Abstract
Information access through WWW on the Internet has become an important service for mobile clients due to rapidly growing diversity of wireless communication devices. However, common web pages of HTML (or XML) are designated around the desktop PC environment, it is not suitable for mobile clients with small size of screen, low quality of display resolution, insufficient computing power, and narrow-band wireless communication networks. Recently, a plain version of XML, called WML, has been nominated to serve as a new standard in web browsing for mobile devices. However, at the moment the quantity of available WML pages is relatively small comparing to the number of existing HTML pages that is still growing at an incredible rate. And users may be used to browsing information from the existing HTML pages that they access with desktop PC at home. So it is helpful if there exists a solution for mobile devices with WML browser to access the existing, innumerable HTML pages. In this thesis, we present a system for providing an effective gateway service to translate the content on an HTML page to a set of WML decks such that the mobile clients can get the necessary information through WAP. Our system delivers the partial information to the mobile device users they acquired, instead of the whole page obtained in a regular web page access. Thus, it can significantly reduce the amount of transmission on wireless networks. In the experiments, WML browsing through our system costs only 41.6% of the transmission data of HTML browsing in average case.
