본 논문에서는 적외선을 기반으로 하는 가정용 정보가전기기들을 실내 또는 실외에서 원격으로 제어 및 감시할 수 있는 가정용 정보가전기기 제어 시스템을 구현하였다. 무선 인터넷 접속이 가능한 PDA에 본 논문에서 구현한 클라이언트 응용 프로세서를 동작시키고 가정용 홈 서버에는 정보가전기기를 제어하기 위한 서버 응용 프로세서 및 필요한 제어용 하드웨어 장치들을 부착하였다. 클라이언트 및 서버의 구현구조, 응용 프로세스 간 제어 메시지 등 구현의 세부 내용을 기술하였다. 본 구현의 세부 내용은 차세대 인터넷 프로토콜(IPv6)을 지원할 수 있도록 쉽게 수정 보완될 수 있으므로 IPv6용 가정용 정보가전기기 제어시스템의 개발에 쉽게 적용될 수 있다.

인터넷 정보 가전(IA: Internet Appliances)은 매우 복합적이고 다양한 제품과 기술로 구성되어 있지만, 간단하게 정의하자면 유무선 정보통신망에 연결되어 데이터 송수신이 가능한 디지털 TV, 인터넷 냉장고, DVD, 디지털 비디오 등과 같은 차세대 네트워크 가전제품을 말한다[l]. 이러한 인터넷 정보 가전에 있어서 Home PNA, PLC, IEEE1394, 무선 랜, Home RF, Bluetooth 등 다양한 기술과 규격이 홈 네트워크로 제시되어 있지만 이를 도입하기엔 부담이 큰 가전기기들이 대부분인 것이 현실이다. 따라서 본 연구에서는 홈 서버의 직렬 포트에 무선 모뎀을 장착해서 이동 로봇을 원격 제어하는 시스템을 설계 구현함으로써 하드웨어 및 소프트웨어적인 비용이 저렴한 인터넷 정보 가전용 이동 로봇 시스템의 구현 가능성을 제시한다.

People want to control various facilities regardless location in ubiquitous era. Therefore we have a various devices embedded wireless functions. In this paper we implement a control program in a PDA that used Wireless LAN among wireless protocols. The objectives of this paper are: The first, to make a control program in server and a wireless client (PDA) using WLAN. The second, to implement smart home model. The third, to propose useful functions in home controls.

Upon the changes of human life style due to the distribution of ultra-high speed internet services and the development of high-tech information equipment, the idea of necessity fer home networking has been widely accepted. Thus, "embedded ethernet module" was designed in this paper for the stabilization of home networking by using 8051 MCU, Hardwired TCP/IP (W3150A). By executing remote software on established simple web-server on the target machine, controlling electric equipment became available elsewhere. With this module, establishing a low-cost home automations system would become possible in a ubiquitous society.

Home network providers have many worries about providing home network services with an expandable, reliable, flexible and low-cost structure according to the expanding market environment. The existing client-server system has various problems such as complexity and high costs in providing home network services. In this paper we propose the P2P-SIP structure. P2P communication terminal supporting access of distributed resources provides functions which the existing SIP-based network devices have. Because diverse terminals in a home network access through networks, also, partitioning network domains with home gateways to manage, and applying the network-based PMIPv6(Proxy Mobile IPv6) technology considering mobility of terminals would help to have a more efficient home network structure. Especially, the proposed P2P-SIP structure proves itself as a very efficient structure to have an outstanding expandability among different home networks in a region, and to reduce maintenance costs.

In this paper, we implemented a home IoT system based on MQTT protocol. In this system, data are collected from sensors in real time and transmitted to the server system. Based on collected data, home devices could be controlled automatically or manually. By using the MQTT protocol, we were able to see the data values of sensors collected in real time according to the topic setting. We implemented a system that automatically sets up home devices based on topic data, and it worked. The system is expected to be useful in applications that require monitoring and tracking of data in real time.

The internet of things(: IoT) which could produce new information as well as service through connecting small devices with internet interface becomes reality and could be utilized in home, office and plant. Especially the IoT can provide our home for safety, security, convenience, and power saving since all devices form a small internet. This paper proposes an IoT prototype for home with Raspberry Pi which has various sensors and monitors environment. This Raspberry Pi sensor node is small and inexpensive but can provide powerful service. The implemented node goes beyond simple role of sensor node and features a kind of sensor web node which performs various functions to outer network. So the proposed IoT prototype can provide flexibility as well as extensibility since it does not need expensive server.

This paper describes the system that enables users to control the home electronic equipment using mobile phone. The home network industry is setting in network period that grow rapidly and get many interests. And, it is real condition that hailing of existed system is rising too. This paper developed system to make use of mobile phone regarding this and control boiler temperature in home to remote. This paper that serve this used skill of mobile programming, mobile Brew, RF radio communication, etc. for communication with server in an experiment. This paper presented another method that use RF radio communication and mobile device in home automation construction. The result of this paper will be expected to be able to contribute little in development of home network industry.

Intelligence Home and Home Automation, which attracted attention before Smart Home, caused inconvenience to users by focusing on applying cutting-edge technologies to homes, and failed to popularize them due to lack of unemployment efficiency. However, with the 4th Industrial Revolution, various services using technologies related to big data, artificial intelligence, and the Internet of Things are increasing, and the rate of smart home services that operate, manage, and automate products at home is gradually increasing. In line with this trend, this paper implements a program app that can connect, manipulate, and manage products using MQTT server, Django web framework, and WIFI communication module.

This paper describes the design and implementation of architecture for convergence of home network services and data broadcasting services based on UMB and ACAP middleware; the one is used for interoperability of home networked devices, and the other for data broadcasting services. The proposed architecture provides TV-centric user interface capable of managing home network services and data broadcasting services together using a remote controller and TV sets TV applying Java TV Xlet interface and HAVi user interface for home network services like data broadcasting services. Besides, we define the service proxy for accessing home network services in a set-top box and the service broker for providing data related to home network services in a home server. Finally, the application manager in ACAP middleware manages the lifecycle of home network services through service events from the service proxy to the application manager.
