A lantern-tree-based QoS multicast protocol for wireless ad-hoc networks
2002
In this paper, we propose a lantern-tree-based QoS multicast protocol with a reliable mechanism for wireless ad-hoc networks, where the MAC sublayer adopts the CDMA-over-TDMA channel model. In this paper, we identify a lantern-tree for developing an on-demand QoS multicast protocol to satisfy certain bandwidth requirements from a source to a set of destination nodes. The lantern-tree serves as the multicast-tree. Our lantern-tree-based scheme offers a higher success rate to construct the QoS multicast tree due to using the lantern-tree. The lantern-tree is a tree whose sub-path is constituted by the lantern-path, where the lantern-path is a special multi-path structure. This greatly improves the success rate by means of multi-path routing. In particular, our proposed scheme can be easily applied to most existing on-demand multicast protocols. Performance analysis results demonstrate the QoS achievements of our proposed protocol.
