Abstract

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.

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.
