How aryankv08-png/medigrid- works

MediGrid is a prototype for coordinating ambulances, hospital beds, and inter-hospital transfers. Ambulance, hospital, and control-room clients connect over WebSocket, register, and send location, bed, or transfer messages; the server applies rate limits, finds and reserves a suitable bed, and returns or broadcasts updates. HTTP also exposes health and emergency-request data. MySQL holds operational records, Redis supports limits, locks, and cross-instance fanout, and RabbitMQ plus a worker handle reliable events and transfer workflows. The README describes these capabilities; some server and worker implementation details were not sampled.
