New paradigm of the 21st is 'Ubiquitous'. And great changes arises from the digital environment and technology. Also, our living environments are changing very rapidly. Because of rapid developments, we didn't have enough time to examine our current situation. So we had to look around the current living spaces. The main purpose of this research was to know about the home network service and environmental context in our living spaces and to explore the outlook in the forseeable future. To search them, four recent digital home exhibition houses were examined. The findings showed that many kinds of common network systems were suggested and were acted in limited spaces. And when we examined the environmental context, we found most of the instruments were installed fixed ones or integrated information appliances. Therefore, the plan of digital home needs to consider environmental context and the combination of residents and living spaces.

Recently, various ubiquitous networking services are developed and implemented for easy living. In general, new ubiquitous networking services require the new infrastructure including equipments and devices. However, it is difficult to replace existing infrastructure and devices with new ones in the home or office because of cost and maintenance problems. In this paper, we developed small-size web based RF wireless communication systems for sensor network applications. The designed RF systems are implemented using commercial system on a chip (SoC) on existing infrastructure and devices. The developed systems are tested for light control and temperature sensing and they are applied to sensor network training courses for students and engineer as well as various practical applications.

As various mobile technologies, sensor technologies, remote control and infrastructure are developing and expectations on quality of life are increasing, a lot of researches and developments on home network technologies and services are actively on going. Until now, we focused on how to provide users with high-level home network services, while not many researches on home network security for guaranteeing safety are progressing, So, in this paper, we propose an access control model for home network that provides various users with home network services up one's characteristics and features, and protects home network systems from illegal accesses or intrusions.

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.

A home network is a typical ubiquitous computing network that consists of various consumer devices and service environments. Home networks are requiring increasingly more complicated services, such as multimedia home theater and the monitoring and controlling of heterogeneous devices. Accordingly, a mutually connecting mechanism is needed among heterogeneous devices and services redundant. The current paper presents a Multimedia Room Bridge Adapter (MRBA) system that is designed to manage heterogeneous devices and support various services. In addition, a hardware and software prototype is implemented based on the proposed architecture.

The demand for wireless technology in home automation systems has recently been increasing due to several advantages such as installation cost reduction, easy placement, easy extension, aesthetic benefits, and mobile device connectivity. Among the many wireless technologies, ZigBee is one of the most useful for home automation; a wireless home networking system can be configured using ZigBee alone. Compatibility with conventional home networking systems that are based on wired media, however, is not supported. KNX is a mature protocol for wired media that is recognized as an international standard. This paper proposes a KNX-ZigBee gateway to interface between KNX and ZigBee systems and thereby enable integration of wired and wireless home automation systems.

The home network environment can be defined as a network environment, connecting digital home devices such as computer systems, digital appliances, and mobile devices. In this kind of home network environments, there will be numerous local/remote interactions to monitor and control the home network devices and the home gateway. Such an environment may result in communication bottleneck. By applying the mobile agents that can migrate among the computing devices autonomously and work on behalf of the user, remote interactions and network traffics can be reduced enormously. The mobile agent authentication is necessary to apply mobile agent concept to the home network environments, as a prerequisite technology for authorization or access control to the home network devices and resources. The existing mobile agent systems have mainly used the public key based authentication scheme, which is not suitable to the home network environments, composed of digital devices of limited computation capability. In this paper, we propose a shared key based mobile agent authentication scheme for single home domain and expand the scheme to multiple domain environments with the public key based authentication scheme. Application of the shared key encryption scheme to the single domain mobile agent authentication enables to authenticate the mobile agent with less overhead than the public key based authentication scheme.

This study is to reconstruct the user-oriented e-government service based on home network infrastructure using ubiquitous computing technology. Until now, 31 e-government roadmap tasks have been promoted as main projects of e-government. This study explores what should be respective priorities for the suppliers and users of e-government if the services are provided in linkage with home network infrastructure. The result of survey showed us that the efficiency of administration and the improvement of the civil service, including citizens' online participation should be priorities. In order to reinforce home network infrastructure in implementing u-government, the government, at first, has to relax regulation, support businesses to develop related technologies, and construct safe infrastructure for citizens to use e-government services. Second, businesses should develop home network technologies that include various contents and construct home network systems that citizens can use easily. Third, citizens should have interests and participate in the government policies for home network services. Particularly, this study aims to suggest policies that consider positions of both the suppliers and users of e-government so that home network-based e-government can be implemented in the future.

The specification of the Home Evolved NodeB (Home-eNB), which is a small base station designed for use in residential or small business environment, is currently ongoing in 3GPP LTE (Long Term Evolution) systems. One of the key requirements for its feasibility in the LTE system is the mobility management in the deployment of the numerous Home-eNBs and other 3GPP network. In this paper, we overview the characteristic of Home-eNB and also describe the mobility management issues and the related approaches in 3GPP LTE based Home-eNB systems.
