Abstract

In this paper, we propose a virtual full-duplex relaying scheme based on data ferrying using two unmanned aerial vehicles (UAVs). By utilizing high mobility of two UAVs, the proposed relaying scheme can make each UAV communicate with a source node or a destination node when the UAV is near the source node or the destination node. The proposed relaying scheme can overcome the performance limitations of the half-duplex relaying and the implementation constraints of the full-duplex relaying. In addition, we propose an algorithm to shift the center point of two UAVs' trajectory with consideration of inter-relay interference (IRI). We show the simulation results of our proposed trajectory's center point shift algorithm. From the simulation results, it is shown that our proposed relaying scheme can achieve higher end-to-end spectral efficiency (SE) than the conventional static relaying scheme.

본 논문에서는 2개의 UAV(Unmanned Aerial Vehicle)를 중계기로 활용하는 데이터 페리 기반의 가상 전이중 중계전송 기법을 제안한다. 제안하는 기법은 2개의 UAV의 높은 이동성을 활용하여 데이터 페리 기반으로 통신하고자하는 대상과의 거리를 좁힌 후 송수신을 진행한다. 또한, 제안하는 기법은 가상 전이중 중계전송을 통해 반이중 중계전송의 성능 제약 및 전이중 중계전송의 구현 제약을 극복할 수 있다. 또한, IRI(Inter-Relay Interference)에 의한 성능 제약을 완화하기 위해 2개의 UAV에 대한 이동경로의 중심점을 조절하는 알고리즘도 제안한다. 시뮬레이션을 통해 제안하는 중심점 조절 알고리즘에 의한 중심점 이동 결과를 보인다. 제안하는 기법의 성능 평가를 진행한 결과, 기존의 고정된 중계기를 활용한 중계전송 방식에 비해 제안하는 중계전송 기법에서 더 높은 시스템 종단 간 평균 SE(Spectral Efficiency) 성능이 나타났다.
