16.1.7 Revised format for wireless traces

In an effort to merge wireless trace, using cmu-trace objects, with ns tracing, a new, inproved trace format has been introduced. This revised trace support is backwards compatible with the old trace formatting and can be enabled by the following command:

$ns use-newtrace

This command should be called before the universal trace command $ns trace-all trace-fd. Primitive use-newtrace sets up new format for wireless tracing by setting a simulator variable called newTraceFormat. Currently this new trace support is available for wireless simulations only and shall be extended to rest of ns in the near future.

An example of the new trace format is shown below:
