Abstract

Internet of Things (IoT), one of the emerging research areas, is the computing paradigm where various things connect to the network and cooperate with their neighbors to reach common goals. Computing with IoT devices opens up a new array of opportunities for providing value-added smart services and applications to end users. That is, IoT devices play an important role of providing useful services to the users. However, the states of IoT devices are dynamically changed at runtime, which come from their mobility, network connectivity, and a battery drain problem. This dynamism results in difficulties in managing these IoT devices. In this paper, we propose a framework to manage those IoT devices with dynamism. Hence, we first derive issues from IoT devices' dynamism. And, we define a set of requirements to manage the IoT devices and present a framework to manage the device dynamism. The framework is equipped by a device discovery method, a device status monitoring method, a device selection and connection method, and a device replacement method. Finally, we verify the feasibility and effectiveness of the framework through experiments.

최근 각광받고 있는 연구분야 중 하나인 Internet of Things (IoT)은 사물들이 네트워크 상에 연결되어 있는 있는 컴퓨팅 환경으로, 이 환경을 구성하는 여러 IoT 디바이스들이 협업을 통해 사용자에게 유용한 기능을 제공할 수 있는 장점이 있다. IoT 디바이스의 제한된 배터리 수명, 이동성과 같은 동적인 특성으로 인해 IoT 디바이스의 상태는 계속해서 변하게 되며, 이로 인해 IoT 디바이스를 관리하는 데에 어려움이 있다. 본 논문에서는 IoT 디바이스의 동적인 특성에 의한 IoT 디바이스 관리 문제를 도출하고 이를 해결하기 위한 디바이스 관리 프레임워크를 제안한다. 그리고, 디바이스 검색, 디바이스 상태 확인, 디바이스 선택 및 연결, 그리고 디바이스 교체를 포함한 네 가지의 기법을 제시한다. 또한 제시된 기법들을 기반으로 디바이스 관리 프레임워크를 구현하고 실험을 통하여 제안한 기법들의 실효성을 검증한다.
