Interactive 3D environments have been studied for years and represent an important application area of computer graphics. However, high quality virtual environment interaction requires powerful computers equipped with expensive graphics accelerator cards. The high 3D data volume and the dynamic nature of bandwidth pose significant challenges when providing a smooth virtual navigation on thin mobile devices over wireless ad hoc networks. In this paper, we show that it is possible to provide a virtual environment walkthrough on mobile devices through a client-server approach. Although mobile devices have low processing power and memory, they can still render images with relative ease. Based on this fact, instead of using traditional geometry-rendering techniques and locally rendering complex scenes, we employ an image-based mechanism on the client that uses images, which are provided by a remote server through an interactive streaming transport protocol. In this paper, we propose a bandwidth feedback algorithm together with a rate control and virtual user path prediction to better adapt the system to the changing bandwidth. We also discuss our ideas and show an extensive set of simulations in order to evaluate the performance of our solutions.
