Conclusions

nMAODV has poorer packet delivery ratio

ØMAODV uses a shared tree for data dissemination. If a single tree link breaks because of node movement, packet collision, or congestion, destinations cannot receive packets

ØODMRP provides redundant routes with a mesh topology and the chances of packet delivery to destinations remain high even when the primary routes are unavailable

nODMRP suffers from scalability issues as the multicast group increases or the sender size increases

ØODMRP maintains per-source meshes connecting receivers and senders. As the number of senders increase, periodic Join Query packets increase, causing higher amounts of congestion and control overhead

ØMAODV uses a single multicast group leader to send out periodic Hellos through the network. Increasing the number of senders has minimal impact
