[ns] -k option in nam
Can anyone tell me what the -k: initial socket port number option in nam 1.11 is for? I cannot find any documentation about this option. Can nam read trace commands via sockets? This would be very convenient as the feature to read trace commands for real-time applications via streams, like cat wireless.nam | nam -, does not work with me for the precompiled binaries for Windows, neither under native Windows XP nor under Cygwin 1.5.25!

Re: [ns] ns-2 simulation
Hi Suthapuch,
Yes , if DYMO is installed with ns-2, you can use my software with it.
However, you should make some changes regarding packet size at routing
level. First you should find the size of the packet in trace file. For
example, I found that when I set packet size in tcl file to 1024 bytes,
rpktsize will be 1084 bytes at routing level in case of OLSR and AODV, and
1064 for DSR. So you need to change spktsize and rpktsize in gen_pl.tcl
file to consider DYMO. Namely you should modify the following lines which
are found in three locations in the file gen_pl.tcl:
set spktsize 1064
if {$routing == AODV || $routing == OLSR} {
set rpktsize 1084
} else {
set rpktsize 1064
}
Hope this helps.

Dear Mr. Samer Bali
I am from Thailand. I am studying master degree at KMUTT. I have
been interested in ad hoc network and DYMO routing protocol. I would measure
routing overhead and packet delivery ratio for my project. I would like to
ask you that your modules can be used with DYMO and if it is available,
could you explain how to used it. I will appreciate much for your kindness.
Finally, I apologize you at taking your time and your effort on my poor
english skill. And thank you much.
Best Regards
Suthapuch Purnaveja

[ns] Reliability and SCTP aware application
Hi, I am working with SCTP aware application. I think there is some bug in there because if I send the packets with reliability level set to 0; then it also gets retransmitted whereas it should not be retransmitted. Has anyone faced the same problem or does anyone has any suggestion? I highly appreciated any suugestions. Regards, Ashfiqua
