Abstract
We analyze the access behavior and traffic characteristics of typical mobile services, study and compare the performance of different adaptation approaches. For a typical unified Web site, 10% of access requests are from mobile users, 90% from PC users. The heterogeneity in the communicating devices and networks QoS characteristics need to be handled through different forms of software-supported adaptation. The two main adaptation models are server-based model and proxy-based model. The processing load of server or proxy carrying out the adaptation may increase by about 10 times or more. In order to provide differential services and increase the scalability, the server-adaptation and proxy-adaptation should coexist. They are suitable for paid and free services respectively. Paid services account for about 80% of mobile traffic, and free services account for 20%. Server and proxy processing capability should be increased by more than 2 times. Thus traffic and processing load is divided rationally.
