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.

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
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.
