مشکل در اجرای فایل های شبیه سازی شده بیسیم در NS2

[ahgrab]

سلام خسته نباشید

من NS2 تو محیط ویندوز نصب کردم با استفاده از cygwin ،همه چی درست نصب شده و کار میکنه اما فقط برا ی شبکه

سیمی جوا ب میده و برا ی بقیه اطلا جواب نمیده؟

NS هم این ورژن نصب کردم ns-allinone-2.34

چیکار باید بکنم ؟خواهش میکنم کمکم کنید.؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟

[aram_2]

خب از کجا می فهمید که برا سیمی جواب نمیده..بیشتر توضیح بدید

[ahgrab]

سلام خب فایل های که شبکه سیمی هستند و اجرا میکنه و جواب میده

اما برا فایل های بیسیم جواب نمیده؟

[ahgrab]

برا مثال این اجرا میشه

set ns [new Simulator]

#Define different colors for data flows (for NAM)
$ns color 1 Blue
$ns color 2 Red

#Open the Trace file
set file1 [open out.tr w]
$ns trace-all $file1

#Open the NAM trace file
set file2 [open out.nam w]
$ns namtrace-all $file2

#Define a 'finish' procedure
proc finish {} {
global ns file1 file2
$ns flush-trace
close $file1
close $file2
exec nam out.nam &
exit 0
}

# Next line should be commented out to have the static routing
$ns rtproto DV

#Create six nodes
set n0 [$ns node]
set n1 [$ns node]
set n2 [$ns node]
set n3 [$ns node]
set n4 [$ns node]
set n5 [$ns node]

#Create links between the nodes
$ns duplex-link $n0 $n1 0.3Mb 10ms DropTail
$ns duplex-link $n1 $n2 0.3Mb 10ms DropTail
$ns duplex-link $n2 $n3 0.3Mb 10ms DropTail
$ns duplex-link $n1 $n4 0.3Mb 10ms DropTail
$ns duplex-link $n3 $n5 0.5Mb 10ms DropTail
$ns duplex-link $n4 $n5 0.5Mb 10ms DropTail

#Give node position (for NAM)
$ns duplex-link-op $n0 $n1 orient right
$ns duplex-link-op $n1 $n2 orient right
$ns duplex-link-op $n2 $n3 orient up
$ns duplex-link-op $n1 $n4 orient up-left
$ns duplex-link-op $n3 $n5 orient left-up
$ns duplex-link-op $n4 $n5 orient right-up


#Setup a TCP connection
set tcp [new Agent/TCP/Newreno]
$ns attach-agent $n0 $tcp
set sink [new Agent/TCPSink/DelAck]
$ns attach-agent $n5 $sink
$ns connect $tcp $sink
$tcp set fid_ 1

#Setup a FTP over TCP connection
set ftp [new Application/FTP]
$ftp attach-agent $tcp
$ftp set type_ FTP

$ns rtmodel-at 1.0 down $n1 $n4
$ns rtmodel-at 4.5 up $n1 $n4

$ns at 0.1 "$ftp start"

$ns at 6.0 "finish"

$ns run

سلام یه سوال.
برای نوشتن به زبان tcl برای ns2 از چه محیطی میشه استفاده کرد که شبی مثلا ویژوال سی شارپ خودش کتابخونه هارو داشته باشه و تو پرانتز گذاری کمک کنه

[princoo]

تو هر محیط متنی می تونید بنویسید فقط پسوند فایل tcl باشد

[pencel_2004]

salam man ham daghighan moshkele shoma ro daram. baraye shabake simi ns2 be khobi suport mikone , baraye shabake bi sim ham javab mideh vali kami zaif hast.
ageh dar in rabete betonim beham komak konim khaili khob mishe. man az ns-2 bekhatre prozham estefadeh mikonam vase hamin baraye tahvile prozham ziad vaght nadaram .
emaile man pencel_2004@yahoo.com hast ye email behem bezan
taaanx.................

[pencel_2004]

پس چرا کسی جواب نمیده!!!!!!!!!!! مدیر لااقل تو جواب بده............!!!

[aram_2]

یه با دیگه مشکل و خطا رو بذار.کد tcl رو نذار فقط خطاشو بذار.
