Recently, public home have used a more than two computer connected with network, and several home appliances using independently with internet or network are developing to be related closely with the network. Therefore, the home utilized for a simple terminal of the global network in the past is being expanded to another part of the sub network. For a variety of connecting home-area protocols with the existing existing network, we require a new Residential Gateway(RG) that does not only make the home-area network operating in the sub network but also connects to the external network. In this paper, RG has intrinsic limits against flexible service due to IP address assignment and hardware capacity. In order to solve this problem in the RG, we propose a Management Server(MS). The MS that offers the integrated managements and control services for a variety of devices connected the RG in the home-area. It can not only solve the dynamic IP address assigning problem but also assigns private IP addresses to the home network devices through the Network Address Translation(NAT). It also provides somewhat useful functions for the home network and the RG for other additional services. <중략> The MS is using a SNMP protocol for managing the RG in the domain, a polling method of the MS and the RG compose a sequence polling method, a polling method using a multi-process and a multi-thread. In this paper, we introduce a problem with polling method separately, show a polling method between the MS and the RG using a multi-thread.

홈 네트워크의 문제점인 IP 부족 문제와 부가 서비스(디지털 컨텐츠의 지능형 서비스, 서비스 번들 지원 등) 제공의 한계성을 극복하기 위해 Service Server for Residential Gateway(SSRG)를 제안한다. SSRG는 단독주택뿐만 아니라 대규모 아파트 단지 혹은 주택단지에 개별적으로 설치된 RG를 통합 관리하는 서버로서 홈 네트워크 및 내부 네트워크에 로컬 IP를 부여하고 RG와 SSRG를 NAT(Network Address Translator)를 통하여 제어함으로써 P의 문제를 해결함과 동시에 각 홈 네트워크와 RG의 기능을 확대하고 보다 많은 부가 서비스를 제공할 수 있도록 구현하였다. 제안된 SSRG는 가정 내에 보다 확장된 서비스와 기기 관리를 위한 통로 제공, RG 및 각종 기기들의 소프트웨어 업그레이드 및 기기 상태점검이 가능하고, 또한 사설 IP 상에서도 기기들을 외부에서 액세스 할 수 있고 각종 서버를 하나의 단지 혹은 논리적으로 구분되는 하나의 서브 넷에 두게 됨으로써 관리 및 향후 보수가 용이한 장점이 있다.

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.

Recently, energy resource management is a major concern around the world. Energy management activities minimize environmental impacts of the energy production. This paper presents design and prototyping of a home electric energy monitoring system that provides residential consumers with real time information about their electricity use. The developed system is composed of an in-house sensing system and a server system. The in-home sensing system is a set of wireless smart plug which have an AC power socket, a relay to switch the socket ON/OFF, a CT sensor to sense current of load appliance and a Kmote. The Kmote is a wireless communication interface based on TinyOS. Each sensing node sends its detection signal to a home gateway via wireless link. The home gateway stores the received signals into a remote database. The server system is composed of a database server and a web server, which provides web-based monitoring system to residential consumers. We analyzed and presented energy consumption data from electrical appliances for 3 months in home. The experimental results show the promising possibilities to estimate the energy consumption patterns and the current status.

In the paper, the Management Server (MS) is designed and developed in order to overcome 1 imitations in the Residential Gateway (RG). The Proposed MS is composed of the Network Management System(NMS), Home Automation System(HAS), Persistent Data Management(PDM). The developed MS is a dedicated server which manages both individual RG and internet home appliances implemented at a home-network environments.

특정 소수에서 사용되던 인터넷이 불특정 다수의 사람들에게 장소에 구애받지 않고 점차 확산 되어 오면서 사용자의 요구 및 그 시장 역시 기하급수적으로 증가해왔다. 처음에는 단순히 접속 속도 향상에서부터 현재는 무선이라는 접속방법의 발전까지 사용자의 편의를 위한 기술 개발 노력은 결실을 맺고 있다고 해도 과언이 아니다. 최근에는 댁내까지 서비스되는 PC 중심의 인터넷 기술뿐만 아니라 다른 가전기기를 통한 통신 및 가전기기의 제어 및 모니터링 등 좀더 사용자 편리성을 강조한 삶을 영위하고자 하는 욕구가 점차 증가하고 있다.(중략)

The port space can be considered to be the space in which the characteristics of the port city are best expressed. Also, since it acts as a representative gateway along with the airport, it can have a direct impact on the image of the region and country. However, the harbor hinterland has been a refuge during the war in the past, and it has been concentrating on development related to the port industry; hence, it has a poorer residential environment. Therefore, in this study, in order to ensure equal development in space and equal access to basic urban services, urban design directions were suggested for the harbor hinterland based on the concept of an inclusive city'. To this end, through factor analysis, urban planning elements that can be applied to urban design were derived, and through PLS(Partial Least Square)regression analysis, based on the opinions of residents and experts, urban design directions for the port hinterland were presented. The study site was Gamcheon Port, one of the Busan Ports in Korea, the hinterland of Gamcheon Port was a high slope, and the residential environment was relatively poor due to the dense concentration of older residential areas.
