A Scheduling Method for Node Relay-based Webcast Considering Reconnection

Due to the recent popularization of digital broadcasting systems, selective contents broadcasting depending on users´ preferences with node relay-based web cast have attracted much attention. In node relay-based web cast, waiting time is reduced by receiving contents from several nodes. However, when a node that delivers contents disconnects from the network or reconnects to it while delivering contents, waiting time increases by changing a delivery schedule. In this paper, we propose a scheduling method considering reconnection on selective contents delivery with node relay-based web cast that relay data among nodes. Our proposed method reduces waiting time by restructuring the delivery schedule considering the disconnection and the reconnection of the node.
