초록

해상작전 수행의 성패는 서로간의 신속하고 정확한 의사전달과 원활한 통신망 구축이 우선되어야 한다. 군의 주통신망인 위성은 적의 전파교란 및 고정 안테나의 취약점으로 예비 통신망 구축이 반드시 필요하다. 따라서 군은 작전 통신망을 음성위주에서 문자 기반의 무선 통신망으로 전환하여 왔다. 본 논문에서는 현재 해군에서 운용중인 전술데이터링크(Link-11)의 주 통신방식인 Roll Call을 기본으로 하여 개선된 통신방식을 제안하였다. 시뮬레이션을 통해 기존 방식과 성능을 비교한 결과 제안된 통신방식(Selective Broadcasting)은 단위 프레임별 전송 소요시간이 Roll Call 대비 4.3배, Round Robin & Broadcasting 대비 6.3배 단축됨을 확인하였으며, 직접적인 수신율이 높을수록 소요시간은 최대 1.6배 단축됨을 입증하였다.

The success of naval operation prioritizes the implementation of a robust communication network that delivers accurate and prompt communications to one another. The satellite, which is the main communication network of the military, is required to construct a preliminary communication network because of the enemy radio disturbance and weak point of fixed antenna. The military operational communication network has been in transition from voice-centered wireless communication network to text message-based communication network. In this paper we suggest an enhanced communication method built on Roll Call, the main communication method of ROK Navy operating tactical data link called Link-11. Simulation results display that the proposed method reduces the transmission time per unit frame by 4.3 times compared to the Roll Call and 6.3 times compared with the Round Robin & Broadcasting; it is also proved that the higher the direct reception rate, the shorter the transmission time required by 1.6 times maximum.
