You are asking whether it is possible to code your agent to use the
route model APIs?  Certainly, yes.

However, the route model APIs only perform topology change
operations.  They are not a general form the `at' methods.
Look at the examples in the ~ns/tcl/ex directory for
suggestions on how to perofrm deferred executions in general.

I'd also very strongly recommend that you take a look at the ns 
ocumentation (http://www-mash.cs.berkeley.edu/ns/nsDoc.ps.gz);
although it is not up to date, it still has a lot of information
that might find useful.
