Proposed Methodology
Process Flow Diagram
Gateway-centric disaster communication and escalation workflow
Disaster / telecom failure detected
Fixed HELPNET field node in assigned area
Area representative selects canned emergency
condition
Node attaches symbolic area code and battery status
Battery
low?
YES
Compact structured payload created
Use hand-crank to
recharge battery
Transmit through multi-hop long-range network
Nearest node receives alert and Transmit to
gateway node (rescue node)
Gateway node receives alert
Raspberry Pi reads payload through serial
Resolve symbolic code to readable area name
Publish expanded record to cloud / dashboard
and Rescue dashboard shows alert for
coordination
