Recently, most of the embedded system have the function of multimedia information processing and network connecting. This make the overall system more complicated and need a new approach. Moreover the embedded system must be real-time system, which are different with Linux is constructed and the kernel is redesigned on the strong-arm board in order to make the real-time embedded web-server system.

According to the evolution of the Internet and wireless mobile communication technology, techniques for mobile databases and wireless web services are issued for them. Recently, these changes of geographic application environment increase the needs for development of new GIS database system for the web services and embedded system. In this paper, we proposed a Jana-based web database systems that can be used in the web-based GIS and mobile databases. This proposed system has been implemented using the Java to be displayed easily into the portable computing devices and Java-based web application servers and using OpenGIS for web data interoperability. Also, it can efficiently process web-based spatial queries by developing a spatial query processor including schema manager and a spatial object storage module.

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.

The use of IoT (Internet of Things) is rapidly expanding to enhance the quality of life as seen in the interconnection between mobile devices and Web. This paper proposes an embedded system that connects sensors and mobile devices via IoT technology, improving the user's ability and service experience to remotely control the home appliances with mobile-detection features. Home appliances are expected to increase labor efficiency by utilizing the embedded system connected to the sensors. Using mobile applications to control home appliances remotely and to monitor operation status advances the user's knowledge, experience, and perspectives to experience refined life qualities.

A realization for the wireless transmission system on the Un image using embedded server is presented on the paper to be simply to omni-direction data acquisition. The embedded system is composed of the image data acquisition which has CMOS sensor and lame grabber, the embedded server that takes the wireless LAN target board, and client part that is monitoring the image from the embedded server. The experiment result is average 12.7fps in 8bit on the 320$\times$240, 4:2:2 YCbCr. The system enable images transmission to be soft . monitoring.

The SPARTAN-3E development kit is equipped with an FPGA which holds 500 thousand logic gates and a bus system platform using MicroBlaze microprocessor system. This kind of embedded systems can be used to gather information from sensor nodes and send over to the main server periodically through the network gateway, using the microprocessor-based embedded system, so that edlers living alone under sensor coverage can send their moving information and can be applied to get help in the event of emergency situations. In this paper, we designed a simple embedded system based on a CPU and flash memories using such FPGAs which can be used to monitor those elderlies living alone. The developed hardware system can be directly combined with the web-based elders-living-alone monitoring system, making the system more efficient.

The Embedded Linux System has been developed as a system which can be used with a processor of low efficiency and small-sized memory. Unlike the usual Linux and Windows web server, it has some limitations in the install of application programs, compatibility and scalability when transferring data through web server in real-time. In this paper, we present a real-time remote monitoring system which is very useful to the embedded linux system. The presented system use Java Script without the additional programs at the Embedded Linux System web server and confirm the efficiency of the system through the existing real-time remote monitoring techniques.

In this paper have embodied a TCP/IP based small embedded web server and proposed the technical method for monitoring the real-time system states and remote controlling system using HTTP about manipulator joint angle. This also uses TCP/IP, which is the general protocol. and it is made of software, not of the TCP/IP stack with hardware chip. Then we attach the simulating results about the manipulator's input/output via web browser.

A remote monitoring system of the semiconductor equipment is used to monitor or control operations of the equipment. Most of the conventional monitoring systems are based on the client-server model with the general purpose PC. Basically, it implies the difficulties in the system reliability and cost down due to its size and complexity. To overcome these difficulties, we suggest an embedded web server which is based on the low-cost microprocessor. It is designed for the monitoring or controlling a dedicated equipment only. To evaluate the feasibility of the suggested embedded web server, we have implemented a test-board with ATMega103 and programmed the basic modules using the AVR-GCC. Finally, we have tested its operations on the MS Explorer 6.0 environment.

In this paper, a Web-based management system for the building network is described. A multi-protocol converter based on SoC and embedded Linux is designed. The open source licensing, reliability, and broad hardware support are key reasons for use of embedded Linux in embedded industry. The multi-protocol converter integrates control network of RS-485 and LonWorks devices through TCP/IP protocol for a client with Java applet. The system consists of three-tier architecture, such as a client, a server that is performed on a multi-protocol converter, and control devices. The developed system includes the inverter motor control system with modbus protocol for the RS-485 network. The experiment results show that the multi-protocol converter using embedded Linux is a flexible and effective way to builda Web -based monitoring and control system.
