An Adaptation Control Model to Support Mobile Web Access

A mobile environment is characterized by low communication bandwidth and poor connectivity. Efficient Web access over a wireless network is challenging because of the varying characteristics of different devices constituting the wireless environment and the adverse interactions among HTTP, TCP and the wireless network. These lead to problems that significantly degrade the user-experienced performance of the web accessed through the wireless network. We have developed techniques to visualize web access in a mobile environment – the proxy-agent mobile document clustering architecture (PMDC). The PMDC architecture allows the mobile users to visualize and navigate through the Web structure without having to download all related links in a Web site. The Proxy-Agent model provides facilities for adaptation in a mobile environment.
