The purpose of this paper is the design and implementation of asynchronous remote procedure call (RPC) resource service system using the XML technology. For this purpose, the request information of client is encoded into XML document based on XML-DOM and transferred to server, Server classifies the client requests into general application program and XML-RPC service using the object which can deal with the XML-DOM. In addition, server saves the request result of client in XML-DOM structure not transmitting it immediately in order to support asynchronous service, and makes the client request redirected to another request server in XML-DOM information. As a result, general RPC and XML-RPC services were attained and client request was redirected to servers, and the execution environment was simplified compared to common RPC.

It has been increasing that the use of Mobile Internet these days. And the demand of user is changing from the text based services to multimedia based data services like pictures, sounds and streaming videos in Mobile Internet. In this paper, It is proposed a remote monitoring system that .an transfer the video data through WAP(Wireless Application protocol) based Mobile Internet used generally in anywhere. And this system is a low-cost efficient system compared with a existing high-cost Internet Camera system, using video module connected to Internet directly and PC-based server. In this paper, It is explained a design and implementation of such WAP-based remote monitoring system.

The trend of Internet of things are changed from public and examples of corporate center to B2C service. As you can see, through the practice of domestic and international services Internet of Things, conventional disaster, disasters, such as the case of the public sector, factory automation company now mainly direct B2C (Business to Consumer) services are affecting the individual has spread. In this paper we propose a method of platforms and components, and network configuration plan for exploration robot design based on remote control and monitoring system with IoT.

Sensor application systems for remote monitoring and control are required, such as the establishment of databases and IoT service servers, to process data being transmitted and received through radio communication modules, controllers and gateways. This paper designs and implements database server, IoT service server, data processing middleware and IoT management system for IoT based services based on the controllers, communication modules and gateway middleware platform developed. For this, we firstly define the specification of the data packet and control code for the information classification of the sensor application system, and also design and implement the database as a separate server for data protection and efficient management. In addition, we design and implement the IoT management system so that functions such as status information verification, control and modification of operating environment information of remote sensor application systems are carried out. The implemented system can lead to efficient operation and reduced management costs of sensor application systems through site status analysis, setting operational information, and remote control and management.

When developing an android mobile application the androids intent is used as a mechanism to send messages between local equipment of androids application inner part and other applications. But the androids intent does not support sending messages via each android products intent. If there is a way to support each androids equipments to send messages, it will be easier to make non-stopping services. Non-stopping service is used when the user is using the android to do word or searching services and suddenly changes to a different android product but still maintains the progress what was currently being done without waiting the programs to be loaded. It is possible to send messages to each android products by using the socket, but the connection must be maintained stably which is the weak point. In this paper, I am suggesting a BRIF(Broadcasting Remote Intent Framework) framework to send messages to different android products. BRIF is a framework that uses the Googles C2DM service which services asynchronous transmissions to different android products. This is organized with the C2DM server, RemoteContext Api, web server and RISP(Remote Intent Service Provider) which is will be easy to be used for the developers since there are no big changes for coding compared to the intent code.

There are two reasons that the remote medical is newly embossed. One is the development of the info-communications technology that is possible to the remote diagnosis. Another is changing the thinking about the new medical services for the offerers and consumers. Therefore, we suggest the mobile-environmental remote diagnosis system. The system could apply more efficient connection with the very fast developing diagnosis and medical treatment.

In this paper, we proposed service security model and remote management service on OSGi computing environment. The model is used to make access control decisions like permission-based security inside the java2 platform. In model, policies are defined using a flat text file and include bundles. It method granted flexibility and extendability of access control of bundles and services. Also, we proposed service architecture efficiently for remote management service.

In this paper, we describe the internet-based remote home automation system that con control and manage home appliances or digital devices bi-directionally through Internet. The platform-independency of VRML and Java applet enables users to access their home appliances and to check current state of them in t he virtual reality environment. The main focus is on three aspects. One is on the virtual reality technology to support the user interface efficiently by using 3D GUI in web-browser. Another is on the system architecture that consists of Home server and its manager server called Gate server in this paper. These servers have been implemented by Java RMI which is the basic single programming interface for distribution of objects and services using Java technology. The third, remote PLC controller and each digital devices are composed of home networking by PLC using CEBus protocol.
