This document proposes a model-based framework for analyzing wireless system architectures for real-time applications. The framework uses AADL to describe an analysis-oriented architecture model with modular components. It also develops tool chains to analyze system performance through simulation. The framework supports detailed and automated analysis of complex networked wireless systems, as demonstrated through examples from wireless healthcare and video broadcasting.

1. MODEL-BASED ANALYSIS OF WIRELESS SYSTEM ARCHITECTURES FOR
REAL-TIME APPLICATIONS
ABSTRACT:
We propose a model-based description and analysis framework for the design of wireless system
architectures. Its aim is to address the shortcomings of existing approaches to system verification
and the tracking of anomalies in safety-critical wireless systems. We use Architecture Analysis
and Description Language (AADL) to describe an analysis-oriented architecture model with
highly modular components. We also develop the cooperative tool chains required to analyze the
performance of a wireless system by simulation. We show how this framework can support a
detailed and largely automated analysis of a complicated, networked wireless system using
examples from wireless healthcare and video broadcasting.
