Physical Layer Security for NOMA Transmission in mmWave Drone Networks
IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY, 70(4), 3568–3582.
author keywords: NOMA; Unmanned aerial vehicles; Shape; Wireless networks; Receivers; Jamming; Decoding; Millimeter-wave (mmWave); non-orthogonal multiple access (NOMA); physical layer security (PLS); protected zone; unmanned aerial vehicle (UAV)
TL;DR:
This work proposes a protected-zone approach to enhance the secrecy-rate performance by preventing the most vulnerable subregion (outside the user region) from the presence of malicious receivers, and shows that the optimal protected zone shape for mmWave links appears as a compromise between protecting the angle versus distance dimension.
