[ns] voip problem

hello , now i want to add a voip application to ns2.30, and i use the source code in the "simulating playout scheduler for voip ",but i don't understand what is the *.bit file and *.vuv file which i need to have before i start the 1VOIP_802_11.tcl help me please!!! thanks a lot!!! ___

Re: [ns] VoIP

Hi Since many VoIP codecs send data at the constant rate, you can use normal UDP/CBR application to simulate VoIP. You have to set appropriate parameters so that the rate and the packet size correspond to the codec you use. Sincerely, Alexander Sayenko (PhD) Assistant Telecommunication laborator

[ns] VOIP encoding

I am trying to simulate voip using ns2, I have a problem with creating voice payload, not the whole packet but only payload. Does anyone know or have some piece of code would be wonderful for me or links where I can study it. Thanks in advance. smble

[ns] VoIP traffic Simulator

Hi, Does anybody know an existing VoIP simulated Application existing on NS2? I am ready to develop it myself, however, most of my questions has no been answered.

hello users, i'm trying to simulate voice over ip over wlan 802.11 and also web traffic over wlan and compare the delay of the voip and ftp packets through the lan i would like some help thanks Do you Ya

[ns] VoIP Traffic Generator

Hello All I have followin two questions: 1) Can anyone please tell me how to simulate VoIP traffic generator using G.729 codec. I read somewhere on the mailing list, that we have to modify CBR traffic for that, but that was in archives and I am not sure, if we already have now G.729 support as tra

[ns] VoIP with VAD

Basically, in continuation t o my previous mail, I am trying to simulate VoIP application with Silence suppression. So,has anyone done that before or if anyone has any idea, can you please guide me.?/ Thanks in advance -- Thanx Shaili Desai Master's Candidate Telecommunications and Management Un

[ns] VoIP in ns

Hi everyone; 1. Please tell ma how Voip traffic should be created in ns 2. i suppose it is a simple cbr application? 2. how to get statistics on delays and packets loss in MANETs with ns2 i am using ns2.31 Thank you,

[ns] VoIP Packet Size

Hai all, I would like to make a voip packet with the RTP agent and CBR application. I try to set the payload size on CBR for 33bytes, and the packet size on RTP agent was 40bytes+33bytes(payload)=73bytes. When i run the simulation the trace file shows that the CBR packet was 210bytes size. How can

Re: [ns] VoIP traffic Simulator

VoIP is basically just UDP packets encapsulating RTP packets with the voice data inside, all you should need to do to simulate a VoIP stream is set the correct packet size and frequency that the packets are sent out and that would simulate a stream, all of which can be done easily inside your t

Re: [ns] VoIP traffic Simulator

Hello, I've been using Application/Traffic/Exponential as a traffic generator on top of Agent/UDP. It's not perfect, because, for instance, I specified 8Kbit data rate, but often I only see 5 or 6Kbit/s passing through... but maybe i'm doing something wrong Pedro Fortuna INESC Porto On 8/4/

Re: [ns] VoIP traffic Simulator

Is it necessary to consider the correlation between UL and DL voice traffic? Or we simply assume UL and DL are independent traffic stream both generated by Application/Traffic/Exponential? I am simulating VoIP in 802.11 networks, where UL and DL compete for the same channel. Thanks Quoting Pe

Re: [ns] VoIP traffic Simulator

I assume that there's a correlation, because two people do not talk exactly at the same time. They usually talk and then listen. Thus, one flow periods of idleness usually correlate to the other flow's periods of burstiness. Maybe the best way to model that is with a single on/off source, but I do

Re: [ns] VoIP traffic Simulator

If you want to simulate VoIP traffic you could also use the Paretto generator, I think it will simulate bursty VoIP more precisely than Exponential. Douglas Nascimento - UFRGS Quoting Pedro Fortuna <[EMAIL PROTECTED]>: > > I assume that there's a correlation, because two people do not talk > ex

Re: [ns] VoIP traffic Simulator

Thanks for the tip. I've even found an example on a previous msg of this mailling list: " ... set udp0 [new Agent/UDP] $ns attach-agent $n(1) $udp0 set null0 [new Agent/Null] $ns attach-agent $n(2) $null0 $ns connect $udp0 $null0 # create 16 Paroto On/Off source traffic for {set i

Hi all, I'm looking for VOIP simulation example in ns2 using normal cbr traffic, if anyone has any idea how to setup it, appreciate if you can let me know...tq..

[ns] VoIP model for NS-2

Hi everyone.Pls I'm researching on an efficient VoIP model for NS2. I want to carry out some simulations relating to VoIP Quality of Service (QoS). I was thinking of the Poisson distributed model but I could really use any input from anyone concerning this issue. I hope someone replies soon.Thanks

Re: [ns] VoIP traffic Simulator (off-topic)

Because, in that particular example, the node is just the sink of the VoIP traffic. It does not send packets in the reverse direction. If bidirectional VoIP flows was desired, then you would need an udp0 in one direction, and another in the reverse direction. Something like: set udp0 [new Agent/U

[ns] VoIP script or simulation -mine attached

Hello All I am tryin to do VoIP simulation in NS with Wimax NEtwork. Can anyone help me getting a VoIP script. I have written one of my own,but it gives me output where there are only all send packets. Can you suggest anythng for the same,or if anyone has any voip simulation script before, can y
