  Abstract

The purpose of this study is to enhance the quality of multimedia service under the heterogeneous end-terminals and network environment by monitoring the data receiving status of the group members regularly when the sender multicasts real-time multimedia data to a group. Especially, it focuses to reduce the total number of status information responded to the sender from the receivers. Accordingly, it upgrades the sender's performance by suppressing the number of status information packets generated by the receivers. The key idea of this study starts from how we profile the activity of all the members in a group. We assume that the receiver status in the worst status, so called primary receiver, represents the status of the whole group. This means that the whole group is assumed as being degraded in performance if the primary receiver is degraded, and that the whole group is assumed as being upgraded if the primary one is upgraded. In this algorithm, the primary receiver announces its status information to the whole group prior to other receivers, and every receiver listening to the primary and other receivers status compares its own status with them. Accordingly any receiver may give up the status notification in case its status is not worse than others, resulting in the reduction of unnecessary responses to the sender.
