In this paper, we propose the architecture of a wide area file service infrastructure, called I-Shadow. I-Shadow can provide both short delay file access and dependable file management for mobile users by using a set of active rules. We also show that average file access time of I-Shadow is shorter than that of cache based Coda distributed file system through a simulation study.
In this poster, we explore manipulation of an object represented by an image-based rendering approach in a 3D scene. We focus on two manipulation techniques that address the problems with using an image-based rendering approach and the constraints imposed by implementing such a system on a mobile device. We present results from our preliminary experiments.
