Abstract

A home network provides users with a variety of information services. The kind and quality of the services can be substantially enhanced by utilizing a variety of data from sensors. However, home networks currently limit their potential by focusing on providing multimedia services rather than services utilizing sensor data. Outdoor electronics are frequently made in a form that emphasizes only certain limited functions in contrast to home appliances. Thus, sensors with one or two functions rather than many can be used in outdoor systems and their use will be more economical than using sensor nodes indoors with more complex home appliances. In this study, we chose to work with motion sensors as they have many potential uses, and we selected a parking lot control system with to use the motion sensors. This parking lot control system was implemented and applied as part of a home network. For this purpose, we defined and implemented a protocol to manage the network in a ubiquitous sensor network environment for the wireless home network in this study. Although a network management system in a Ubiquitous Sensor Network (USN) related to this study is being advanced for other projects, the protocol interface and message system have not yet been clearly defined for use in a general purpose network or in an extension into heterogeneous kinds of networks, communication support, etc. Therefore, USN network management should be conducted for management of faults, composition, power, and applications. To verify the performance of the protocol interface designed in this study, we designed and implemented the necessary units (sensor nodes, sensor gateway, and server) for each network section and, with them, proved the validity of this study.

홈 네트워크는 사용자에게 많은 정보서비스를 제공하여 준다. 특히, 다양한 센서 데이터를 활용함으로써 그 서비스의 종류와 질을 풍부하게 한다. 하지만 홈네트워크는 현재 멀티미디어 서비스에 집중함으로써 그 서비스의 활용폭을 스스로 제한하고 있는 실정이다. 특히 댁내 통신망에 집중함으로써 실내의 여러 가전기기를 제어하는 데는 많은 성과를 얻고 있으나 실외의 여러 기기를 제어하는 데는 큰 성과가 나오지 않고 있다. 실외의 여러 기기는 실내의 가전기기와 다르게 특정 기능을 강조하는 형태로 구성되는 경우가 많기 때문에 여러 기능을 가진 센서보다는 한 두가지 기능을 가진 센서를 활용하여 시스템을 구성하면 되기 때문에 실내에서 센서 노드를 사용하는 것보다 훨씬 경제성도 높다고 할 수 있다. 본 논문에서는 현재 가장 많은 사용 목적을 가진 여러 가지 기능 중 동작 센서를 선택하여 이를 활용할 시스템으로 주차장 관리 시스템을 선택하여 이를 홈 네트워크에 접목하여 구현하여 보았다.
