[ns] Implementing TORA in NS-2.34
Hi All, I tried simulating TORA in NS-2.34 for 20 nodes. For some time of execution i receive the output as below and than suddenly it shows Segmentation fault: node 165506090 received `UPD` from non-neighbor 17 node 165506090 received `UPD` from non-neighbor 17 node 165506090 received `UPD` from non-neighbor 17 node 0 received `UPD` from non-neighbor 1 node 0 received `UPD` from non-neighbor 1 node 0 received `UPD` from non-neighbor 16 node 0 received `UPD` from non-neighbor 16 node 0 received `UPD` from non-neighbor 16 node 0 received `UPD` from non-neighbor 16 node 0 received `UPD` from non-neighbor 5 node 0 received `UPD` from non-neighbor 5 node 0 received `UPD` from non-neighbor 5 node 0 received `UPD` from non-neighbor 5 node 0 received `UPD` from non-neighbor 5 node 0 received `UPD` from non-neighbor 5 node 0 received `UPD` from non-neighbor 5 node 0 received `UPD` from non-neighbor 5 node 0 received `UPD` from non-neighbor 5 node 0 received `UPD` from non-neighbor 5 node 0 received `UPD` from non-neighbor 5 node 0 received `UPD` from non-neighbor 5 node 0 received `UPD` from non-neighbor 5 *Segmentation fault* Can anyone suggest some way to solve this?

Re: [ns] Implementing TORA in NS-2.34
Dear Rahul Sharma, Segmentation Fault is a very common problem faced by NS2 users. It has to do with memory such as trying to access an address that cannot physically be addressed, thus an exception has been called. It can happen either in C++ side or at TCL side. The below looks like happening from C++ side to me. Thought the problem is very common, unfortunately the cause of the Segmentation Fault are very wide. It takes more than providing couple of preceding error lines to solve it. The right way to handle a Segmentation Fault is by debugging the code. To start with, if your simulation scenario involves 50 nodes, see if you could replicate the problem in the smallest possible number of nodes to simplify your debugging process. For C++ debugging you can use GDB or even putting simple printf lines around node 0 received `UPD` from non-neighbor 5 lines to see if the change of variables, memory allocation and function calls are done per your need. It will take some time to understand how GDB codes work for first time user and a certain amount of troubleshooting effort., once you get used to it, it will be easy. After finding where the abnormality occur, work your way up the code to know what caused the abnormality and rectify the problem. Its very rare another person could able to help you to solve Segmentation Fault without looking at all the codes. Good Luck. rgds Saravanan Kandasamy On Fri, Jul 6, 2012 at 9:58 AM, Rahul Sharma wireless.ra...@gmail.comwrote: Hi All, I tried simulating TORA in NS-2.34 for 20 nodes.

Re: [ns] voice traffic in wireless network.
Hi, Does anyone knows how to simulate voice traffic for 802.11 network. How is the voice traffic created? Please help, urgent.

Re: [ns] NS2 Visual Trace Analyzer
Hi ns users, I've finally made a blog about NS2 Visual Trace Analyzer, you can find it at: http://nsvisualtraceanalyzer.wordpress.com/ The blog allows to download the latest version of the application and the first version of the manual. I know the application could be much more intuitive, and the manual much more detailed, but I'm a little out of time to update it... :( I hope it will be useful to someone anyway. :) Questions and suggestions are always welcome. Best regards, Fernando Rocha Ataur wrote: It's a very good news that a trace analyzer is now open for all. I have downloaded the file and unzipped it. But don't find any help file how to use it Please help me on how I can use this trace analyzer to compare the overhead of different classes of routing protocols. I appreciate your help. -- View this message in context: http://old.nabble.com/NS2-Visual-Trace-Analyzer-tp17961607p34124405.html Sent from the ns-users mailing list archive at Nabble.com.
Re: [ns] NS2 Visual Trace Analyzer
Hi, I've checked the links and they are working well with my computer... You can download the application here: http://student.dei.uc.pt/~frocha/ns/NS2-VisualTraceAnalyzer-0.2.72.rar and the manual file here: http://nsvisualtraceanalyzer.files.wordpress.com/2012/07/ns2-visual-trace-analyzer-manual.pdf I hope they work.
