hello everybody........
am using NS2 4 my thesis and simulating a wireless n/w... i need to compare performance metrics lik ( throughput,routing load, packet delay) for dsr and aodv... and i dont have idea for calculating these.... could anyone plz, help me in sharing me the sample code for these that retriving the datas from trace files...... thank u in advance, regards, Priyanka ________________________________ ________________________________ From: "ns-users-requ...@isi.edu" <ns-users-requ...@isi.edu> To: ns-users@ISI.EDU Sent: Thursday, 30 July, 2009 5:31:16 AM Subject: Ns-users Digest, Vol 67, Issue 29 Send Ns-users mailing list submissions to ns-users@isi.edu To subscribe or unsubscribe via the World Wide Web, visit http://mailman.isi.edu/mailman/listinfo/ns-users or, via email, send a message with subject or body 'help' to ns-users-requ...@isi.edu You can reach the person managing the list at ns-users-ow...@isi.edu When replying, please edit your Subject line so it is more specific than "Re: Contents of Ns-users digest..."

Determine which Link Metric is in ur consideration. 2)Then look for the suitable routing protocol that deals with those link metric in contributed code for NS2 . 3) If it is available, move forward; else write codes and incorporate it NS2 :( --- On Tue, 7/28/09, Yota Alexiou <giotuel1...@hotmail.com> wrote: > From: Yota Alexiou <giotuel1...@hotmail.com> > Subject: [ns] Qos in routing protocol for ad hoc > To: ns-users@ISI.EDU > Date: Tuesday, July 28, 2009, 1:48 PM > > > Hello!I am doing my thesis on qos in routing for ad hoc > networks!Has anyone got the qos version for AODV routing > protocol or any other routing protocol that supports qos > implemented in ns2??I would be really grateful if anyone > could help me beacuse I m running out of > time!!Pleaaaaaase!!! > > Thank you in advance!! > > _________________________________________________________________ > Show them the way!

The Link between Node 2 and Node 3 should be scientific overloaded. Therefor there is further UDP Traffic from Node 1 to Node 5. The Audio Signals are realised with a RTP Agent and a RealAudio Application And here is my question: Why does my Priority control not work? (It's in the Funktion "attach-expoo-traffic") I guess I forgot something but I don't know what. Further my next problem? How can I change the RTP package size of my audio signals?

i assumed the base station coverage area is about 250m radius.could this be the issue?attached is the network diagram/schematic showing mobile node movement and tcl file regards dapo ------------------------------ Message: 4 Date: Tue, 28 Jul 2009 22:23:38 +0100 From: "S.M.

I am also looking for the same thing. I have found a website which has some scripts but it doesn't aloow to download. You can have a look on them. http://en.pudn.com/downloads95/sourcecode/unix_linux/network/detail381235_en.html So, if you or anyone reading this email have the scripts for calculating delay, throughput and loss in wireless ad hoc networks please help.

I've tryed the um-OLSR with UWB merz module and 802_15_4 provided with NS2 but they are not working. Since i've seen some paper on the net comparing OLSR to other ad hoc routing protocols, i'like to know if there are some public implementation working with 802_15_4 + OLSR THank you very much in advice.
