Hello everybody!
I am trying to implement multi-interface support for wireless nodes, using the
Module-based Wireless Node: http://www.q2s.ntnu.no/~paquerea/ns.php
Has anyone worked on it? Does anybody know if (and where) I can find some
example tcl scripts?
Thanks in advance,
Spyros

Dear all,
We have seen a lot of requests about the possibility to extend the NS-2
framework to support multiple interfaces. Although there is some
information available, according to the messages that have been sent to
this list, it seems that a more thorough description may be required.

Ramón,
I have been reading your how-to and as your statements and concerns are
quite similar to a subset of those we presented last year in [1], you
might find interesting reading this paper.

Node for ns-2", in Proceedings
Hi there,
Is the coding working for 802_15_4 (LR-WPAN)?
Hi, I will be also working on multi-interface support for wireless nodes. I
am still in the very beginning stage though. I would also appreciate if any
materials in this area could be shared. Thanks.

great job as far as i can see.

thanks for pinpointing the error! Somehow I made a mistake when copying and
pasting the code to the file.
The correct procedure would be the following one (note that the arptable_

change all arptable_ into arp

Hello Nguyen,
in that file you should change all the times that nextX_ and prevX_ appear.
These are used to manage the mobile nodes' lists. Instead, you have to use
an array, according to Listing 4.1, so you must refer to the correct array
element by using the appropriate index.
To sum up: do
hi,
i'm trying to user mutliple interfaces with the adhoc routing agent
"noah" - which stands for "NO AdHoc routing". i use only one mobile
node, and some basestations with foreign agents, an home agent and a
corresponding node.
as noah doesn't need a routing table, i use a map for storing the
i found out that a missing line in ns-mobilenode.tcl caused that strange
behaviour.
since i correctly added
set sndT [cmu-trace Send "RTR" $self]
the traffic seems to be fine, except that the wireless packets don't
appear in NAM anymore.

Hello Tim,
I've not personally used the NoAH extension myself, so I cannot completely
figure out which would be your problem.
Nevertheless, why do you use the prev_hop? I don't see the difference here
between NoAH and any other routing protocol. If you have received a message
from a base stat
Hi Tim,
I should have read this message before, sorry for the spam.
Can you clarify where did you add these two lines?

Nguyen,
I try in this post to sum up and explicit the main differences between
the approach proposed by R.Aguero et al. in their how-to and ours with
the MW-Node. I hope it helps you choosing what better fits your needs.

Hello,
I wanted to know if anyone has done the changes as required by the
documentation of ramon for multi interface support in ns2. I have made all the
changes but i am not sure about the changes to be made in the routing protocol.
Kindly help in this regard

Hello Laurent, Nguyen, all,
Thanks for the discussion.
In my opinion, it's sort of difficult to compare both approaches. It seems
that the work that Laurent has done is quite much more comprehensive and
detailed, since it uses a different approach from what the current ns-2
architecture uses
hi,
i guess there is something wrong on ns-lib.tcl
for some reason "chan" is set as a usual variable. if you follow the
modifications of the document correctly, "chan" is used as an array in
case of mutliple interfaces.
the problem might hide somewhere in here:

Hello,
I have not declared them in common/packet.h. The only place I put them
in is aodv.h (as in the document). I think this problem came from other
place and I should read the document carefully but now I don't know yet.
Thank you very much.

Ok, I'm glad that you solved the problems related to the extension. I don't
really know how to address these warnings or whether they are relevant (at
least the virtual destructor one should not).

My problem is that I declared nIfaces, targetlist and ifqueuelist in the

Hi Shahatha,
As we say in the report we didn't use aodv, so we really appreciate that

own experience on AODV.

personally used that much) and this is
