Re: [ns] TwoStateMarkov
You might want to search the ns archives for "error model" for a list of
previous discussions regarding this issue. You could also check the list of
contributed modules. There are at least two modules that I know of that
would be of help to you on the "contributed modules" page.
Good luck,
Hussein.
