We have studied the methods to connect homes with a digital network and apply home automation to education. We presented the possibility of integrated education where public education at school can be extended to home. The hardwares related with home automation are continuously in development. We have demonstrated the materials appropriate for the levels of individual students with home network information, and studied methods of education.

In this parer, a novel architecture for Home gateway is Proposed. In home network system, there exist many different kinds of data types, like audio, video, and control information. And the communication is over multiple networks, like bluetooth, wireless LAN, USB, IEEE1394, and Power Line Communication (PLC). The hardware architecture of the Home gateway presented in this paper is based on ISO/1EC JTC 1/sc 2S/WG 1(1,2). The architecture proposed in this paper takes into account the characteristics of home network environment, so the Packets in the home network system can be processed very efficiently.

For activating home network, the security service is positively necessary and especially the access control supports secure home network services and differentiated services. But, the existing security technology for home network seldom consider access control or has a architecture to be dependent on specific middleware. Therefore, in this paper we propose a scheme to support integrated access control in home network to use XACML, access control standard of next generation, to have compatability and extensibility and we design and implement XACML access control system based on this. we also had m access control experiment about various policy to connect developed XACML access control system with the UPnP proxy based on OSGi in order to verify compatability with existing home network system.

As today's home-network market grows related researches had been increased and with different interfaces of these products of course there is lack of compatibility between these systems. So we need some extensionable managing system which integrates and manages these systems. In this paper, we designed framework that integrates and manages network system and also implemented Home Gateway using JMX on Sensor-network environment. It may manage each target with modulization and through the connection interface we make allowance compatibility and extensionability between existing systems. Through this researches, we implemented the Home-network integrated managing system which can manage and monitor with PDA or RDP(remote desktop PC).

A new method to control a remote robot with PDA and wireless network is presented. The needs of remote control systems using a home network environments are increased in these days. To solve the shortage of IP address in network, authorized TCP/IP and unauthorized TCP/IP address are used. The unauthorized TCP/IP is obtained by using MAC Address in the system and Network Layer. The model in the system is similar to Sever&Client in structure. Using this system, it is very easy to combine one network device with other network system. A robot system and PDA are used to show the effectiveness of the control system in home network environments.

This paper presents requirements of home network protocol for home netowkr system. Home network protocol is designed to satisfy the above requirements on the assumption that it has to be implemented by software on the microprocessors generally used in household appliances. And, we execute a qualitative comparison to other protocols such as CEBus, LonWorks and LnCP.

We propose and develop Home Security robot system based on Sensor Network (HSSN) configured by sensor nodes including radio frequency (RF), ultrasonic, temperature, light and sound sensors. Our system can acknowledge security alarm events that are acquired by sensor nodes and relayed in the hop-by-hop transmission way. There are sensor network, Home Security Mobile Robot (HSMR) and Home Server(HS) in this system. In the experimental results of this system, we presented that our system has more enhanced performance of response to emergency context and more speedy and accurate path planning to target position for arriving an alarm zone with obstacle avoidance and acquiring the context-aware information.

In this paper, we designed and implemented home gateway system for remote control of home appliances and devices using cellular phone. The system communicate home devices through Zigbee protocol and home server based on Linux operating system communicate cellular phone through external networks. We expect that the system apply various fields as home automations, home network, smart offices, and ubiquious environments.

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.

The advances in the digital communication and network technology, Internet technology and the proliferation of smart appliances in home, have dramatically increased the need for a high speed/high quality home network. As consumer electronic devices and computing devices are increasing in the home network, it is obvious that the data traffic of home network increases as well. Various home network devices want to access Internet servers to get multimedia contents. Therefore, we introduce TLC(Telephone Line Carrier) system for networked digital consumer electronic appliances within a house using Ethernet or wire/wireless technology. In the future home network environment, the primary purposes of the smart home network based TLC are to create low-cost, easily deployable, high performance, and wide coverage throughout the home. In this paper, the channel capacity of telephone line communication system is evaluated and compared as a function of transmission power, number of OFDM carrier, channel loss, and noise loss for smart home network.
