Previous work: studied performance of multicast and broadcast protocols in NS2, determined that broadcast protocols can support one-to-many and many-to-many communications well in a MANET
Choose BCAST as starting point, a protocol that utilizes
2-hop neighborhood information
to dynamically prune re-broadcasts
However, even for best broadcast protocol, Packet Delivery Ratio (PDR) can be reduced when
Mobility increases
Number of multicast sender (i.e., traffic) increases
