A goal of the
Arogyasree project is to bring the expertise of doctors in the urban areas
closer to the patients in the rural areas. The telecommunications and Internet
The sheer number of underprivileged masses calls for the implementation of a large-scale telemedicine solution capable of managing the enormous amounts of patient data and providing medical services across the country. This gives rise to several issues such as scalability, robustness, cost-effectiveness, coverage width, context-awareness etc.
Figure 1. Life cycle of a patient request in Arogyasree
Arogyasree (figure 1) is a context-aware, P2P data grid framework for mobile telemedicine. This Internet-based scalable system integrates multiple hospitals, mobile medical specialists and rural mobile units/clinics to form a large virtual enterprise.

Arogyasree supports mobility both at the doctor's and the patient's end. Trained nurses in rural health centres can carry portable instruments for measuring vital health parameters such as blood pressure, electrocardiogram, blood sugar, weight, etc. These devices are wirelessly (Bluetooth/ZigBee) connected with a Smartphone, which transfers the data into our data Grid. Schedulers in the Grid can then find appropriate physicians to forward requests to. Willing physicians can make an evaluation of the measuring data and can provide consultations/therapeutic instructions by telephone/Internet.

is collaborative work with Prof. Wilhelm Stork's team at the University of

Step 1: Patient registers with the system
Step 2: The patient gets an id on registration.
This id will be encoded into a smart card.
Step 3: Uploading the patient request onto the data grid.
The health worker captures the ECG from the patient using the ECG jacket which is then transferred to the PDA of the health worker. The patient id, category of ailment, and location are provided as inputs.
Step 4: Request gets redirected to a capable node in the data grid for being served.
The health worker specifies the mobile no., ECG image file and other attributes of the patient and uploads the request.
Step 5: The system schedules the request.
The doctors are already registered with the system (with their area of expertise). The request is scheduled to a nearby available doctor by means of SMS/email. The doctor can then look at the patient request on the PDA and provide the response. The doctor can also view the past history of the patient.
Step 6: The doctor provides the response which is relayed to the health worker.
