사물인터넷(IoT)은 다양한 디바이스가 유무선 네트워크를 통해 연결되어 정보를 수집, 처리, 교환, 공유하는 환경이다. 대표적 디바이스가 스마트폰 같은 모바일 IoT 디바이스인데, 사용자에게 고성능서비스를 제공하기 위해 파워를 많이 소비하지만 상시 공급할 수 없어서 주어진 IoT 환경에 적합하게 파워 관리를 하는 것이 필수적이다. 하지만 기존 모바일 IoT 디바이스의 파워 관리에는 AP, AP 내/외부HW 모듈, OS, 플랫폼, 어플리케이션 등 다양한 요소가 복잡하게 얽혀 있어서 이 관계를 쉽게 파악하고관리하는 체계적인 방법이 필요하다. 또한 파워 관리와 연관된 다양한 관리 정책, 운영 환경, 알고리즘 등가변 요소를 분석하고 이를 파워 관리 개발에 반영하는 것이 필요하다. 본 논문에서는 이러한 문제점을해결하고 모바일 IoT 디바이스 파워 관리를 체계적으로 개발하기 위한 공학 원칙과 이를 기반으로 한 방법을 제안한다. 실행가능성 검증을 위해 커넥티드 헬멧 시스템 파워 관리가 사례연구로 사용되었다.
