AM-SRL: Adaptive Multicast operation of the Supernode-based Reverse Labeling algorithm

In this paper, the supernode-based reverse labeling (SRL), a quality of service (QoS) routing algorithm for mobile ad hoc networks (MANET), is extended to provide adaptive multicast service. The algorithm, termed AM-SRL (Adaptive Multicast operation of Supernode-based Reverse Labeling), adaptively builds an on-demand multicast mesh by exploiting the hierarchical structure of SRL. The virtual route discovery process of SRL functions as multicast member distribution awareness agent in AM-SRL and the reverse route establishment algorithm enables the adaptive generation of the multicast mesh. AM-SRL guides the redundant level of the multicast mesh by introducing a partial mesh factor. The adaptivity of virtual route selection, reverse route establishment and mesh formation make the algorithm efficient, robust and reliable.
