초고속 통신망과 인터넷정보가전기기의 개발로 인해 사이버 아파트를 중심으로 홈네트워크 환경을 빠르게 갖추게 되었다. 홈 네트워크 환경은 가정내의 수많은 가전기기들이 네트워크로 연결되어 윤택한 가정 내의 환경을 제공해 준다. 그러므로, 최근 네트워크로 연결된 인터넷 정보가전의 등장으로 인하여 해킹, 오동작 및 고장과 홈 오토메이션에서의 방범, 화재, 침입 등을 통합 관리하는 서비스 요구가 증대되고 있다. 본 논문에서는 홈 네트워크 정보가전기기 환경에서의 통합위기관리 서비스 모델을 설계 제안한다. 즉, 정보가전 위기관리 서비스를 분류하고 XML로 위기관리 메시지를 정의한다. 위기상황이 발생된 메시지는 무선단말기인 PDA나 휴대폰 또는 관련기관에 통보되어 처리된다.

Deploying advanced home networking technologies and modern home-networked devices in residential environments provides a playground for new home applications and services. Because home multimedia entertainment is among the most essential home applications, this paper presents an appealing home media content sharing scenario: home-networked devices can discover neighboring devices and share local media content, as well as enormous amounts of Internet media content in a convenient and networked manner. This ideal scenario differs from traditional usages that merely offer local media content and require tedious manual operations of connection setup and file transfer among various devices. To achieve this goal, this study proposes a proxy gateway architecture for home multimedia content distribution. The proposed architecture integrates several functional mechanisms, including UPnP-based device discovery, home gateway, Internet media provision, and in-home media content delivery. This design addresses several inherent limitations of device heterogeneity and network interoperability on home and public networks, and allows diverse home-networked devices to play media content in an identical and networked manner. Prototypical implementation of the proposed proxy gateway architecture develops a proof-of-concept software, integrating a BitTorrent peer-to-peer client, a UPnP protocol stack, and a UPnP AV media server, as well as media distribution and management components on the OSGi home gateway platform. Practical demonstration shows the proposed design and scenario realization, offering users an unlimited volume of media content for home multimedia entertainment.

홈 서비스 네트워크 시스템은 실용적이면서 프로엑티브한 결함 관리를 통한 고가용도 서비스를 필요로 한다. 하지만, 홈 서비스 시스템의 복잡도가 증가하면서 고가용도 요구사항을 만족하기 위한 서비스를 제공하는 것은 더욱 어려워졌다. 더욱이, 사용자는 시스템 결함 관리와 같은 복잡한 시스템 관리를 직접 하는걸 원하지 않는다. 그러므로 홈 네트워크로 연결된 장치 또는 가전제품으로 구성된 통합 시스템의 고가용도 요구사항을 만족하면서 사람의 개입을 최소화할 수 있는 자가 관리 기능 및 원격 결함 관리 능력을 홈 서비스 시스템은 갖춰야 한다. 따라서 본 논문에서는 흠 서비스 네트워크 시스템의 가용도를 향상시키면서 관리 비용을 최소화할 수 있는 원격 자기 관리 메커니즘을 탑재한 오토노믹 자기치유 유틸리티를 설계 및 개발한다.

This paper describes design and implementation of home network control protocol for networked home appliances. The proposed network protocol has four-layered protocol structure and device-modem interface structure for the flexibility of modems based on power line communication. The standard message set is specified to guarantee the interoperability between various home appliances The proposed protocol can be easily implemented because it has minimum network overhead.

Home-network gateway always powered on, while network data is not transferred. And the Power consumption of networked electric devices are greatly increased, to support higher speed data transfer. To reduce the power consumption of networked electric devices, some ideas were proposed. Such as ALR, Proxying, Subset-PHY. In this paper we propose a scheme to reduce power consumption of Home-Network Gateway. Proposed Home-network Gateway architecture consumes less than 1W in passive standby mode.

The networked home is connected to the external world using a high speed network. The devices inside the house are connected using a wired and wireless network. Acquiring the user data is an essential step for designing the user interface in user centered design. In networked home, the numbers of use cases are exponentially increased because connected use cases are considered. Because the user data for networked home are too complicated, they are acquired and analyzed by a structured methodology. We surveyed 40 people to acquire the context data home and analyzed by 5W1H (Who, Where, What, When, Why, How). We established a framework for the user data using tasks, user, time, space, objects and environment. The data for home context was structured by our framework. This framework makes simple the home context and is helpful for user interface design in home network.

This paper presents a systematic method of probing channel characteristics and communication reliabilities of home power line communication network applied to the Internet accessed control of home appliances. The effects of the three performance deteriorating factors, i.e., additive noise, channel attenuation, and intersymbol interference, can be systematically measured by applying the channel probing waveform in the frequency range from 100㎑ to 450㎑. Probability of bit error is derived with the probed channel parameters of the signal attenuation, noise and signal-to-interference ratio read in the frequency domain. The agreement between the derived probability of bit ewer and the measured probability of bit error support the validity of the proposed approach of probing home power line channel characteristics. The experimental results performed with the constructed test-bed applying the Proposed channel probing method and the operation reliability measurement of the overall networked system also support the feasibility of commercially deploying the PLC modem installed home appliances and their services for the Internet accessed home automation in densely populated residential apartment complexes.
