[ns] How to set UDP packet header parameters?
Hi all Can anybody tell me how can I set a UDP packet header parameters in TCL like Flags? Can I assign a Label to a packet? how? How can I decide what to put inside a packet's body?

[ns] tcp packet
hi all,
Does tcp packet in wireless have data in payload as whenever i tried to
print it using
if((PacketData*)p-userdata()!
=NULL) {
PacketData* packdata = (PacketData*)p-userdata();
unsigned char* pdata = (unsigned char*)packdata-data();
printf(data = %s and p data = %d ,pdata, pdata);
}
it shows some awkward result(unreadable format) with %s and blank with %c
but have some random numbers with %d, while datalen() returns 10 but
strlen(pdata) returns 1 . Can i think number returned by %d is real
payload? if no please let me know how to write payload on trace files.
Thanks

[ns] How to switch to a new frequency
Dear all, I 'm simulating a wireless network with AODV. Is it possible to instruct some of the nodes during simulation time to use a different frequency? When some nodes receive a command, I need them to change the frequency they are using and switch to a new frequency. Can you give me some guidelines how I can achieve it in c++? Thank you in advance, Lup.
[ns] Link state routing (OSPF)NS2
Hi, I was wondering if anyone has implemented OSPF in NS2? I am working on modifying the OSPF protocol. Has anyone worked on this? Aany help or advice will be truly appreciated. Regards, Shak _ http://clk.atdmt.com/UKM/go/19780/direct/01/ Do you have a story that started on Hotmail? Tell us now
[ns] Help MAODV script
Hi ! I have read the document which I attached. However, I still don't know clearly the meaning of these lines below : (puts Loading connection pattern ... ) source ../$traffic/$traffic-$senders-$receivers-2-256.aodv.$nodes (If I chance this path like : source /home/mylaptop/traffic/cbr1, is it ok? ) (puts Loading scenarios file... ) source ../scen-1500x300/scen-1500x300-$nodes-$pausetime-$mobility-$scenario (If I change this path like : ource /home/mylaptop/traffic/cenario1, is it ok ?) If anyone have implemented MAODV successfully, please explain clearly about these lines. Thanks Vo
Re: [ns] Intermediate between ns2 and web server
Hi All, I'm trying to develop a web application involving ns2. The idea is, user can write a small simulation program and submit from the front end. This program would go the web server, which will then have the script executed by ns2 (running on the server machine), and send back the output (or error message) to the user. Is there any existing software that could help me to achieve this i.e. converting a HTTP request to input for ns2 and output from ns2 to HTTP response?

[ns] wired_cum_wrireless mesh example!!
Hi, I am a grad research student of Dept of Electronic engineering of King's college London.. I intend to create a wired_cum_wireless mesh example (any ad-hoc routing is fine)..I have read in a few places in the net that the ns2 support for wired_cum_wireless mesh is poor.. Does anyone know of any known bugs??? Does anyone have a basic wired_cum_wireless mesh script that they can share??? Also when i try to run the nam file generated in wireless2.tcl the alignment of the wired and wireless nodes are a bit strange..the wired nodes (0, 1, 2) are right at the bottom..And the wireless nodes are far end at the top..(3, 4, 5) Something like below... 3 4 5 0 | 1 / / 2 I know i can change their alignment by specifying the topogies..but the way they are specified, is that a normal thing to do??/ Any help , advise in this direction will help me a lot and is highly appreciated... thanks and Regards, Svetla King's college London

[ns] Help needed in simulating Q-Routing
Hi, I have to simulate Q-routing to see the performance of the network in low and high load condition as mentioned in Justin boyne's paper. Can anyone please help me to simulate this as NS2 is new to me. I have already read many documents on Q-routing and NS manual, but i am still not able to code Q-routing. Please help me in simulation.
