Maybe. If you attach the tcl file as name.tcl.txt .

The errors in post #1 are generic.
Any faulty file.tcl can cause similar errors.

[QUOTE][Maybe. If you attach the tcl file as name.tcl.txt ./QUOTE]

I execute the file with the extension .tcl not .tcl.txt

this is the file
dccp-wifi-lte.txt

note i execute with the extension .tcl in the simulator

← #3 .

Reason for suffix .txt :
Text files must have suffix .txt to be attached.

Reason for suffix .tcl :
It's nice when the file can be recognized in your post (#3) as a tcl file.

I.e. the correct naming for the attachment is " dccp-wifi-lte.tcl.txt ".
(And you can also easily run the file with $ ns dccp-wifi-lte.tcl.txt
... A file.tcl isn't executed, but is interpreted by 'ns'.

Your error "bss_id lookup failed" : Where is "bss_id" defined ?

Here where i defined bss_id
#création de la station de base
set PA [$ns node 2.0.0]
$PA random-motion 0
#provide some co-ord (fixed) to base station node
$PA set X_ 250.0
$PA set Y_ 250.0
$PA set Z_ 0.0
set PAMac [$PA getMac 0]
set AP_ADDR_0 [$PAMac id]
$PAMac bss_id $AP_ADDR_0
$PAMac set-channel 1
$PAMac enable-beacon
[$PA set netif_(0)] setTechno 802.11

It's a tcl code for creation a BS
actualy i copied this one from another file but it have also the same problem that is why i ask what the problem is ?
