[ns] SOLVED! debugging ns-2 in eclipse
Ok so after spending a lot of time on trying to debug ns in eclipse, I found the solution! to give a step by step guide: after installing ns and eclipse, first take the steps given in the following site : http://blog.karthiksankar.com/ns2-eclipse/ except that don't change the make file after doing this you should be able to build and run your ns and tcl file without error seeing the % command or the output of your tcl now to be able to debug ns in eclipse, go to your ns-allinone/ns-2.3x/Makefile.in file and change the following: 1. change CCOPT= @V_CCOPT@ On Tue, Jun 14, 2011 at 10:47 AM, ÞÕÇÏ Úíäì Ýì ßá ãßÇä mohammed teto...@yahoo.com wrote: unfortunalety, i dont know how to debug c++ , please if you know inform me , thanks alot --- On *Sun, 6/12/11, Ella Taha ella.t...@gmail.com* wrote: From: Ella Taha ella.t...@gmail.com Subject: Re: [ns] debugging ns-2.33 in eclipse To: ÞÕÇÏ Úíäì Ýì ßá ãßÇä mohammed teto...@yahoo.com Date: Sunday, June 12, 2011, 9:11 AM go to run -- run configurations and then choose the arguments tab and inside the program arguments add the address of your tcl file for example: /home/ns-allinone2-33/ns2-33/aodv/file.tcl do you know how I can debug the C++ files?

Re: [ns] accessing queue length in 802.11 MAC
Hi, anyone as tested this method?
I've insert following code in mac-802_11.cc in recvDATA() but i've

int pkt_in_q = 0;

Dear guys,
I tried to access queue length in MAC. So I wrote

When I run the simulation us gdb, segmentation fault occurs. I shows

Does any one know how to deal with this problem?
Thank you very much,

[ns] throughput too high plz help
Dear all, I have a logical question plz: the FTP/CBR application in my simulation.tcl have paquet size set to 1500 and the interval set to 0.1s. following my logic, I should obtain a maximum throughput = (1500 * 8)bits /0.1s = 120 000 bits/s or 120Kbit/s or my file awk calculate the throughput = 163.84Kbit/s 120 Kbit/s . is this wrong? or can be 120.Kbit/s what you can say about the value of 163.84 can be a correct value or never ?? plz waiting your answer -- View this message in context: http://old.nabble.com/throughput-too-high-plz-help-tp31841932p31841932.html Sent from the ns-users mailing list archive at Nabble.com.
[ns] Eliminating wireless losses and propogation delay
I am trying to model 802.11 network without any wireless losses and without any delay. I have made following changes but results are not convincing. I have used free space propagation model and made following change in propagation.cc file: Instead of calculating Friss free space equation, I have directly returned 'Pt' (Power at transmitter) for the function to depict as if power has not been affected at receiver resulting in loss less model. In channel.cc, I have hard coded propdelay=0 at all places to eliminate propagation delay. With following modifications, i placed 10 nodes close to each other and ran 5 different flows of same type between 5 pairs. I expected to see same throughput on all nodes since there is no delay involved (so nodes perform irrespective of their position) and no loss is present but results were totally different with large asymmetry. Can someone plot a better idea of eliminating delay and losses? Also is it a wrong assumption in such a scenario to expect same throughput?

[ns] VANET, Ad-hoc broadcast protocol
Hello All, I am currently using DumbAgent as routing protocol to simulate VANET scenario and the Flooding mechanism is written within ping Agent code. Can some one suggest me any other VANET or Ad-Hoc broadcast protocol which is implemented in NS2? I am looking for any of the broadcast method it can be a probability based method, Area based or Neighbor Knowledge Method. Thank You Rakesh
[ns] Fwd: ns2 wpan simulation: Bug?
I am working on ns2 and need to simulate a simple application on lines of
ping. I'm using the ns2.34 build and it comes with the wpan module. When I
tried to test the application with a ping agent. It throws the error,

i get the following error when i tried the olsr patching from masimum Installation of otcl seems incomplete or can't be found automatically. Please correct the problem by telling configure where otcl is using the argument --with-otcl=/path/to/package (perhaps after installing it), or the package is not required, disable it with --with-otcl=no. after i configure it what should i do ?
[ns] pls help!! [conditional break in scheduler]
I'm using ns2.34. I'm getting event uid not valid error on running a tcl script. I created a ping agent as described in mark greis tutorial. It works fine with 802.11 but doesn't work with 802.15.4 and throws scheduler event uid not valid error. Does anyone know why this is occurring? Please let me know, how to know who dispatched the event. I know the event id. What are the specific lines (for conditional break) that need to be added to scheduler::schedule() to find out who scheduled that packed or in dispatch() to find out who dispatched it. Please help, I'm stuck here for last 8 hours. :( Regards, Devashish Sethia
