1. Pervasive Health Monitoring Krishna Venkatasubramanian IMPACT LAB Arizona State University

2. Ayushman*: A Pervasive Healthcare System Project @ IMPACT Lab, Arizona State University To provide a dependable, non-intrusive, secure, real- time automated health monitoring. Should be scalable and flexible enough to be used in diverse scenarios from home based monitoring to disaster relief, with minimal customization. Vision * Sanskrit for long life To provide a realistic environment (test-bed) for testing communication protocols and systems for medical applications.

3. Medical Data Management Architecture

4. Ayushman: Physical Organization Environmental Sensors (Temperature etc) Medical Sensors (EKG, BP) controlled By Mica2 motes Body Based Intelligence Home/Ward Based Intelligence External Gateway Central Server Medical Facility Based Intelligence Medical Professional Internet Local Gateway

5. Ayushman: Remote Medical Monitoring Testbed consists of medical devices interfaced using crowssbow motes to a PDA. Medical devices integrated include: BP monitor (Suntech), EKG monitor (Vernier) and Gait Monitor (Mica2 based sensors). Supports query based and continuous data collection. Implements caching & aggregation. System Constrainst : Low reliability Lack of bandwidth Low memory for processing. BP and EKG Monitoring Gait Monitoring

6. Current Work Develop a effective visualization tools for medical data Integrate multi-interface based star-gate for local gateway Develop performance management infrastructure  Monitoring, Visualizing sensor performance  Controlling sensors to tune performance according to our needs.
