As various mobile technologies, sensor technologies, remote control and network 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, home network is just beginning, and we are developing home network services necessary to users, incrementing easiness, however we need to research on the safety of home network system guaranteeing the easiness as the services are going actively. So, in this paper, we propose the access control mechanism for protecting the home network system against indoor/outdoor illegal accesses and unauthorized accesses.

As there have recently been a rapid development in a supercomputer network infrastructure and an increase in the use of wireless terminals such as a PDA and cellular phone, people realize that it is highly required that they develope a various types of application services to integrate wireless network and engage them. On top of that, because current appliances are being converted into digital domestic appliances, and network and such appliances react upon each other, domestic appliances are now evolving to Internet appliances. Thus, people eager to establish a home network, which can offer a various sorts of services to customers because such appliances can share and send the data when such appliances are connected to power lines, telephone wires, and IEEE1394. Along with this, people are also enthusiastically conducting a study on Internet Application, which monitor and control the internet appliances triggered by connecting home network and supercomputer network. This study focuses on designing and developing an integrated wireless home server by effectively integrating wire and wireless network: It can approach and control each internet appliance connected with the home network inside and outside the house. In this study we also test it with an internet appliance simulator.

As home network system begins serving in earnest, the recent fruits of research in home service robot show that the new epoch that human and intelligent robots are living, communicating and interacting together at home, may come true in the near future. In the other hand, it is generally known that the multiagent system, performing distributed process together with other different devices in a home network system, is better than single robot or single home server for adapting themselves to home environment and completing their mission because the characteristic of home environment is 'open'. Therefore, in this paper we suggest the framework model to define agents, which is needed lot the home with a home network system, and the communication protocol architecture between agents. For this, we focus our attention on an agent comprising the set of many agent instances rather than the single intelligent or ability of a robot or home server, and also suggest the way of adaptation for agent systems to their environments and interaction with human in the manner of cooperation and negotiation among agents or agent instances in each agent.

The architecture for RFID-based home network and an intelligent agent for efficiently managing home network are proposed in this paper. The agent consists of six modules-Agent Manager, Data Collector, Execution Controller, Data Storage, Data Queue and User Interface. Agent Manager manages the tasks of modules, and Data Collector collects the data from home appliances through the RFID readersm Execution Controller determines the operations home appliances according to the conditions of the home environment and transfers the operations to the appliances through the RFID readers. Moreover, Data Storage keeps the data which is necessary for the operations of the agent, and Data Queue temporarily stores the data which is collected from home appliances. Lastly, User Interface provides the graphical user interface in which an individual can directly control and monitor the home network. The proposed intelligent agent autonomously learns the circumstances of a home network by analyzing the data about the state of home appliances, and controls home appliances according to the preference of the user. Therefore, the user can live in the best-suited home environment without direct appliance control if he/she performs home networking through the agent.

As various kinds of embedded systems (or devices) become widely available, research on home network middleware which can access and control embedded home appliances are actively being progressed. However, there is a significant problem in applying the home network technology to embedded systems because of their limited storage space and low computing power. In this paper, we present a lightweight middleware for home network on embedded systems. Also, we propose a mechanism for mobility management which adopts the anycast technology.

In this paper, we propose a lightweight mutual authentication protocol for secure and efficient home network service. Lee et al. recently proposed an attribute-base authentication key agreement protocol using public key in home network. Its protocol provided forward secrecy but don't diminish conspicious overhead of operation using ticket. Therefore the proposed protocol provided the security and efficiency using hash function and counter. Also it can provide secure home network service by check consumer electronics control level of users after created session key.

It is rapidly expanding to provide Home Digital Service based on the Home Network System in intelligent apartment. Fortunately, Korea has one of the highest rates of Internet penetration and access in the world. Construction companies used the Home Network system as a strategy of differentiation and it is available to the customers to raise their asset value. Besides, the government has a positive response to accept the new movements to make the digital environment with 'u-Korea (Ubiquitous Korea)' as the slogan. However, the level of providing Home Digital Service is actually at the beginning. The develop the home network industry more effectively, the related industries' cooperation is essential. The purpose of this study is to propose a providing model of Home Network System for the construction company and to make a method to response the fast change of technology development and customer's request at the point of construction companies' view.

TCP typically offers reasonable end-to-end performance to users regardless of the bandwidth and error characteristics of particular network technology, The robustness of TCP has contributed to its success in the internet environment. The role of communications is already well established in the office environment. With the advent of cheap, affordable broadband communications and the increasing complexity of consumer goods, it seems natural to extend the network into homes. In-home networking means a high-speed communication among the digital appliances within a home. Introduction of application over high-speed home network using TCP/IP protocol is increasing. The integrated environment of internet and home network is demanding as well. We have validated TCP model over high speed home network environment, investigated the throughput behavior of TCP over IEEE 1399 home networks, and evaluated a potential solution for high performance of TCP over IEEE 139t home networks. The simulation model has produced several interesting results in the performance of TCP over IEEE 1394 home network.

Home network can be recently communicated with many various devices. but It has complications of the communication of devices. So the methods that can manage the devic integrate them are being developed in home networking And. there are lacks of the consid to provide users with QoS in home networking. Therefore, this paper describes the middlew can integrate home network with policy-based network for the purpose of supporting QoS.

Powerline communication is the data signal which is modulated by carrier frequency through the installed powerline at in-home or office is transmitted and received signals are separated into data signal with using band-pass filter which cent-frequency is carrier frequency. The home gateway, an equipment which works as an gateway for ubiquitous home network, relays all functions of a home network. The home gateway must always be connected in order to provide seamless services. However it gives unfavorable power consumption. Therefore the needs for working in maximum power saving mode while there is no data traffic and for invoking to the normal function when it is necessary. So, in this paper we survey the development of low power PLC modem monitoring of power consumption and breaking abnormal power in the home Network.
