[ns] how to call the mac layer information from routing layer?

[耿蓉]

In my simulation ,i use dsr routing protocal,and in the process of finding 
routes, need to use mac layer(mac 802.11)'s information.　And the same , in dsr 
need to use ifq of ll layer. How to do? Thanks a lot. 　　　

[ns] segmentation fault

[lewapryb]

Hi everyone!
At last managed to install ns-2.1b9a from:
ns-allinone-2.1b9a-gcc32.tar.gz

Then I wanted to add gprs patch but it is not original made by Richa
Jain but a later version (they wrote it's better :) )
It is from: gprs-gcc32.tar.gz

I made as they wrote in readme file and ./install again.
And - wow - ns is working!!!  but gprs not

I still got the same: 
num_nodes is set 10
Segmentation fault

What can I do
anyone cope with that GPRS

[ns] ns routing algorithms understanding

[Augusto Castelan Carlson]

Hi!

I'm reading _The ns Manual_. When they talk about routing in chapter 28, it says
that Static and Session routing use Dijkstra, and that Dynamic routing uses
Bellman-Ford.

Where are these algorithms implemented and refered in the ns source?

I tryed to find them without success. I made a research in the mailing list
archives, but found nothing helpful.

I'm interested to have a good understanding of the already implemented
algorithms and manipulate them. With this understanding I can become familiar
with ns source code and implement my own algorithm and maybe, my own protocol.
I also have read the FAQ, Marc's tutorial and the document "Implementing a New
Manet Unicast Routing Protocol in NS2", but when I compile the source files, I
get many errors. As I'm interested in tradicional routing, I'm a little bit
distrustful to become confused with tradicional routing and wireless routing.

Thank you very much in advance.

Cheers,

Augusto

[ns] WF2Q+ and so on..

[Daniele]

hi all,
is there a simple way to have a WF2Q+ scheduler in the diffserv environment?
I'm using ns-2.29.
I tried with the Sergio Andreozzi's patch either in 2.1b8a and 2.29
but in the first it doesn't compile because the compiler is quite
different (g++ 3.4 vs g++ 4.0) and in the second as well it doesn't
work.

Advices?

Daniele

Re: [ns] researches on ad hoc

[Güzin Ulutaş]

Hi Cemal,
I can suggest you something that I learned. First of all, you must 
understand what is the interaction between the otcl and c++. When you 
use which of one. And then "implementing a new manet routing protocol 
" is a good 
tutorial. This tutorial suggest you, some chapters from ns manual that 
must be read before reading this document. I think, you must observe 
dsdv and aodv codes. First of all, it can be hard for you, but you must 
be patient. Have a good luck.

[ns] researches on ad hoc

[j e]

Hello!!!
  I am working with ns-2.29 and doing researches on ad hoc network I am 
working with DSDV and DSR protocols. I am doing simulations and reading Altman 
& Jimenez ns. I would like to read deeper, couse this book is not enough for 
me. could you help me to find deep informations about them.
  tahnks in advance.

hi all,
   
  I could compile all the scripts and source files, but an error message will 
appear when i run the tcl script.  That is happen in ns-lib.tcl.  Is anyone 
could give help on this? 
   
  [code omitted because of lenght]
  :wrong # args: should  be {Simulator instproc name args body}
 (class instproc line 1)

  Thanks.

Re: [ns] Interval for HELLO message

[choong cheong]

Hi guzinu,
   
  I'm really appreciated for your kindly reply and information.  Thanks a lot.
   
  The round is one hop.  I'm implementing a token ring module.  Round length is 
meaning that the token visited how many nodes in one round. The token maybe 
visited multiple times in one round.   My problem are - I'm implementing 3 
graphs, which are average byte vs hello interval, average time vs hello 
interval and average round length vs hello interval.  I can't get the expected 
values for those graphs.  Can i get those values from newtrace format output 
file?  Can i say that the sequence number is equal to the round length?  How to 
get the average time and average byte?  Can i assume the average packet size is 
average byte?  Why all the output values are equal when increasing the value of 
interval?
   
  Actually , i haven't get the token ring module work yet, but i try to get the 
output values from AODV and DSR routing and do the comparasion, but i believe 
that the theory should be correct.  The average byte, average time and average 
round length should be drop when the interval is increase, because it will take 
a long time to send the hello message.  
   
  I'm really appreciated you if you can help me for this.
   
  Many thanks.
   
  Best regards,
  Choong Wing Cheong
   
   
  I have asked so many questions here.

What do you mean with "round" ? you can explain more clear, maybe I

[ns] Double Covered Broadcast (DCB) code for NS2 simulator

[Srinath Mandalapu]

Hi 
   
  Has anyone aware of the implementation of DCB (Double covered broadcast) 
algorithm for NS2 simulator? This algorithm is described in Double-Covered 
Broadcast (DCB): A SimpleReliable Broadcast Algorithm in MANETs - Wei Lou and 
Jie Wu. (http://www.ieee-infocom.org/2004/Papers/43_1.PDF).
   
  If anyone has already implemented it, can I have access to the code ?
   
  Thanks
  Srinath
