The timer function in NS in Constant Bit Rate(CBR) traffic
generation works like this. After every interval it creates a new packet and
sends the created packet. For me what i want is, if i have created a packet
with sequence number 1, i send that packet and wait for
I have simulated wired-cum-and-wireless with ns-2.26
on Red Hat 9. In opt(adhocRouting) i use AODV.But when
i simulated it,it can't work well.Packets didn't send
to MN.But when i change into DSDV it can work.Do
ns-2.26 doesn't support for AODV?or are there any
false with my script.Thanks
Hi NS2 users,
Please someone Can help me about this subject:
How to know when a node receive a UDP-CBR packet from a emittier???
I am trying to simulate UDP server/client application.
The client will send the request and the server receives it and send it
back to the client and client receives it.
When i tried with Agent/UDP? I don't know send the message back to client.
One more, the client
In real 802.11b and 802.11g wireless cards the bit rate changes dynamically
depending on the channel conditions. If the card is working at 54Mbps and
is receiving no ACK's from the receiver it will automatically switch to a
lower bit rate. Modulations used by lower bit rates are stronger
I am waiting for a response.
I am encountering a problem with ns loss models...
The problem is:
The uniform / Markovian loss model works very well with UDP agent But when I
try to use these loss models with DCCP/TCPlike Agent it does not works
ns-2 does not offer native support for such phenomenon.
can have a look at the patch at www.reti.polito.it/fiore
realistic propagation and ARF support.

I am running the same simulations of ad-hoc network with ns2.26 and ns2.28 and
I get significant differences at delay measurements.
Especially when DSR is considered the differences are quite high.
Can someone verify these conclusions?
Is the implementation of DSR so
hello... need for some advice...
hello members... please teach me how to compute the delay for 10 packets at
the same times.
Hi Christos, Hi all,
I noticed also that TCP behaviour is different between the two versions
(ns-2.26 ns-2.28). I ran the same simulation on both versions and I
noticed that in ns-2.26 there is more dropped packet than in ns-2.28. I do
not know if this is a bug in ns-2.26 or not. Has any
thanks for the response.
But, i want the flow as client--server--client.
So, that i can able to find out the response time for the request.
Simplex will be trigger the request and response independently.
Is there way to give continous X request of N bytes? ie., parameters for
I have been looking for a solution on how to set a TX range for a Base Station
that is different (e.g. much larger) from other nodes in the network.
Unfortunately all the solutions I have tried (including ones already posted on

I wanna extend the CBR traffic generator? How do I go abt it? What the
the classes I need to change and what are the equivalent TCL object
classes to change?
I need to write and encoder_interface (Encoder Interface) for a VoIP

I have a question related to the receive function in dsdv.cc
If you take a look on the code it does the following:
1- It first checks if the node is the sender (src == myaddr_)
2- Then it checks if the packet received is a routing packet (src !=
myaddr_) (iph-dport() == ROUTER_PORT)
You can set parameter as follows:
set app [new Application/Traffic/CBR]
$app set rate_ 64000 ;#kbps
$app set packetSize_ 100 ;#bytes
You can get more details in ns manual.
