[ns] Tracegraph installation Problem under Windows
Hello everybody: I installed tracegraph under windows according to this instruction: Installation instructions on Windows 1)Download tracegraph and mglinstaller from the page make sure it is windows version http://diament.ists.pwr.wroc.pl/~tracegr/tgform.html 2)unzip tracegraph202.zip to say, C:\ 3)execuate mglinstaller.exe, when it asks for directory name, enter C:\tracegraph202 4) add C:\tracegraph202\bin\win32 to your enivronment PATH 5)how to add to environment PATH?? right click on Mycomputer and select properties From properties select Advanced tab Select environment path variables Select PATH and add your path to it Thats it tracegraph is now ready!! This is the procedure i followed while installing tracegraph on both windows and linux (if you dont have matlab installed on your machine.) but I get this error : The application has failed to start because libmmfile.dll was not found. Re-installing the application may fix the problemwhen I want to run trgraph. I need to add, I already have matlab7 installed and it's path is : C:\Program Files\MATLAB704\bin\win32. I hope somebody can help me with error. Thank you, Sara _ Got something to buy, sell or swap? Try Windows Live Expo ttp://clk.atdmt.com/MSN/go/msnnkwex001001msn/direct/01/?href=http://expo.live.com/
[ns] energy-model in ns-2.29: sendDown
Hi All,
I have a question regarding the energy model and wireless-phy in ns-2.29.
In the function WirelessPhy::sendDown(Packet *p) we see the following code:
v1.23
http://nsnam.cvs.sourceforge.net/nsnam/ns-2/mac/wireless-phy.cc?revision=1.23view=markup
207 if (em()) {
208 //node is off here...
209 if (Is_node_on() != true ) {
210 Packet::free(p);
211 return;
212 }
213 if(Is_node_on() == true Is_sleeping() == true){
214 em()- DecrSleepEnergy(NOW-update_energy_time_,
215 P_sleep_);
216 update_energy_time_ = NOW;
217 218 }
v1.22
http://nsnam.cvs.sourceforge.net/nsnam/ns-2/mac/wireless-phy.cc?revision=1.22view=markup
190 if (em())
191 if ((em()-node_on() != true) || (em()-sleep())) {
192 Packet::free(p);
193 return;
194 }
It seems rational to me that we should also free the packet if the
node is on and sleeping (as in v1.22).
According to v 1.23-v1.25, the wireless-phy can send a packet down, even
if it's sleeping?
What is the rationale?
Best regards,
Pieter

[ns] ns ftp
From what I see there is no ftp implementation in ns, more precisely what seems like ftp application is a tcl Application/FTP object that the only thing it does is to send packets through a tcp connection. So is there a real ftp implementation that complies to the standard? ggeorgak

Re: [ns] ns ftp
I am sorry for the aggresiveness of my mail. The free implementation is too unreliable for what I am trying to do as I want very accurate results. The use of emulation is possible but still there are better ways to do it (PlanetLab). As for the open-source spirit you are completely right. I apologize again, it was in the spur of the moment. ggeorgak On Wednesday 23 August 2006 16:56, you wrote: You have to understand that not everyone has the same requirements you have. Very few ppl would need a complete and rigorous implementation of FTP in NS.

When you do some simulations, you do not need to implement everything, you just need to figure out what is important for your studies. There's two things that come to mind that you could probably do. 1) adapt a free implementation of FTP to a new Application/FTP source and sink 2) use real FTP traffic (NS2 can be made to bridge between two real life FTP applications). I'm not saying that those are easy to accomplish, but they are certainly feasible. As for the unmaintainability of NS, I share your concerns, but there's nothing we can do except to contribute. That's the spirit of open-source. In the meanwhile, NS3 is being planed and will be available some day. Best Regards, Pedro Fortuna INESC Porto

can anyone please tell me how to send only 2 tcp packets in a simulation. these 2 pkts must also be rxmitted if nessecary. thanks in advance
Re: [ns] I have a problem in simulation .... while the compilation is okay
I reckon a new event ID is assigned every time you schedule an event. You
can create a new packet and have it sent down in Mac.

One possible reason to the Event UID not valid! problem is that the

scheduler.cc, and see if that helps.
