| Modern technology promises mobile users Internet connectivity anytime, anywhere, using any device. However, given the constrained capabilities of mobile devices, the limited bandwidth of wireless networks and the varying personal sphere, effective information access requires the development of new computational patterns.{09}The variety of mobile devices available today makes device-specific authoring of web content an expensive and unattainable approach. The problem is further compounded by the heterogeneous nature of the supporting networks and user behaviors. The notions of "typical user" and "typical user behaviors" are no longer applicable for many Internet applications. This research investigates the challenges posed by these problems, and proposes a context-aware adaptation framework (FACADE) to bridge the gap between the existing Internet content and today's heterogeneous computing environments and users. A proof-of-concept implementation of the architecture is implemented and tested, and the effects of context-aware content adaptation on application usability are analyzed. The evaluation of the proposed framework suggests that the system is capable of increasing usability of web applications for mobile devices by decreasing response time and size, and hence increasing application efficiency. |
