Image and Video Quality Assessment

Digital terminal mobility is becoming more and more effective. Wth this in mind, we have been led to question existing applications, systems and networks while integrating this mobility into architectural models. Moreover, mobile equipment performance is increasing and processing video sequences is possible with good-quality restitution. Given the large scale of video sequences, delocalized management is necessary but to achieve this, new filing strategies for video data must be conceived. Indeed, storing data on a static cache located on a wired network to serve a client leaving the area, proves to be useless and will penalize the system performance. In this paper, we propose to integrate this mobility into the cache management, storing data not only in the nearest cache but also on neighboring caches, depending on clients' movements.
