Hi:
As we know, before creating nodes in tcl script, we need to configure them
with various options like -macType -ifqType -phyType -channel and so on. I
just want to know that after creating these nodes in tcl script, I want to
change some nodes frequency in C++ dynamically, I tried the following code
but failed:
Tcl& tcl = Tcl::instance();
tcl.evalf("$opt(netif) set freq_ newFreq);
if(tcl.result() != TCL_OK)
cout << "set new freq failure." << endl;
So please help me what else should I do to make the change take effect.
Call node-config again or what else ?
Any suggestions will be appreciated, Thanks.
