[ns] OSPF on ns-2
Hi all, how can I configure OSPF on ns-2? I've tested the link state based protocol ( LS ), but it seems to use only the number of hops to calculate the link cost. How can I change this to consider the bandwidth? Can I set my own cost function? How? Thanks in advance, -- Pedro Dias de Oliveira Carvalho

Re: [ns] RTP over wireless connection between two nodes
ah yes i dealt with those as well. the solution is quite trivial if you know the following or if you can use google to resolve such compiler errors which i strongly suggest. A quick search reveals: When you compile, you need to make sure that the libraries are where they're supposed to be AND the header files (INCLUDE=...) are where they're supposed to be. Either one can mess you up. (The library is NOT the same as the header (.h) file. C libraries are collections of compiled objects which are LINKED to your object code by the linker. Header files are lexically included by the preprocessor) What this means is that you should make sure that aodv.h is in the AODV folder that aodv.cc is (which is indeed in the package you have I remember correctly). You should also make sure that in Makefile.in where is says INCLUDES= , that there is a line saying: -I./aodv \ (which there isn't, so if you add it , it will work) . cheers pebbles wrote: Thanx a lot for the zip file and your help!

Re: [ns] RTP over wireless connection between two nodes
well it shouldn't be related with the maodv as it is working as it should for me . Maybe solving the warning is all that is needed warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl if you post your tcl script you might get some assistance ;) pebbles wrote: Thanx for your quick reply, now I'm searching about the error it gave when I ran my tcl script. -- View this message in context: http://old.nabble.com/RTP-over-wireless-connection-between-two-nodes-tp31407109p31701718.html Sent from the ns-users mailing list archive at Nabble.com.

It's ok now! I just had to change the ns-mcast.tcl as I did in my second
post.
I'm using the example simple-wireless.tcl of ns with the option multicast
on and the error I'm getting is:

Re: [ns] RTP over wireless connection between two nodes
you can't use maodv like that !!
look in maodv-scripts folder.. and check the ns.tcl file to see how you can
configure ns to use it.

You're right!
So, if I want to use FTP or RTP I should create traffic scenarios like in
these cbr files ?
