[ns] Graphical User Interface for NS-2?
Dear all ns users, I am third year student doing my project using ns-2 i have only 2weeks left to complete and hand-in my project. To finalise my project I was thinking of adding a graphical user interace to it. I wrote my code in tcl but I don't know what software I need to use to do the GUI. Hence, I kindly ask you all if you can reply to me with ideas on how to add the GUI or if you have any link(of a tutorial) with an example on how to do it, i would really really appreciate it! Anticipating to hear from you all, I would like to thank you very much in advance for all your help!!

[ns] TraceGraph Helpppppp!!!
Dear all, I was trying to use trace graph to plot graph for my simulation. However, it seems like there is something i have not understood about it. Everytime i try to plot the graph say for one of my tracefiles and i do trgrpah name of file on the terminal it does launch the tracegrpah window but it doesn't plot anything. Now what i have done is create a .ip file but what i am not sure about is do i need to write my own awk file to make it plot a graph say for the delay or throughput. I am sure you can tell that i am way losttt so please please any help on tracegraph would be appreciated. I would be more happy if some one can tell me the basics in plotting a trace graph or the things i need to do or don't! Anticipating for your kind cooperation, I would like to thank you very much thank you!

[ns] Trace Graph Help Neeeeeded so badly!!! Please(100X)
Dear all, i have installed trace graph i am using Linux-Ubuntu! i found some sample trace graph files i wanted to run it and see what it does and understand what it is doing and hence move on from that and do my own. However, i am not sure what command i have to use to make it run on the terminal a friend sent me this link http://tagus.inesc-id.pt/~pestrela/ns2/tracegraph.html not sure what it is really trying to say or what i have to do when it comes to generating a .tr.ip file. Another thing i am finding hard to understand is do i need to download trconvert as well? My project was going fine until this point i only have few weeks left to finalize my project and i am really stuck so every little help with trace graph is more than welcome and appreciated. I have read on a forum that understanding trace file itself takes up to 3months and i don't have that long so please please help as much as u can !! Anticipating for your prompt reply, I would like to thank you all in advance.

[ns] Help pleaseeee!! i am new 2 NS
Dear all, I am using NS-2 to do my final year project. It is my first time to use both NS-2 and TCL. I need to do random generation for my simulation but I don't know how to do that! and I couldn't find any kind of help on that please please do help me as i have only few days left to complete the first part of the project that is running my wireless simulation for randomly generated number of nodes. Any help will do! Hoping to hear from you all, I would like to thank you very much in advancee!

[ns] building simulator using MAC 802_15_4! help needed!
Dear all,
As my name implies i am new to both ns and tcl. I am trying to develop a WSN
simulator using zigbee protocol instead of MAC 802.11 as my final year
project. I was trying to give the user of the simulator to choose to enter
the number of nodes so before getting my hands dirty with all the coding i
decided to run a code which has been written by someone else. I have been
told that the code does work however while running it i kept getting the
following error message
[EMAIL PROTECTED]:~/Documents$ ns wireless1-orig1.tcl
num_nodes is set 1
INITIALIZE THE LIST xListHead
Agent/TCP B0 with pktsize 1500 flows from Node0 to Node0
Starting Simulation...
Segmentation fault
I would really really appreciate all the help i can get as i need to get
this code working which means i will understand what i am doing or supposed
to be doing. For your reference and subsequent correction or comment or
explanation here i have attached the code.
