Algorithm 2: Algorithms for notification

Data: $MESSAGE=(location,Owner\_Info,Vehicle\_Info)$  Result: Ambulance Dispatched;  Server decode the message;  lat1 = start.lat;  lon1 = start.lng;  lat2 = end.lat;  on2 = end.lng;  dLat = lat2 - lat1;  dLon = lon2 - lon1;  a= Math.sin(dLat / 2) * Math.sin(dLat / 2);  b= Math.cos(this.toRad(lat1)) * Math.cos(this.toRad(lat2));  c= Math.sin(dLon / 2) * Math.sin(dLon / 2);  d= a+b*c;  e= 2 * Math.atan2(Math.sqrt(d), Math.sqrt(1 - d));  Dist= R * c;  Cloud finds the nearest hospital using the HAVERSINE;  Hospital= nearest_hospital;  Update the data base;  Server sends notification to Hospital Web Interface;  Hospital dispatch the ambulance;
