In recent years, the medical doctors must distinguish condition of many injured people at a disaster quickly. Injured people are distinguished by colored paper tags by doctors, this is called triage. The triage is identification done to save more lives in the disaster scene. In this research, we propose an ad-hoc network system that enables sharing injured people’s condition and other information between rescuers and the doctors. The doctor inputs the injured people’ triage level and location information acquired from GPS their mobile node. The node manages the injured people information and network. The node sent this information to surrounding nodes through an ad-hoc network. Surrounding node retransmits its information widely. After the rescuers move the injured people, they send the completed information to the doctor's node. Thus our proposed system shares injured peoples’ information between rescuers and the doctor in an ad-hoc network.
