Wireless Sensor Node = Sensor + Actuator + ADC + Microprocessor + Powering Unit + Communication Unit (RF Transceiver)
An ad hoc network of self-powered and self-configuring sensor nodes for collectively sensing environmental data and performing data aggregation and actuation functions reliably, efficiently, and accurately .
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.
