MMARP

The Multicast MAnet Routing Protocol (MMARP) aims to provide multicast routing in Mobile Ad-Hoc Networks (MANETs) taking into account interoperation with fixed IP networks with support of IGMP/MLD protocol. This is achieved by the Multicast Internet Gateway (MIG) which is an Ad-Hoc node itself and is responsible for notifying access routers about the interest revealed by common ad-hoc nodes. Any of these nodes may become a MIG at any time but needs to be one hop away from the network access router. Once it self-configures as MIG it should then broadcast periodically its address as being the one of the default multicast gateway. Whoever besides this proactive advertisement the protocol states a reactive component the Ad-Hoc Mesh is created and maintained.

When a source node has multicast traffic to send it broadcast a message warning potential receivers of such data. Receivers should then manifest interest sending a Join message towards the source creating a multicast shortest path. Also in the same way the MIG should inform all the ad-hoc nodes about the path towards multicast sources in the fixed network.
