Hello to everyone, I'm a complete noob at NS but I've checked some tutorials, run a couple of tcl examples but I still can't combine all these so as to do what I want. That is to create an RTP session between 2 nodes. The connection between them has to be wireless. I'm trying to do the same things as shown in 2 examples of /ns-2.34/tcl/ex, simple-wireless.tcl and simple-rtp.tcl. I get this weird error but I haven't found anything on the web:
num_nodes is set 2 warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl INITIALIZE THE LIST xListHead Starting Simulation... channel.cc:sendUp - Calc highestAntennaZ_ and distCST_ highestAntennaZ_ = 1.5, distCST_ = 550.0 SORTING LISTS ...DONE! ns: _o19 new-group 0 -2147483648 -1 cache-miss: can't read "protocols_(-1)": no such variable while executing "$protocols_($iface) upcall $code $source $group $iface" (procedure "_o20" line 9) (mrtObject upcall line 9) invoked from within "$mrtObject_ upcall $code $src $group $iface" (procedure "_o14" line 3) (Node new-group line 3) invoked from within "$node_ new-group $src $group $iface $code" (procedure "_o19" line 3) (Classifier/Multicast new-group line 3) invoked from within "_o19 new-group 0 -2147483648 -1 cache-miss" I think it has to do with the function mrtObject instproc upcall in the file /ns-2.34/tcl/mcast/McastProto.tcl but I'd like to know what I've got to do about it. I saw that RTP stuff is still undocumented (http://www.isi.edu/nsnam/ns/doc/ns_doc.pdf). I would really appreciate any help/hint/suggestion. Thank you :-) http://old.nabble.com/file/p31407109/rtpwi.tcl rtpwi.tcl -- View this message in context: http://old.nabble.com/RTP-over-wireless-connection-between-two-nodes-tp31407109p31407109.html Sent from the ns-users mailing list archive at Nabble.com.
