초록

우리군에서는 지상공간에서의 TICN과 우주공간에서의 차기위성을 연동한 미래전술네트워크 구축을 추진하고 있다. 그러나, 위성의 낮은 대역폭과 높은 운영비용에 의하여, 위성을 통한 모든 전술 정보의 유통에는 한계가 있다. 이를 극복하기 위하여, 공중망을 구축하는 연구가 활발히 진행되고 있다. 본 논문에서는 지상 노드의 단절에 대응하여 공중중계망과 지상전술망을 효과적으로 연동하기 위한 구조와 운영하는 방안을 제안한다. 그리고, 이의 효과도를 분석하기 위한 방안을 함께 제안한다. 효과도 분석 실험 결과는 공중중계망의 운영은 지상전술망의 장애상황에 효과적으로 대처 가능함을 보여준다.

Korean army has been trying to construct a future tactical network in collaboration with TICN at the ground level and the next-generation military satellite system in the space level. However, due to the low bandwidth and high operational cost, the satellite system has the limitation to exchange all kind of tactical information through it. To overcome the limitation, there have been several researches to construct airborne networks. In this paper, we propose an effective interworking architecture and operation scheme between terrestrial tactical networks and aerial relay networks to counteract against the communication breaks of terrestrial terminals. And, we also propose a way to analyze its effectiveness. The experimental results show that the interworking of aerial relay networks can manage the failure situations in terrestrial tactical networks very effectively.
