본 논문은 정찰 임무를 수행하는 무인지상차량이 동적으로 변화하는 환경에서도 통신 연결성을 유지할 수 있도록 지원하는 통신계획 알고리즘을 제안한다. 제안된 알고리즘은 임무 경로, 무인지상차량 수, 최대 통신 단절 허용 거리를 입력으로 받아 임무 경로에서 발생 가능한 통신 단절을 사전에 파악하고 이를 해결하기 위해 무인지상차량의 최적 중계 지점을 도출하여 임무를 성공적으로수행할 수 있는 통신 계획을 수립한다. 시뮬레이션 결과, 대한민국의 산악 지형과 같은 복잡한 환경에서도 높은 성능을 보임을 확인하였으며, 이를 통해 제한된 자원과 다양한 지형 조건에 대해서도 최적의 통신 계획을 제공하여 운용자의 의사결정에 실질적인 도움을 줄 수 있음을 확인하였다.
Abstract
This study proposes a communication planning algorithm to support unmanned ground vehicle(UGV) in maintainingcommunication connectivity during reconnaissance missions, even in dynamically changing environments. Theproposed algorithm utilizes input data such as mission routes, the number of UGVs, and the maximum allowablecommunication disconnection distance to preemptively identify potential communication disconnections along themission path. It then determines the optimal relay points for UGVs, establishing a communication plan thatensures mission success. Simulation results demonstrate that the algorithm performs effectively in complex environments,such as mountainous terrains in South Korea. These findings confirm its capability to provide optimal communicationplans under resource-constrained and diverse terrain conditions, ultimately offering practical assistance to operatorsin decision-making.
