When I save xgraph window in postscript file, I get black-and-white graph. Does
anybody know is there a way to get colored graph in postscript (the way it
appears on screen)?
Thanks in advance

Dear P.Navaratnam,
I have the same problem , Have you solved itplease let me know if you
overcome it.
According to me:
I select the shadowing model as propagation model for wireless link. In this
model you can specify the loss ratio ( just read chapter 18 in ns-doc.pdf file)
if you solve
Dear NS users,
A couple of days ago I requested for Slotted Aloha and

Hallo All,
I am new to ns-2 simulation. I am simulating the
mac_802.11. I have created a dummy mac_802.11. I want
to run a simple tcl for this mac just to get the
information of sender id and receiver id in the
screen. Which code of the TCL script shall i modify.

Assuming I have three wireless node, I want to set
Node0 power ON at 10s (in other words, deploying in network)
Node1 power ON at 20s
Node2 power ON at 30s
But I've tried it in TCL code and its seems that it can't support a =
function like this.

Hello every:
There's my question about WLANs' operation.
In one BSS depicted as follows:

A and B are both mobile station and each radio range can overlay another
station. AP is the access point.
A has some data need to be send towards B. Do these messages need be relay
Hello Qadous,
I have used the tcl script below to test the error modeling. I am using
ns-2.29 and when I increase the value of rate_ from 0 to 0.05 I get more
duplicated packets, and collisions, which is a result of transmission
errors.
>I used the following command to specify the Error mode
Hi,
Classifier works on the node entry point. Each packet which is
received by the node is classified and accordingly it is either forwared to
the port demux or next link. So does the same classify works for all the
node ? Can i access node-id (or address) from the classify function? If
so

HI friends,
As we know CBR connection use an option type packet/sec to be
sent. Is that means they are sent at regular interval. i.e. 4 packet/sec means
it will send the packet at regular interval of .25 sec.
But i think it is not the real world communication.
For the second bug, check this link:
http://www.dei.unipd.it/wdyn/?IDsezione=2435
For the third bug, I think you modified the Mac-802_11.cc/h file somehow. I
think you introduced a new type of packet having the same type as
MAC_Type_Control. Check the types and the subtypes of your packets and al

Hi all ,
I want to get the rooting table of my simulation
and I don't kwow how to do this

You can look at the number of packet of type -P dsr sent
compare with the number of data packet (cbr or tcp) sent.
All of this info is in the trace file.

Hi Amel,
To get the routing table on each node
1. Find out which is the routing algorithm that you are using in your
simulation.
2. In the code corresponding to the implementation of that routing
algorithm, find out where is the routing table structure defined and what
is the structure.
3. Write

In the file aodv.cc, there must be a line

Just uncomment this.
If it not there, add the line

secondly i am getting less e2e delay too in case of DSDV?
