초록

본 논문에서, 우리는 TDMA 방식의 전술 데이터링크에서 원활한 전술 데이터의 분배를 위한 Dynamic TDMA 방식을 설계하였다. 기존의 전술 데이터링크는 고정된 시간 무선 자원을 이용했기 때문에 운용 도중 네트워크 상태에 따라 자원 현황을 변경하는 것이 불가능했다. 이러한 한계를 극복하기 위해 초기 타임슬롯 할당, 운용 중간 타임슬롯 할당, 타임슬롯 반납, 타임슬롯 회수와 같은 DTDMA 처리방식과 관련 메시지를 설계, 구현하고 그러한 상황을 모의하여 실험하였다. 이것으로 상황에 따라 타임슬롯 자원을 효율적으로 분배하여 사용하는 방식이 적용 가능함을 보였다. 따라서 차후 전술 데이터링크에 DTDMA 통신 관리를 할 수 있도록 연구를 계속할 것이다.

In this paper, we designed a dynamic TDMA scheme for smooth tactical data distribution in TDMA tactical datalinks. Since the existing tactical datalinks use fixed time radio resources, it is impossible to change the resource status according to network conditions during operation. To overcome these limitations, we designed, implemented, and simulated the DTDMA processing and related messages such as initial timeslot allocation, intermediate time slot allocation, time slot return, and timeslot retrieval. As a result, it was shown that the method of effectively allocating and using timeslot resources according to the situation is applicable. Therefore, we will continue research to manage DTDMA communication on tactical data link in the future.
