Simulation Environment: NS2
nExplored 7 routing protocols:
Ø2 Unicast protocols: AODV and DSR (come with NS2)
Ø3 Multicast protocols: MAODV (our implementation),
ODMRP, ADMR (NS2 versions made
available by Monarch Research Group)
Ø2 Broadcast Protocols: FLOOD (simple broadcast
protocol), BCAST (broadcast
protocol that reduces packet retransmissions: do not retransmit of there is no new neighbor that does
not yet know about the data
packet)
nThe “usual” simulation parameters: area of 1500m x 300m,
50 nodes, 802.11 MAC at
2 Mbps, at low or high mobility, 10
runs per scenario.
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
