Abstract

Internet-of-Things(IoT) is the computing environment to provide valuable services by interacting with multiple devices, where diverse devices are connected within the existing Internet infrastructure and acquire context information by sensing. As the concern of IoT has been increased recently, most of the industries develop many IoT devices. And, many people are focused on the IoT application that is utilizing different technologies, which are sensor network, communication technologies, and software engineering. Developing on-ground IoT application is especially even more active in progress depending on increasing of on-ground IoT devices because it is possible for them to access dangerous and inaccessible situation. However, There are a few studies related IoT. Moreover, since on-ground IoT application, which is different from typical software application, has to consider device's characteristics, communication, and surround condition, it reveal challenges, decreasing reliability. Therefore, in this paper, we analyze reliability challenges related to maturity and fault tolerance, one of reliability attributes, occurring in developing on-ground IoT applications and suggest the effective solutions to resolve the challenges. To verify proposed the challenges and solutions, we show result that is applying the solutions to applications. By presenting the case study, we evaluate the effectiveness of applying the solutions to the application.

사물 인터넷(Internet-of-Things, IoT)은 무선 인터넷으로 연결된 다양한 디바이스에게서 센싱을 통해 정보를 획득하고 여러 디바이스와 협업을 통해 사용자에게 유용한 서비스를 제공하는 컴퓨팅 환경을 말한다. 최근 사물 인터넷에 대한 관심이 높아짐에 따라 다양한 IoT 디바이스들이 개발되고 있으며, 특히 사람이 접근하기 어렵거나 위험한 환경에서 활용 가능한 지상용 IoT 디바이스에 대한 관심이 높다. 또한 이를 활용한 IoT 애플리케이션은 센서 네트워크나 통신 기술, 다양한 설계 기법 등의 기술이 활용되어 사용자에게 다양하고 유용한 기능을 제공한다. 이에 따라 지상용 IoT 애플리케이션에 대한 연구와 개발이 활발히 진행 중이다. 그러나 사물 인터넷은 최근 소개된 신기술이기 때문에 관련 연구에 대한 자료가 부족하며, 특히 지상용 IoT 애플리케이션은 기존의 전형적인 소프트웨어와는 다르게 디바이스의 특성이나 통신 환경, 주변 환경 등으로 인한 애플리케이션의 신뢰성을 저해하는 이슈들이 발생할 수 있다. 본 논문에서는 지상용 IoT 애플리케이션의 신뢰성 중 성숙도와 오류 관리성 관련 이슈들을 분석하고, 이를 효과적으로 해결할 수 있는 신뢰성 향상 기법들을 제시한다. 그리고 지상용 IoT 디바이스 중 Sphero Ball을 활용한 애플리케이션 개발을 통해 본 논문에서 제시한 이슈들을 도출하고 이를 해결하기 위한 솔루션을 적용 및 활용한 사례를 보여줌으로써 연구의 실효성을 보여준다.
