[ns] Window Scale Option
Hi everyone. I made a question before but now i'll be more specific.My question is: Window Scale Option was implemented in RFC 1072 and RFC 1323. All the news TCP implementations has implemented Window Scale Option?Is implemented too in older TCP implementations? How i must configure window scale option in ns?Is set auto when i choose a implementation with window scale option? Thanks a lot for reading this and thanks for everyone that can help me. _ Dale rienda suelta a tu tiempo libre. Mil ideas para exprimir tu ocio con MSN Entretenimiento. http://entretenimiento.msn.es/
[ns] how to trace only dropped packetes
hi , I am implementing a wired network in ns ,the generated trace file is very large in size ,I am interested only in dropped packets , can any body suggest me ,how can I get trace file containg dropped events only
Re: [ns] Animating wireless transmissions in nam
Hi,
I have attached 3 files for you to run. These files are copied from
some online resources, but I applied a couple of different stuff to the
codes. The scen and tcp files are the scenario and the connection
pattern files respectively. Just copy these 3 files into a folder, then
run first10.tcl. After running it, it will produce out10.nam and
out10.tr. When you run out10.nam with running the comand nam
out10.nam it will open a nam window. The simulation is too slow, so
just to be able to see the file transmissions, you might need to
increase the speed from the bar at the right top of the window (do not
forget to press play button!!!). Then you should see the rreq's sent
and forwarded by the nodes, and also the data packets...
Thes files work on ns-2.29 as well. I tried it.
I hope this helps.
Best regards
Cenker

Hi,
I work with AODV on ns-allinone-2.28 on cygwin. When
I run the
simulation I can see the rreq, rrep, and data packet
transmissions
among nodes.

Hi Dhammika,
i think nam does not support the visualization of
packet flows for
wireless
traces at the moment. It`s only possible to
visualize the node
movements.

Betreff: [ns] Animating wireless transmissions in

Hi,
I am trying to animate wireless transmissions in
nam. The protocol
that I am working on seems to work fine, but nam
doesn't show packet
transmissions. Can anyone advice me on how to
enable tracing/animating
packet transmissions. Your help would be greatly
appreciated.
thanks in advance

[ns] setting contention window on each node
Good evening ns-users, Is there any idea on how i can set different contention window ranges (CWmin,CWmax) on each node? Can i do that from the tcl script with a particular command? Or do i have to modify any ns2 source code? I would be grateful if you could give me any advice or hint on this subject Thanks in advance for your attention and time, Regards, Michael - Χρησιμοποιείτε Yahoo!

[ns] how to form clusters for distributed approach
Hi , My Project is Address Autoconfiguraion in MANET and i have to do that in Distributed Approach.For Distributed approach,the network area should be splitted into many subareas so that there will be several servers in one full network area.My doubt is 1. Whether the area should be seperated into many grids and in each grid we have to assign one server? or 2. No need of grid formation.the nodes can be placed anywhere.In such case how to limit the range of node.(since one node's broadcast message will be received to all in the network area.according to my pjt node sholud be reachable only from its server and not any other server.) but server-server communication sholud be there. If anyone knows,pls suggest ur ideas. Thanks in advance. Dheepa Send instant messages to your online friends http://in.messenger.yahoo.com

Hi , Can we find the position of the node in C program? I'll assign the node with its position in tcl file statically.then i have to find the position(x and y dimension) of the node in C coding.is there any command for getting the positions directly?
