Hey Matthias, Further to previous emails, I've also tried forcing
Simulator set WirelessNewTrace_ 1 in ns-default.tcl It's definitely being set (debug line), but the output log is still in old format. So, I suppose the problem must be somewhere in the nsclick stuff? It's either resetting the flag, or just not honouring it somewhere.... Again, any thoughts would be very much appreciated, Best Regards, Dave -----Original Message----- From: Matthias Kuhnert [mailto:[EMAIL PROTECTED] Sent: 26 February 2007 13:27 To: David Bath Subject: Re: [ns] new wireless trace format OK, the calling for this function for the "common" mobile node runs through the ns-lib.tcl and ns-mobilenode.tcl. First with the use-newtrace the variable WirelessNewTrace_ is set to 1, and within the creation of the mobile node the newtrace is set to the value of the WirelessNewTrace_. One thing that relates to that is, that before anything of the mobilenode is set or the node is created the call to $ns_ use-newtrace must be done... otherwise the default value of 0 is taken... You should have a look at the tcl part of the creation of the click node and perhaps compare it to the mobilenode.
