In this paper, we propose a home-networking service using mobile phone and ZigBee module. Recently, ZigBee is widely used for various applications due to its characteristics. Especially, it is generally adopted for home network services. We propose a new home network service model using mobile phones. In the proposed architecture, the mobile phones are connected to conventional home network appliances using ZigBee dongle. Also, several servers are implemented for service management. We implement the whole components of the proposed architecture and show the validity of the proposed method. With the proposed service structure, it is expected to provide various ubiquitous services for the user.

Network industry is complex combined with various fields of industry, such as communication, broadcast, construction, and home appliances. Moreover, it's fairly lucrative since the growth industry makes lots of added values, interacting with the others.The network industry, usually called 'Ubiquitous', connects some home appliances and makes an integrated system that you can use them with whenever and wherever. A demand for network security, however, has skyrocketed due to the relatively low safety. It's been expected that the market of home security is going to be grown up nearly 30 percent every year. Recently, analog surveilance cameras have been replaced with digital ones, and they will be providing stronger security services taking advantage of mutual interaction with related industies. In this paper, a mobile monitoring system for home security is proposed, which makes it possible to supervise all home appliances wherever you're, using the conventional wired/wireless network infra.

Nowadays great changes arises from the digital environment and technology. And Also, our living environment are changes very rapidly. The purpose of this study was to analyze the characteristics and trends of future housing reference to ubiquitous housing cases in U.S.A, Japan and Korea. From these cases, reorganized ubiquitous-apartment elements are suitable to our housing environment. To search them, it is investigated to 4 ubiquitous housing examples, such as Aware Home, Toyota's PAPI, samsung raemian's housing gallery and GS E&C's apartment. In this study, we could get types and characteristics and planning elements of ubiquitous housings. The findings showed that many kinds of common network systems were suggested and were acted in limited spaces. In conclusion, it was considered as the one of the most suitable future housing type that had a special feature of the demands of residence and life with free accessibility of information and data. Especially, it is necessary to prepare for coming aging society.

It is essential to investigate the structure and the main characteristic of Home USN (Ubiquitous Sensor Network) technologies in built ubiquitous environment while designing future residential space. For this study, three different housing types have been selected to implement ubiquitous technologies for residential space; those are regular, elderly, and single residence units. It is certain that efficiency of ubiquitous home design is improved if main components of each specific housing type are analyzed precisely in digital way and design models are prepared accordingly. Ubiquitous technology, in conclusion, has to be applied not on)r with systematical mechanism or electronic setting but in human-centered atmosphere as well, keeping with deep consideration for bio-housing service factors in eco-friendly surrounding; we call this Ubiquitous Humanism.

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.

The aim of this research is to study and develop enabling technologies for home healthcare device with ubiquitous network. The motivation of this paper is to enable healthcare in home, to development the device for smart home health care. To achieve the aim, we must develop the prototype platform based on home gateways, distributed context user interface based on UPnP and support for information sharing with high speed power line communication and mobile infra-structures. And IPv6 is the base technology of this platform. In this paper, we concern that physical health, mental health and medical emergencies is all of home healthcare. With the smart device, we evaluate the connectivity, automatic information extraction and private data exchange and event driven message. The result of this paper is demonstration of smart device for ubiquitous communication in a healthcare application such as patient monitoring device and several information services. In conclusion, home healthcare will support more healthy and easy living for a human.

This study is intended to forecast changes in Ubiquitous technology-based residential environment since the digital revolution so as to suggest the direction of furniture design in the near future. Among Ubiquitous technologies, the intelligent digital technology applied to a residential environment is defined as "Smart Digital Technology." Ministry of Commerce, Industry and Energy named the residential environment where such technology is applied "Smart Home." Smart Home is strategically creating intelligent residential environment where interactivity is made between human, furniture and residential environment, based on home automation, home network and intelligent sensor technology. Smart furniture is based on strategic characteristics of smart home. Its convergence with IT equipments is being made. Largely, smart furniture has three characteristics as below: First, smart furniture provides users with information on home management, health management, education and fashion. not just functioning as storage space. Second, smart furniture that is a new lifestyle pattern will suggest a new aesthetic standard based on unsettled shapes and innovative structure. Finally, it gives convenience to users intelligently. Namely, smart furniture, "intelligent informative furniture", will be suggested as a new paradigm.

최근 들어 언제 어디서나 컴퓨팅이 가능한 유비쿼터스 컴퓨팅(Ubiquitous Computing) 사회가 되면서 개인의 컴퓨팅 환경 의존도가 증가되었고, 따라서 사이버공격으로 인한 개인생활의 위협도 증가할 수밖에 없게 되었다. 더욱이 향후에는 원격진료와 같이 개인의 생명과 직결된 유비쿼터스 서비스가 활성화될 것이므로 사이버공격으로 인해 재산뿐 아니라 생명까지 위험에 처하는 경우가 늘어나게 될 것이다. 이로 인해 유비쿼터스 환경에 적합한 홈네트워크 보안(Home Network Secutity)의 중요성이 부각되게 되었다. 본 논문에서는 안전한 U-홈네트워크(Ubiquitous-Home Network) 구축에 필요한 기술들을 유 무선 기준으로 구분하고, U-홈네트워크 환경에서 발생할 수 있는 다양한 침해유형을 분석하여, 이를 막아낼 수 있는 대응방안을 수립하고, 안전한 U-홈네트워크 구축을 위해 필요한 기존의 보안요구사항들을 살펴본 후에 U-홈네트워크에 적합한 추가적 보안사항을 제안하고자 한다.
