ADAPTING HTML CONTENTS FOR WAP DEVICES USING JAVA SERVLETS

Abstract

After the world wide web, the next big challenge to the Internet is mobile access. More and more information is available on the Internet and intranets and mobile users will also need access to it. These devices are characterized by low network bandwidth, high latency time, small display size, low computational capability. Wireless Application Protocol (WA P) together with Wireless Mark-up Language (WML) constitute an open architecture for mobile web services designed with these limitations in mind. To date, most web resources are authored in HTML with the desktop as the client device where resource is hardly a constraint. For the WAP devices to access these web documents, contents need to be converted into WML keeping in mind the resource constraints of the mobile devices, In this thesis we have described a content adaptation technique applied to HTML documents from a specific domain area - news web sites, since receiving news updates is one of the most important application of mobile Internet access. We have implemented a content adaptation system that extracts the most important information from the news sites, converts them into WML for display on WAP devices. As test platforms to display WML content, we have used WAP device simulators. This approach gives the mobile users transparent access to their familiar web pages from their mobile phones and other mobile devices.
