A Source Based Multicast Scheme in IEEE 802.16 Mesh Mode

WiMAX based on IEEE 802.16 is known as one of effective technologies for transmission of multimedia to groups of receivers. There are two operational modes in WiMAX: Point to Multi Point (PMP) for single hop transmission and a mesh node for multi-hop transmission. The current standard only defines unicast transmission under mesh mode thus the performance is deteriorated for multimedia applications with multicast nature. In this paper, the authors first propose a mechanism for source-based tree topology construction aiming at facilitating multicast transmission in WiMAX mesh network.
