I am trying to identify the best appraoch for multiple view-models communication mechanism (eg: View-Model A & View Model B are loosely coupled. Now I want to pass one parameter value to my View Model B from A. I don't want to use EvenAggregator and the models are independent).

The Event Aggregator is one of the option available however i am trying to avoid that usage for normal communication because of the security (due to its Global behaviour).

I used a controller in my Application and can easily route the data between two view-models. Is the controller in MVVM & Prism 4.0 a good approach?

If not, then can some one suggest or direct me to the better approach?

The best approach is to create an intermediate layer of Services

Can you please elaborate? I didn't get the point intermediate service and how that will communicate directly to the 2nd view model
