Abstract

We propose control mechanism of UAV(Unmanned Aerial Vehicle) group for making the communication network to the base station after the target is found. We assume UAVs can communicate to each other by wireless LAN without existing communication infrastructure. UAVs started to fly in linear formation, after finding target, UAVs move to the base station to send the information about the target. At least one UAV stays the position that the target is found. This paper explains the mechanism supporting reliable connectivity during UAV group's flying. We verify the proposed scheme and evaluate the performance through NS-2 simulation. The proposed scheme can be applied to the disaster area and war zone, which the existing communication infrastructure cannot be worked.

본 논문에서는 UAV(Unmanned Aerial Vehicle)을 이용하여 목표물을 찾은 후 기지국까지 통신 네트워크를 제공하기 위해 UAV 집단을 제어하는 방안을 제안한다. 기존의 통신 시설을 이용하지 않고 UAV들 간에만 무선 랜 통신이 가능하다고 가정한다. 제안 방안은 UAV들이 탐색지역 내에 위치한 목표물을 찾기 위해 기지국으로부터 선형 형태로 출발하고 목표물을 찾은 후에, 목표물에 대한 정보를 기지국까지 전달하기 위하여 UAV 그룹을 이동시킨다. 이 때, 목표물을 발견한 최소 하나의 UAV는 그 위치에 머무른다. 본 논문은 기지국으로의 이동하는 과정에서 안정적인 연결성을 유지하기 위한 방법을 설명한다. NS-2를 사용한 모의실험을 통하여 제안되는 기법을 검증하고 성능을 평가한다. 제안 기법은 기존의 통신 시설을 이용할 수 없는 재난 상황이나 전시 상황과 같이 UAV가 사람을 대신하여 목표물을 감지하며 기지국으로 신속히 전달하는데 유용하게 사용될 수 있다.
