The radio range is about 627 meters. The terrain size is set to 900x900m.dsr_3nodes.nodes.conf

1.2 trafficNode0 is sending CBR traffic to Node2, which is out of 1 hop range to Node0. Thus a DSR route discovery and forwarding is mandatory.

1.3 protocolsThe 3 nodes run DSR as routing protocol, and 802.11 as MAC protocol.

1.4 Run and Analysis
Run the simulation:
glomosim dsr_3nodes.sim.conf > sim.log
Analysis the output stat file with awk script:
awk -f dsr_3nodes.awk dsr_3nodes.stat
Results:
