The document discusses the implementation of the Multicast Ad hoc On-Demand Distance Vector (MAODV) routing protocol. MAODV allows nodes in a mobile ad hoc network to send multicast packets and creates multicast trees connecting multicast sources and receivers. The project aims to implement MAODV in NS2 and evaluate the packet delivery ratio and latency. It discusses MAODV functionality, problems with the current implementation, and the methodology which includes creating a MANET scenario, implementing MAODV, and evaluating performance metrics.

• The Ad hoc On Demand Distance Vector (AODV) routing
algorithm is a routing protocol designed for ad hoc mobile
networks.AODV is capable of both unicast and multicast
routing.
• It builds routes between nodes only as desired by source
nodes. It maintains these routes as long as they are needed by
the sources.
• AODV forms trees which connect multicast group members.
The trees are composed of the group members and the nodes
needed to connect the members.
• AODV uses sequence numbers to ensure the freshness of
routes.
• Every node maintains a table, containing information about
which neighbour to send the packets to in order to reach the
destination.

• MAODV is the multicast extension of AODV .
• Both AODV and MAODV are routing protocols for ad-hoc
networks.
• MAODV allows every node in the network to sent Multicast packets
of data.
• AODV for unicast traffic and MAODV for multicast traffic.
• NS2 includes a standard implementation of the AODV protocol to
analyse its performance upon which we developed our initial
MAODV implementations.
• MAODV creates Multicast tree connecting multicast source and
receiver .These Multicast trees are maintained as long as group
members exists within the connected partition of the Group
MAODV

• MAODV allows each node in the network to send out multicast data
packets, and the multicast data packets are broadcast when
propagating along the multicast group tree.
• Each multicast group has a unique multicast group address. According
to the MAODV specification, each multicast group is organized by
using a tree structure composed of the group members and several
routers which are not group member but must exist in the tree to.
• We say the group members and the routers are all tree members and
belong to the group tree i.e. Associated with each multicast tree, the
group member that first.
• Constructs the tree is the group leader for that tree, responsible for
maintaining the group tree by periodically broadcasting Group-Hello
(GRPH) messages in the whole network.

• MAODV for multicast traffic.
• Only group members can send multicast traffic to the multicast
group.
• The multicast data packets are unicast , resulting in wasted
bandwidth.
