Simulation Environment
nNS2 simulations to validate literature results
nExplored 3 protocols:
ØFLOOD: simple broadcast protocol
ØBCAST: broadcast protocol that reduces packet
retransmissions (do not
retransmit of there is no new neighbor that does not yet know about the data packet)
ØODMRP: mesh-based multicast protocol
nThe “usual” simulation parameters: area of 1500m x 300m,
50 nodes, 802.11 MAC at 2 Mbps, at
low or high mobility.
Ø1, 2, 5, or 10 senders
Ø10, 20, 30, 40, or 50 receivers
ØEach sender sends a 256 byte packet every 500 ms
nPerformance Metrics: Packet Delivery Ratio and Packet Latency
