Multicast-Tree Construction and Streaming Mechanism for Intra 802.16 Mesh Networks

This work proposes a novel two-stage scheme for constructing an effective multicast tree. The first stage applies a priority-based algorithm to find suitable multicast points and construct effective multicast sub-trees. The second stage applies an interference-aware Steiner tree to connect the source to each multicast sub-tree. Finally, an algorithm generates the final multicast tree topology. Simulation results reveal that the proposed approach outperforms others in the construction of a multicast tree and significantly reduces the interference of a mesh network.
