Model-based architecture analysis for wireless healthcare

The primary challenges in deploying a wireless healthcare solution stem from real-time, distributed resource constraints, as well as stringent clinical requirements of reliability, safety, device interoperability, QoS guarantee, and privacy/security. Although optimized solutions exist for each individual element of the system, the complex, distributed, and concurrent interactions among multiple subsystems make system integration a costly bottleneck. We show that end-to-end modeling and analysis using the formalisms of architecture description languages like AADL can alleviate the hurdles of system integration and provide an effective way of addressing these challenges, thereby, making deployments possible.
