• 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.
