A Mobile Ad-hoc NETwork (MANET) is a collection of mobile nodes. It can be constructed anywhere without any infrastructure. The mobile nodes are equipped with energy-limited batteries. An important issue in such a network is to minimize the total energy consumption for each operation. In MANET each node acts as a store and forward station for routing packets. As the nodes are highly dynamic, maintaining routes become a greater challenge. Multicasting is one of the fundamental mechanisms, which can be typically implemented by creating a multicast tree. It is achieved by forming minimum spanning tree between the source nodes and other mobile nodes in the network and then data is transmitted over this minimum path.
