초록/요약
In this paper, we present the OSGi based home network system in ubiquitous environment that controls the room appliances providing user mobility. The current home network technology (such as Havi, Jini, UPnP) is limited to static local area. However, we propose ubiquitous concepts of home network system of user mobility in context-aware computing. It is called as UHNE-CG (Ubiquitous Home Network Environment) which can overcome weak points of ubiquity and computational power of Home network. UHNE-CG controls home appliances according to context information. It also gives grid computational power into home environment. This UHNE-CG system is executed on OSGi framework which has several benefits of system extensibility. The services are packed as OSGi bundles such as context bundle, grid bundle. Context bundle provides context concepts to home network environment. Grid bundle gives ability of computational power. Context bundle is comprised of 4 parts. First of them is context detector that detects user entering/leaving and used device. Next, it is person locator which provides user mobility from previous location. The third, it is context analyzer that provides same environment of user at anyplace. At last, home manager matches and executes proper home appliances according to context information. We also consider computational power into home territory. UHNE-CG system enables this functionality with grid computing which is performed by grid bundle. Grid bundle consists of 4 parts. There is grid proxy manager for grid authorization, job manager for computational job, MDS manager for searching grid resource and gridFTP manager for file transferring in grid environment. As a result, in UHNE-CG, context-aware characteristic gives merits such as adaptability and intelligent environment. Moreover it gives the capabilities: autonomous execution in grid environment and computational power. Context and grid service bundle development can also have benefits of remote functionality and extensibility that are provided by OSGi.
