Dear all I am new to NS_2. I run the simple-wireless.tcl of Marc Greis's tutorial in ns-2.27. Everything works fine. But when I change the TCP agent to the UDP agent and change traffic model from FTP to CBR, ns-2 reports errors like following:
num_nodes is set 2 INITIALIZE THE LIST xListHead Starting Simulation... channel.cc:sendUp - Calc highestAntennaZ_ and distCST_ highestAntennaZ_ = 1.5, distCST_ = 550.0 SORTING LISTS ...DONE! ns: _o50 start: (_o50 cmd line 1) invoked from within "_o50 cmd start" invoked from within "catch "$self cmd $args" ret" invoked from within "if [catch "$self cmd $args" ret] { set cls [$self info class] global errorInfo set savedInfo $errorInfo error "error when calling class $cls: $args" $..." (procedure "_o50" line 2) (SplitObject unknown line 2) invoked from within "_o50 start" Anyone has any idea why is so? Thanks very much! Kai
