Hi,
If you want to see wireless topology in nam
your have to do following addition to your scripts
first, you have to use
set namtrace [open wireless.nam w]
$ns_ namtrace-all-wireless $namtrace $val(x) $val(y)
where val(x) n val(y) should be having your grid range. or you can specilfy
it directly here like 800 800
second, just after where you declare initial node positions, you need to add
following code
for {set i 0} {$i < $val(nn)} {incr i} {
$ns_ initial_node_pos $node_($i) 30 ;
}
where val(nn) would be containing number of nodes. node_($i) is node
array and 30 denotes the size of node displayed in nam.
After this much, after simulation run, there 'll be file
wireless.namcreated. you can execute it by typing "nam
wireless.nam"
or you can add a line in your finish procedure
"exec nam wireless.nam &"
Thats it as for as topology is concerned, or node movements but
unfortunately you can't see packet flow of wireless simulation in nam.
For Xgraph files etc... See marc Greis tutorial section VIII. Creating
output files for XGraph.
Best of luck.
