A Scheme for Probabilistically Reliable Multicast Routing in Wireless Mesh Networks
Xin Zhao, Chun Tung Chou, Jun Guo, Sanjay Kumar Jha · 2007
In this paper, we proposed a probabilistically reliable multicast routing (PRMR) which uses link packet delivery rate as the link-quality-based metric to find paths from source to destinations. In order to increase the reliability of the multicast session, we use a pair of disjoint paths to connect the source to each destination. We reduce the total number of forwarding nodes by exploiting the wireless broadcast advantage. Our experiment results show that PRMR can increase the average reliability by up to 25% and the node with the lowest reliability by up to 50% in comparison with ODMRP.
