Paper Abstract:
|
The advancement in wireless network technologies has enabled the streaming media service on the mobile devices such as PDAs, laptops, navigation, wireless IPTV, and smart phones. The streaming media have larger and more complex data than the traditional text, picture image data. Furthermore, since mobile device users frequently use fast moving transportation and unstable wireless networks, the streaming media service for mobile clients is needed to study. In this paper, a client mobility-based media stream prefetching method to guarantee stable QoS in high speed mobile internet environment like a Mobile WiMAX, is proposed. In proposed method, high speed moving clients is joint a group depending on their characteristics and provided streaming media service according to a joint group. Mobile clients can change their group depending on their situation. In each group, clients' direction is predicted, and media streams are prefetched against disconnect and latency caused by handover. The proposed method is experimented and evaluated that buffer state is stable with handover for streaming media service. |
