A Scheduling Method to Reduce Waiting Time for Node Relay-based Webcast Considering Available Bandwidth

Due to the recent popularization of digital web cast systems, delivering continuous media data, i.e. audio and video, has been attracted great attention. In node relay-based web cast, the server has better load balance by receiving data concurrently from other several nodes. Conventional methods reduce waiting time by sharing channels and receiving data from them. However, since the number of nodes by which the user can receive the data is one, occupation time of available bandwidth of the node increases. In this paper, we propose a scheduling method to reduce the waiting time for node relay-based web cast. In our proposed method, by considering available bandwidth of each node and producing an effective schedule, the waiting time is reduced.
