A Comparative Survey and Issues in Multicast Routing Protocols for Mobile Ad-Hoc Networks

A Mobile Ad-hoc Network (MANET) is composed of Mobile Nodes (MNs) without any infrastructure. Mobile Nodes self-organize to form a network over radio links. Multicasting can efficiently support data transmissions and thus is very suitable for MANETs. Implementing multicast routing protocols to MANETs leads to improve the consumption of bandwidth, reducing the cost of communication in the network and improving the efficiency. In this paper, we provide an overview of multicast routing mechanism especially in routing based on mesh and tree topology.
