The World Wide Web has become an essential tool as well as an entertainment medium in our daily life. However, efficient web browsing from anywhere at anytime, presents an opportunity as well as a challenge to the web document authors. The mobile users have a totally different requirement compared to the conventional wired users. The mobile networks have limited bandwidths, and the mobile terminals have limited resolutions. Hence a scheme is needed to adapt the web-data and multimedia contents such that they can be used on devices with limited resources such as bandwidth, resolution and memory space. In this paper we propose a novel mobile proxy server architecture suitable resource-limited multimedia terminals. Here, a distributed method is employed to adapt the multimedia data such that the adaptation is neither fully based on the proxy server nor fully based on the web server. Adaptation process is expected to be faster since the data adaptation loads are distributed between the proxy and the web server. Simulation results suggest that a significant performance improvement can be achieved with the proposed architecture.
