Cluster Mesh Based Multicast Routing in MANET: An Analytical Study
Multicast streams are the most popular traffic pattern in many applications of Mobile Ad-hoc NETworks (MANET). However, the mobility of nodes causes frequent changes to the network topology and thus efficient routing of multicast traffic becomes very challenging. The establishment of a core-mesh has been deemed as a very effective solution for these dynamic setups. The core-mesh acts as a backbone in order to avoid frequent route discovery. However maintaining the core-mesh imposes significant overhead that dominates the performance for large networks. This paper advocates a novel methodology that combines network clustering and mesh-based multicast routing. The Cluster-Mesh based Multicast Routing (CMMR) methodology forms a backbone using cluster-heads.
