The more mobile devices consuming web services, the more QoS-aware selection of mobile web services, we need. A QoS(Quality of Service) contract is an agreement between the web service provider and the mobile user that specifies the level of the service quality. Web services users can be assured of the level of the service quality specified by the QoS contract. We propose a broker-based framework for QoS-aware mobile web services selection in this work. Under this architecture, the mobile users can request the web services through the service broker on the wireless networks. The service broker utilizes agents to monitor the web services quality and manages the service quality by notifying the service provider and mobile user of the service contract violation. Reliability, response time, and cost were the metrics used for QoS monitoring. Futhermore mobile users can select a web service best suited for his/her needs through the service broker.

In this research, we developed a scalable resource monitoring system for large scale scientific computing data centers. Usually, there are limitations and overheads for keeping track of every computing nodes because of the huge number of computing nodes. So, this research proposes a layered summarizing techniques during collection of all system resource information. The technique results in improved scalability by reducing the amount of information at higher layer. Our prototype system which is implemented with web service is applicable with the HTML5 mobile web technology on smart devices.

Scientific and technological research data is increasing exponentially and, Kisti(Korea Institute of Science and Technology Information) built and supported GSDC(Global Science experimental Data hub Center) depending on the needs processing large data computing and storage devices. Mobile web standards-based the MUPS was built for global community and services of gsdc to spreading mobile devices rapidly. And for analyze Operational status and system resources of GSDC at n this paper researched and implemented system resource monitor method of gsdc to mobile web environment, in this paper researched and implemented system resource monitor method of gsdc to mobile web environment. Research support system of GSDC operated by scientific linux. Sysstat resource monitoring tools create a daily report through sar(system analysis report), after sadc(system activity data collector) collected system resource utilization information. In this paper, sar reports designed and implemented in mobile web to can visualize in a mobile environment. We do not depend specific OS by implementation of the mobile web. So we are available in variety mobile OS. And through provided visual graph, this system can monitor easily and more conveniently then the existing system.

The BBS of Web Site is a space of informational communication to share information. At the moment, countless information is shared through various kinds of BBS. The shared information through the Web BBS can be gains to someone and losses to the other. Thus, for a long time, there have been many researches about technologies, which monitor information uploaded to Web BBS in real-time and inform the results to subjects. For BBS monitoring, existing methods have utilized direct approaches to DB or open API. Also, e-mail addresses have been utilized to inform results to subjects. However, there are two main problems for these methods. The one is a problem on closed BBS, which cannot be accessed, and the other is impossibility of supporting real-time alarm to e-mail. Especially, the real-time support for services, such as monitoring, is extremely important, since the main purpose of monitoring is based on the counter action for the result. The mobile Web has a merit to be accessed in anywhere, so that it is quite suitable for services requiring real-time support. However, the real-time support of mobile device has not been utilized enough, because each mobile phone has different standards of contents so that the contents should be pre-created. This paper suggests a technology that overcomes pitfalls of mobile Web while it is out of standard, and shows how the effect can be maximized through services such as monitoring, which requires the real-time support.

최근 효율적인 교통 흐름 제어 및 교통정보 서비스 제공을 위한 ITS(Intelligent Transport System)에 대표적인 서비스로는 수집된 정보를 바탕으로 도로의 소통정보를 모니터링하고 이용자들에게 웹이나 지역에 설치된 VMS를 통해 정보를 제공하는 것이라 할 수 있다. 그러나 이러한 서비스를 위한 GIS가 OpenGIS와 같은 표준화 단체에서 제안하고 있는 구조를 따르지 않고 있으며, 지리정보의 표현도 검증 없이 자체적으로 GIS정보를 이용함으로 인해 서비스의 성능과 품질 저하는 물론 정보통합의 어려움을 가지고 있다. 본 논문에서는 OpenGIS에서 공간정보 표현에 권고되고 있는 GML을 기반으로 도로망에 구축되어진 각종 교통정보 기기로부터 ITS로 수집된 실시간 교통정보를 이용하여 데이터베이스를 구축하고, 이를 반영하여 모바일 기기 또는 웹서비스를 통해 교통상황을 모니터링 할 수 있는 시스템을 제안하고자 한다. 제안된 시스템은 GML을 기반으로 한 지리정보 DB와 각종 교통정보 기기로부터 수집된 실시간 교통정보의 통합을 통해 모바일 기기나 웹을 통해 공통적으로 서비스를 제공할 수 있는 Client/server 시스템에 주안점을 두고 설계하였다. 본 연구에서 설계된 시스템은 전용 공간데이터를 구축하지 않고, 표준화된 공간정보인 GML을 이용한 변환 메커니즘을 통하여 서비스를 제공함으로써 비용과 시간을 절약할 수 있으며, 이 기종의 시스템에 서비스가 가능하도록 하였다.

A monitoring system needs many parameters to increase devices for monitoring data and to support various services. In particular, monitoring the status of a device in a wireless mobile environment has a difficulty in displaying multi data in a limited screen size, and transfer of the status data of a device into a network is largely related with network traffic. The research aims at designing a control board that collects data in order to effectively manage a greenhouse environment system. Also, the research tries to appropriately operate devices, environment data monitoring, and the control of each device by realizing a multiplexed interface based on a web. Thus, in the case in which a distributed client was a computer, monitoring and control were obtained with a web browser through the Lab VIEW web server of a server or local control module in order to effectively monitor and control according to the status of a user. In the case in which a client was a PDA, application of a wireless mobile considering the scale and data processing capacity of a displayer was connected. As a result of the research, we could confirm a satisfactory outcome from the viewpoint of a human-centered design by supplying adaptability and mobility according to the environment of a user.

The Mobile device like smart phone is a small computing device and easy to carry around. The Mobile devices are wildly being used as desktop personal computer and can served individual services. Because of compatibility of applications working on mobile devices are not good, so developer need to develop it that match changes in platform fetures. In this paper, we design and implementate ubiquitous healthcare monitoring system that can be runs on many different platforms using HTML5 as a standard web development language and jQuery as a javascript library. Ubiquitous healthcare monitoring system is runs on on many different platforms like mobile platforms and desktop web browsers.

This paper contains the results of the development and performance evaluation of the environmental data monitoring system for the fish farm. For the hardware development, the analogue sensor is used to collect dissolved oxygen, pH, salinity, and temperature of the fish farm water, and the digital sensor is used for collecting ambient temperature, humidity, and location information via a GPS module to be sent to cloud-based Firebase DB. A set of LoRa transmitters and receivers is used as a communication module to upload the collected data. The data stored in Firebase is retrieved as a graph on a web and mobile application to monitor the environmental data changes in real-time. A notification will be delivered if the collected data is outside the determined optimal value. To evaluate the performance of the developed system, a response time from hardware modules to web and mobile applications is ranging from 6.2 to 6.85 seconds, which indicates satisfactory results.
