The Multicast MAnet Routing Protocol (MMARP) aims to provide
multicast
In computer networking, multicast is a type of group communication where data transmission is addressed to a group of destination computers simultaneously. Multicast can be one-to-many or many-to-many distribution. Multicast differs from ph ...

Routing is the process of selecting a path for traffic in a Network theory, network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched ...

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 that 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.

An ad hoc routing protocol is a convention, or standard, that controls how nodes decide which way to route packets between computing devices in a mobile ad hoc network.
In ad hoc networks, nodes are not familiar with the topology of their netwo ...
