What do you call messages ? DTN nodes communicate by exchanging bundles. Theses can be seen as "messages" too, even though, as it is the bundle protocol, we prefer the term "bundle". You can send and receive bundle (text, binary, files, whatever) using dtnsend and dtnreceived as Stephan mentionned. You can find a short explanation of tools like dtn(send|receive) on the ibr-dtn webpage: list of toolshttp://trac.ibr.cs.tu-bs.de/project-cm-2012-ibrdtn/wiki/toollist

Hi, you can either use the (Java) Api or use dtnsend/receive as well: $ echo this is a testmessage | dtnsend dtn://foo/bar What do you mean by songs? MP3-files are files as well and can be sent like any other file ;)

Hi ,

Can someone please explain for me how users exchange messages in IBR-DTN ?

And where this is implemented in the code ?

To exchange files we use dtnsend and dtnrecv , can we for example exchange songs or other types of messages ?

I really appreciate if someone could answer me .

Thank you

Since IBR-DTN is an implementation of the Bundle Protocol (RFC5050), all data is put into bundles and then transmitted. It is a bit like a TCP packet...
