Do the same thing for Y and Z (replace X_ with Y_ or Z_) (but actually you don't need the Z). Best regards,

You need to compile it with a C++ compiler. For example you have a file test.cc, you can compile this file with this command in Terminal: gcc test.cc -o test.o Then set the execute permission for the output file test.o (with chmod) and you can run the compiled file. For example typing this command in the Terminal (at the directory that contains the file test.o): ./test.o Best regards,

Is it the transmission power?). But in nsnam you can display a label above a node, by add this command in the TCL script: $node label "thing_you_want_to_display" You can display value of a variable, or a text string, or both as the label of a node in nsnam.

[ns] How to get the current transmission power of a mobile node?
Hi everybody, I would like to ask, in ns2 is there any way to get the current transmission power of a mobile node? I see that the transmission power is stored in a variable named Pt_ as defined in wirelessphy.h. There is also a C++ function named getPt() which is defined in the file wirelessphy.cc, it returns the value of Pt_ variable. So how can I "call" this function via a TCL script? Best regards,
