A Scheduling Method on Selective Contents Delivery with Node Relay-based Webcast Considering Data Size

Due to the recent popularization of digital broadcasting systems, selective contents broadcasting depending on users' preferences have attracted great attention. Although the server can deliver programs reflecting users' preferences, clients have to wait until their selected contents start playing. Conventional methods reduce the waiting time by producing an effective broadcast schedule. Although the server can deliver programs that meet users' preferences, clients have to wait until their selected contents are delivered. In this paper, we propose a method to reduce the waiting time on selective contents delivery with node relay-based webcast that relay data among nodes. Our proposed method reduces the waiting time by scheduling contents considering available bandwidth of each node.
