• 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.
