[ns] Problem in start ontime ftp application in DSDV protocol
Hi
Please run the script file(this is Wireless senario).
Could you tel me, why the data packet's send start at (about) 50th Second?
I have set it to start at 10th second.($ns at 10 $ftp start).
I have used DSDV routing protocol, and I think the routing table in
all 3 nodes are created until 3 second(Right?). So, why the packet
sending late until 50th second?
The Script File is as:

[ns] always AODV specify shortest path?
Hi Does the AODV routing protocol guaranty always specify shortest path to destination? Suppose that, there are multiple paths to a destination, and the shortest path has heavy traffic, so in this shortest path the RREQ packet will receive to destination latter that long but low traffic path. Is it correct? Any Idea about this case?! -- Regards; Hosseini Nazhad.
[ns] problem in modifying dsragent.cc file
Problem : Hi i am a newbie to ns2 using fedora 14 using ns2.31 I know that this problem is explained in the ns2 faq section but I am unable to do it , so it would be gr8 if you can be helpful to me in this case. Whenever I am modifying dsragent.cc file I am unable to see any changes in the tracefiles. I am changing the options in the file then using these commands inns-2 directory make clean make depend make to recompile. Also the ns files are getting executed even after I am deleting the object files manually .How is that even possible?? ps note that i am deleting the .o files from the place where the LD_LIBRARY_PATH points to. I used env from bash to see the place. First i was doing this from root and thought maybe that was causing problem but the same problem is coming when i am doing it from a normal user. Can u please give me pointers to what can the possible cause of this Regards Shaunak Bhatt

Hi, While installing NS2, may your nam had errors that is your nam has failed while compilation. Try to compile nam separately and clear those errors. Then nam will work. All the best!!! -- Regards, Subha
Re: [ns] problem with NIST Mob package in NS-2.29 (zmezm 14)
Hi, To clear extra qualification error, you just need to remove that class. In your case, go to 620 line of mac802.11.h. then remove *Mac802.11:: keep calFreq as it is.* -- Regards, Subha
Re: [ns] Changing behaviour of node.
Has anybody worked on network coding in ns2?... I hav made changes in my ns2 2.27 and put network coding in it.. but it is giving an rrror called segmentation fault when i run the examples with network coding... Can anyone tell me the reason behind this?? Thanx.. swat_nag wrote: Yes, i want to do network coding... Can you tell me how to do it?as in what all do i have to know to go about it?... Manoj_Kumar wrote: swat_nag wrote: Im kind of new to ns2, i need help in changing the default working of the node. I dont know how to apply the changes to the code. COnsider 3 nodes: A,B and C. C is like a router. A sends packet to B through C and B sends to A via C. In normal operation, when C gets the packets simultaneously, it sends one by one to A and after that to B (not at a time). But i want C to send both the packets simultaneously to A and B. Like this in the receiver end, A will XOR the received packets with its own packet so that it receives its required packet. B also does the same. Can u please tell me how to implement this?...and wat changes are to be made and where?... I would really appreciate your help!
