초록

재난망용 LTE(Long Term Evolution)는 자가망을 기본으로 구축하고 일부 상용망 시설을 활용함으로써 비용을 절감하는 방향으로 구축되고 있다. 하지만, LTE 망은 기지국, 교환기 등 정보통신 기반시설 붕괴 시 망 생존성과, 폐쇄된 건물 내부 또는 지하구간 등 음영지역에서의 통신 커버리지가 취약하다는 한계가 있다. 본 연구에서는 기존에 활용하고 있는 검증된 기술들의 융합을 통해 망 생존성 기술을 제공하는 방안을 도출하였다. IoT시대의 도래에 따라, 사물과 환경 속에 내재된 스마트 센서는 컴퓨팅 파워와 네트워킹 모듈을 포함하여 망 생존성 구현을 위해 매우 유용한 기반을 제공한다. 본 연구에서는, 이러한 스마트센서의 특성을 기반으로 스몰셀 기술과 무선 네트워크 커버리지 확장기술을 융합함으로써 망 생존성을 효과적으로 구현하기 위한 USN(Ubiquitous Sensor Network) 싱크노드 아키텍처를 기획하였다. 사물과 환경 속에 내재된 컴퓨팅 파워는 재난재해 발생 시 유용한 자원으로 활용될 수 있을 것으로 기대된다.
