems. The base station (BS) wiretaps the information transmitted by th…
Multi-UAV Trajectory Design for Fair and Secure Communication
Hongjiang Lei, Dongyang Meng, Haoxiang Ran +3
Unmanned aerial vehicles (UAVs) play an essential role in future wireless communication networks due to their high mobility, low cost, and on-demand deployment. In air-to-ground li…
3D Trajectory Design for Energy-constrained Aerial CRNs Under Probabilistic LoS Channel
Hongjiang Lei, Xiaqiu Wu, Ki-Hong Park +1
Unmanned aerial vehicles (UAVs) have been attracting significant attention because there is a high probability of line-of-sight links being obtained between them and terrestrial no…
Aerial Relay to Achieve Covertness and Security
Jiacheng Jiang, Hongjiang Lei, Ki-Hong Park +2
In this work, a delay-tolerant unmanned aerial vehicle (UAV) relayed covert and secure communication framework is investigated. In this framework, a legitimate UAV serves as an aer…
