In ubiquitous home where a variety of home devices and sensors are inter-connected, various services can be provided through wired and wireless networks invisibly. The convenience of users can be maximized by using intelligent and adaptive interoperability technologies in the home. In this paper, we present the core techniques including context-awareness, management of context information from various sensors, an inference module using JESS and so on. Also we design the ubiquitous home service systems based on context-awareness.

Smart Home or Home Network technology is one that continuously creates added value, making a better life. This paper designed and developed a smart home control system using smart phone. This proposed smart home system consists of home server control system, remote smart application system and home node structure. Home node structure, in detail, is composed of intrusion detection, gas leakage or gas valve control, door lock, automatic curtain, ventilation control and On/Off control modules and these modules are controlled at home server. Home server makes it easy to control home automatic control system anytime, anywhere as it provides remote interface that enables control via smartphone and user interface in itself.

본 논문에서는 유비쿼터스 사회로의 출발점인 '홈네트워크'를 구축하는데 있어서 가장 기본이 되는 홈서버와 센서간의 인증을 구현하는데 목적을 두었다. 홈 서버와 센서간에 통신을 할 때 해쉬함수 중 MD5를 통해 그룹키를 생성하고 그룹키를 조도센서에 적용하여 서버와 센서간의 인증이 이뤄지는 것을 확인하였다.

본 논문에서는 유비쿼터스 서비스간의 변환을 통하여 유비쿼터스 서비스 통합 및 제어를 위한 유비쿼터스 홈(u-Home) 서비스 통합 모델을 제시하고 있으며, 이러한 유비쿼터스 서비스간의 변환은 SOA(Service-oriented architecture)을 기반으로 하는 서비스 변환 게이트웨이 엔진을 이용하여 이루어진다. 이 SOA기반의 서비스 변환 게이트웨이 엔진을 이용한 u-Home 서비스 통합 모델은 유비쿼터스 서비스들을 웹 서비스 형태의 서비스로 변환하고, 이를 이용해 유비쿼터스 서비스들을 일괄되게 제어할 수 있게 하여, u-Home 내에서의 유비쿼터스 서비스 통합을 이루도록 하기 위한 유비쿼터스 서비스 모델이다.

In multimedia service of Ubiquitous Home Environment(UHE), the requirements such as intelligent service that is executed automatically without direct order of user and fitted service compatible for each user and comfortable of user, interoperability of multimedia contents between incompatible devices will increase. Multimedia protection and management, authentication and authority administration methods that are suitable for above demands are also required. In this paper, we suggest authentication method suited for UHE and propose user oriented multimedia service(UHMS: Ubiquitous Home Multimedia Service) that provides the interoperability of multimedia between incompatible devices, conducts intelligently the context information (preference information, device information etc.) using sensor module and home server, provides and secure services.

The purpose of this study was to propose ubiquitous housing environment based on older residents' needs for ubiquitous(UT) home services. For this purpose, at the previous study which was the first stage of this study, UT home services by each elderly household based on spouse, income level, and health status were identified and this study finally proposed UT home services by each elderly household type according to residents' level of needs for UT home services. One to one interview with a structured survey questionnaire and illustration was implemented and 204 older residents who were composed of one of six elderly household types were responded. Among 6 types of elderly households, type 2 and 6 were the groups which had higher needs for various kinds of UT home services. Economic status and their health status were the key factors to determine their needs for UT home services. Type 4 and 7 were the groups to express their lower needs for UT home services due to their lower income level and good health condition. Ultimately, two floor plans for type 4 and 5 elderly households were developed to show applicable UT home services in each room of the house.
