공공안전 환경을 위한 사물인터넷 통신망 기술 개요

  • Published : 2017.05.31

Abstract

사물 인터넷(IoT: Internet of Things)은 세상의 모든 사물들을 인터넷과 상호 연결하여 사람과 사물, 사물과 사물 간에 언제 어디서나 상호 소통할 수 있도록 하는 기술이다. 사물 인터넷의 네트웍 기술은 통신 인프라 (Infrastructure) 가 없는 환경에서 이기종 다양한 디바이스를 연결하는 기술로서 재난복구 및 구조와 같은 공공안전 분야에도 적용할 수 있는 애드 혹(ad-hoc) 형태의 네트웍 기능을 제공한다. 특히, 사물 인터넷의 특성상 저사양(low power) 기기들의 사용이 증가하고 있기 때문에 여러 표준화 단체에서 사물 인터넷 특성에 따른 요구사항을 지원하기 위한 표준화 활동을 활발하게 진행중이다. 본 고에서는 급변하는 통신 기술 환경에서 공공안전 분야에 적용할 수 있는 사물 인터넷 통신망을 이루기 위해 필요한 수많은 기술 중에서 주목할 필요가 있는 RPL과 TSCH 기술에 대해 소개하고자 한다.
