QoS multicast routing scheduling for multimedia applications in wireless mesh networks

Abstract

In this paper, we propose a QoS Multicast routing routing scheduling scheme that satisfies the network conditions with the delay constraints. It is designed to adapt to a dynamic node condition of participating and leaving from the multicast group. After the delay tolerance and the maximum group size are determined according to network state and requirements, we construct the dynamic QoS multicast tree using partial multicast routing scheme. We evaluate the performance of the proposed scheme with randomly generated wireless mesh network, by choosing the optimal values for delay bound in response to the changes in multicast group membership. © 2012 Springer-Verlag.
