[ns] Validation tests fail after UMTS (EURANE) patch on ns-2.29.3

Hi, I have installed EURANE patch to ns-2.29.3 release on Fedore 5 core (kernel version 2.6.15, gcc version 4.1.0). Without the EURANE patch only some validation tests on test-suite-red.tcl fails that is the known problem with the Fedora core

[ns] 802.11 Auth

Hi, I need to simulate WLAN in infrastructure mode, but as I understand in ns2 mobile nodes donot make authentication /association as per IEEE 802.11. The association of a mobile node with BS is automatic. Please correct if my finding are wrong and there is a method to do auth/assoc. Also any

[ns] How to compile the modified ns in Win dows XP?

Hi, I install ns2.1b9a in Windows XP(without cygwin).After adding some new code(c++ and tcl code), how to compile it to make the new function resultful?Does anyone know the compile command? Thanks in advance! Regards Li An

Re: [ns] wimax ns-2 implementation

Hi There is no need to implement several channels. Since CID is carried in the WiMAX MAC header, it is enough to analyse this value when a packet arrives. Of course, you have to set it to the correct value when you send a packet. Sincerely, Alexander Sayenko (PhD) Senior Assistant

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

[ns] Mulitiple channel problem

Hello Everyone, I am having a problem simulating a wireless node with multiple interfaces and multiple channels per interface. Since the existing ad hoc routing protocols are designed for a single interface, how would i make them work on a multiple radio interface solution? can anyone with

[ns] Diffusion3 - Nodes Awaking

Hello. I'm doing a simulation using Diffusion3, and I want to construct a scenario where new nodes appear in the wireless network at a certain time in the simulation. How can I do that? Thanks.

Re: [ns] how to add delay factor bytes per second

Hi, Can't you use a time delay instead ? Maybe you can implement a custom queue which adds that overhead. It should not be so hard to do it if you create a subclass of Queue. Regards, Pedro Fortuna INESC Porto On 8/3/06, Muth S [EMAIL PROTECTED] wrote: Hi all, I need to add a delay

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

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

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

Re: [ns] problem with traffic and scenerio

Hi : I do have also the same problem. I don't know when segmentation fault happens. When we change the prtocol used in a code to another one (like DSR to AODV), sometimes it works properly and sometimes not. In addition, I created a scenario for implmenting aodv 2 weeks ago which was

Re: [ns] problem with traffic and scenerio

Hello, I am assuming you are using a *nix system It is some times simpler if you can locate the root cause of the segmentation fault. To do this, make the following changes to the Makefile in the */ns*-allinone/ns*/ folder. 1. locate the compiler command it will either be cc or gcc. change it
