The user authentication and authorization in the current home network system almost works at home and home users, sometimes novice, should manage the system directly. This situation can make much of troubles, sometimes cause some suity problems. Moreover, the system costs high to build up, demands special user knowledge to maintain. In this paper, we propose the user authentication and authorization system based on remote management server to solve the problems, designed and implemented the system. To verify the system performance and function, we built a demo system for information appliances. The results of the test, the authentication and authorization function works well and reliably.

This paper suggests a service model which uses a wireless sensor network in home network environment. The sensor network consists of fixed sensor nodes and user identification nodes which is attached to each user. With the input information of the user preference profile and the collected data from the sensor nodes, the database is constructed as a context information and analyzed by a home server to provide a service that establishes and controls automatically home appliances according to each user's preference. The proposed service model is implemented and tested on a Linux server with MySQL database and sensor nodes on TinyOS.

Today, digital technology can be possible U-city, U-healthcare because network and wireless communication have developed very rapidly and widely. In this paper we implemented embedded server and Zigbee sensor boards. For the development, Implemented home server platform has a Intel PXA255 processor, web server, USB camera and TFT LCD. The other hand, Zigbee sensor boards are attached the AVR microprocessor and the several sensors to get the environment variables.

Recently, as interest in Home networking is increased, research about multimedia clip service is gone. Because of the limit to bandwidth of home network, the problem of server traffic is increased by transferring many multimedia data through Client-Sewer Way for long. The data share network system applied is designed and implemented to solve this problem. P2P is connected directly between clients and exchanges data without going through a sewer. We implemented platform-independent System using Java and applied P2P skill to reduce server traffic.

A Remote Monitoring Server(RMS) server which uses Internet and World Wide Web is constructed for SMD in-line system. Hardware base consists of server computer, virtual SMD in-line system and other computers. Software includes assignment of server, RDBMS and various modules in server home page. Web browser provide production quantity, bad PCB quantity, error number and error message in virtual SMD module, user information in setup module, detailed error information in fault diagnosis module, fault history in fault history module and customer information in customer service management module. These functions of the RMS helps a decrease of non-operation time and a service response as fast as possible.

The enterprise find a solution to the problems such as a reduction of manufacturing period, accurate analysis for customer demand, improvement for customer service and rise of manufacture accomplishment. Internet is a good solution to such problems. Internet offers WWW(World Wide Web), remote control, file transfer and e-mail service. Among the services, WWW takes large portion because of convenient GUI, easy information search and unlimited information registration. Remote Monitoring Server(RMS) system that uses network service is constructed for chip mounter. Hardware base consists of RMS, chip mounter and C/S(Customer Service) server. Software includes DBMS and various modules in server home page. This provide product number, bad product number, trouble code, content and countermeasure in real-time information module, user information in setup module, detailed error information in fault diagnosis module, fault history in fault history module and customer information in customer service management module.

This paper describes an experimental embedded tiny web server system that monitors the processing of manufacture using the Internet. The object of this study is developing of an embedded tiny web server that connects the stand-alone machines in factory to the Internet. Using the World Wide Web (WWW), we proffer user-friendly environments to users. Anyone with a web browser may easily access the processing of manufacture in the factory. Through connecting different network system, our web server extends the private networks to the Internet, the global networks. Our embedded tiny web server is ideal for process control, building and facility management system, factory automation and even home automation.

The home network is the technique to guarantee a safe, economical, socially integrated, and healthy life to the family and it provides domestic safety, instrument control, controllable energy and health monitoring by the connection of the home appliances using wired and wireless networks. A home control system has been developed for managing and controlling home appliances. This paper designs the broadband PLC home controller using broadband PLC technology which can save much cost at a network infrastructure using the existing power line at a home and design the USB home controller using USB technology which is low cost and has many goods with it. And the embedded home server manages those. The CDMA module provides mobile functions to the home control system in this paper. And we choose the OSGi specification which is compatible with other home middleware and can accept various communication techniques of home network

A home network is a residential local area network in which digital home appliances are connected with each other. Applying the mobile agent technology to the home network is expected to provide a new computing model. In particular, mobility and asynchronous ability of mobile agent can be used to reduce network traffic generated for managing home appliances. However, in order to apply the mobile agent concept to the home network, access control for mobile agents is necessary. In the existing home network system, there is one special server, sometimes called home server This server generally has mapping tables to be updated periodically, which describes access control lists between users' authorities and corresponding devices. In this paper, we propose a role-based access control framework with mobile agents in home networks. This framework, called Secure KAgent framework, is designed and implemented based on KAgent system. It has two main characteristics: to control access permissions based on Role-Based Access Control(RBAC) scheme and to safety assign roles to mobile agents by role tickets.
