A Performance Comparison of Multipath Multicast Routing Protocols for MANET

Mobile Ad hoc NETworks (MANETs) are characterized by dynamic topology, limited channel bandwidth and limited power at the nodes. Because of these characteristics, paths connecting to the source nodes with destinations may very unstable and go down at any time, making communication over ad hoc networks difficult. Multicasting is intended for group-oriented computing. Multicast generally needs a tree construction that connects all the members of the multicast group as well as the nodes where data packets are duplicate. In this paper, the authors compared the multicast multipath routing protocols. The MAODV (Multicast Ad hoc On-demand Distance Vector) routing protocol shows a smooth performance in light load ad hoc networks. However, as degraded quickly.
