Abstract

Most adaptive multimedia multicast applications require the source to select the number of streams to transmit as well as the QoS parameters for each stream. If the receivers have different bandwidth limits for their devices and have various preferences for the quality of the data, selecting the QoS parameters that generate the best average satisfaction for all receivers is a challenging problem. In this paper, we developed a selection algorithm that is based on the user profiles and the device capabilities. Receivers are required to send their profiles and the bandwidth limitation on their devices to the source once before the session starts. To avoid the implosion problem and have a constant running time for the selection algorithm, we partition the receivers according to the bandwidth limit of their devices into classes and use a virtual representative for each class of receivers.
