hi all, when i am trying to set the positions of base station using below # Create HA and FA # Position (fixed) for base-station nodes (HA & FA). set HA [$ns_ node 1.0.0] $HA random-motion 0 $HA set X_ [expr $opt(x)/2-50] $HA set Y_ [expr $opt(y)/2-50] $HA set Z_ 0.000000000000
set FA [$ns_ node 2.0.0] $FA random-motion 0 $ns_ at 0.0 "$HA label HA" $ns_ at 0.0 "$FA label FA" $FA set X_ [expr $opt(x)/2+50] $FA set Y_ [expr $opt(y)/2-50] $FA set Z_ 0.000000000000 but in nam, only FA base station is at the specified location HA position is varying if link delay changes . i don't know how it is happening so please help me to set the positions of base stations thanks in advance
