Design and implementation of a web service agent for mobile devices

Abstract

The advent of the new technology in the wireless network environment has made the people more enthusiastic in using mobile devices. WI-Fi, one of the wireless standards, is becoming popular, particularly, in our homes, offices, railway stations, airports etc. The professional users want to use hand-held devices to access the information from the internet during traveling or walking. Web services, one of the technologies in computer sciences, are becoming the middleware standard in the future and make the people to gain access to the required information. Sometimes this enthusiasm makes the people to use a particular web service application in their hand-held devices, which combines a number of web services to collect information and concludes some result. It can be difficult to use such type of web service application due to the limitations in hand-held devices. It can also degrade the quality of service in accessing the web services in the wireless environment. We need to gain the quality of service for the users. We need to make the web services more accessible to gain the quality of service. We need to adopt the ways according to the needs to make the environment more efficient for the people. We propose an implementation that makes the environment more efficient for the people. This implementation is a Web Service Agent for mobile devices to have access to the web service application that is running in the desktop computer to make the web services more accessible for the users. This Web Service Agent consists of two-program modules. The one runs on the PDA called Service Invoker, the other runs on the desktop computer, where the web service application is running, called Service Invoking Agent. We have conclude that our implementation can enhance not only the quality of service to access the web services but also save the resources of mobile devices such as memory capacity and battery power.
