Imagine designing a system, choosing and defining a specific architecture, and implementing a design only to find out that the system is not fully compatible with the chosen architecture, or another architecture would have met your constraints more efficiently. Not only have you wasted time and money but also your overall performance is sub-optimal. Being able to accurately estimate how well a system will perform on a specific architecture before completing the system allows a designer to decide if that architecture is feasible to implement. It also allows for trade-off decisions concerning cost, design time, and performance to be made at a pre-implementation stage. The steps described in this paper to model the Pico-Radio application layer allow designers to make trade-off and optimization decisions at a high level of abstraction.
