On-demand overlay multicast in mobile ad hoc networks
Oliver Stanze, Martina Zitterbart · 2005
This paper presents the on-demand overlay multicast protocol (ODOMP), a novel approach for multicast data distribution in mobile ad hoc networks. ODOMP is a reactive protocol which creates an overlay among the group members on-demand. The created overlay is a source rooted tree which connects the group members via IP-in-IP tunnels. Routing is done by an arbitrary underlying unicast routing protocol. A novel creation mechanism allows ODOMP to create an efficient overlay with low communication overhead. The performance of ODOMP is compared with the performance of the well known multicast routing protocol ODMRP by means of simulations.
