Dear Mohit P. Tahiliani
thank u for this help. but i am getting one problem. whenever i am setting different channel to the node few cases i get segmentation fault. can u tell me the reason.
here i am giving one example--
$ns_ change-numifs 3
for {set i 0} {$i < 100} {incr i} {
$ns_ add-channel 0 $chan_(0)
$ns_ add-channel 1 $chan_(1)
$ns_ add-channel 2 $chan_(2)
set node_($i) [$ns_ node]
$node_($i) random-motion 0
}

$ns_ change-numifs 1
for {set i 100} {$i < $val(nn)} {incr i} {
set f [expr $i-100]
set in [expr $f%3]
$ns_ add-channel 0 $chan_($in)
set node_($i) [$ns_ node]
$node_($i) random-motion 0
}
i am using 300 node where 0 to 99 node has 3 channel and other 200 node few has chan 0 few has chan 1 and few has chan 2. the mode function is for this distribution. plz reply me quickly.

Hello sir,

how to calculate congestion level in AODV?

please help me...

best regard
Khozaimi

@Khozaimi - Search for "IFQ" in the 5th column of the trace file which is generated by running the TCL Script. This indicates that the packet has been dropped because of congestion. "Packet drops due to congestion" is one metric by which you can find out the congestion level. Alternatively, you can also use link utilization to do the same.

Hope it helps.

hello sir
is this revised patch only for AODV protocol?

im using ZRP protocol
and its not fix anything i think
can you explain to me please sir?
thank you

is this patch will work for ns2.35

hello sir,
I am a student of S.I.T Tumkur, sir can u send me the exectuing ns-2 code for Adding Interface with model graphs and output.........please sir fast.......

Thank you so much for this patch.

I have a small problem after trying it, the command "node" is not passed to the c code of AODV. I mean command method doesn't receive "node" command and the index of the node is not assigned probably

Thanks

Dear Sir,

I added multi-channel support in ns2 according to "Adding multiple interface support in ns2" tutorial. Then I found this website.
I am currently having problem for multi-channel support for mobile node. It works fine for static node. The problem is as follows.
Program received signal SIGSEGV, Segmentation fault.
0x000000000069f926 in MobileNode::X (this=0x18dc1) at common/mobilenode.cc:619
619 return X_;

I would like to know why this problem happens.

I also would like to know the problem you found in mac-802_11.cc and its solution.

I am looking forward to your reply.

Thank you.
Best Regards,
Cherry

set chan_(1) [new $val(chan)]
set chan_(2) [new $val(chan)]


$ns_ change-numifs 2
$ns_ add-channel 0 $chan_(0)
$ns_ add-channel 1 $chan_(1)

set node_(0) [$ns_ node]
$node_(0) random-motion 0

set node_(1) [$ns_ node]
$node_(1) random-motion 0

set node_(2) [$ns_ node]
$node_(2) random-motion 0

$ns_ change-numifs 2
$ns_ add-channel 0 $chan_(0)
$ns_ add-channel 1 $chan_(2)

how to install multiple ns-2 versions on ubuntu 12.04

Hey Mohit.
I was wondering if this patch would work with the latest version of NS (ie. 2.35). If not, could you please suggest another alternative because adding the patch to 2.33 involves lots of inconsistencies. Furthermore, its a headaches trying to figure out how to make this work. I'm currently working on something very important and I need multiple interfaces to go ahead. So, a quick, speedy reply would be very much appreciated and I would be so very grateful. Thanks in advamce.

Hi Sir,
How can we obtain number of interface in c++ part ? Thank you.

Good Day Sir,
I have the multi interface functionality to NS-2.35, I want to send traffic received from one interface to the other (2nd) Interface.
Can you please guide me what is the exact plan of action.

As far as I think,I'll need to do some changes in the Protocol file, e.g. AODV.*

Waiting for your response.

Thanks in advance

Sir,
I have a question regarding dmux_->recv(p,0); in aodv.cc
It seems that it is never getting executed. Then, how data packets are received by the destination?

Waiting for your reply,
