Hand-over video cache policy for mobile users

Laboratoire d’Informatique de l’université de Franche-Comté Abstract. Nowadays, wireless links are shared between clients and the available bandwidth fluctuates, so the video stream must be adaptive in order to optimize the transmitted quality. In this article, we present a tool called MoVie to distribute multimedia streaming on large wireless networks. The two main aspects of MoVie deal with network access and managing systems. The management of video streams is realized using video caches linked to a physical area. This article describes the policy used to take into account the mobility of the clients and the hierarchical aspect of the streams by preparing the neighboring caches to receive roaming clients
