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.

Proposal Of An Ad Hoc Network System Sharing Triage Information

  1. 1. Proposal of an ad-hoc network system sharing triage Information at a disaster scene Ryukoku University Hideomi MIYAMATSU Wataru UEMURA Masashi MURATA
  2. 2. Background 2 The triage is used injured people in the disaster scene It is difficult to share injured peoples’ information The network sharing information can be constructed by an ad-hoc network technology
  3. 3. What is triage? 3 To rescue a lot of lives in the disaster scene where talent and materials are insufficient, priority is applied to treatment. ( Information is shared with the tag of paper) Because paper is used, it is difficult to share information.
  4. 4. What is an ad-hoc network? 4 Network is constructed of nodes Does not need the base station We can add and remove node. As the result, node can move anywhere.
  5. 5. Problem 5 The doctor puts up tag to the injured people The rescue team transports the injured people It is necessary to cooperate with the doctor between rescue teams
  6. 6. Problem 6 It is necessary to cooperate with the doctor between rescue teams Because the triage tag by using a paper, it is difficult to take cooperation. Information does not be shared. We solve a problem by sending an information on the network
  7. 7. By using an ad-hoc network 7 The communication between nodes can be done even if there is no AP. Each node equipped with wireless LAN can be used. A special node is unnecessary.
  8. 8. Proposal 8 Injured peoples’ triage information is shared, injured peoples' transportation efficiency is improved. 1 The doctor does the triage. The doctor and 3 2 The doctor delivers triage rescue personnel 2 have the node information by using an ad-hoc network 4 1 3 The rescue team receives information 2 The patient is attested 3 4 The rescue team replies to the doctor, by the tag number. "Transport injured people" Injured peoples’ position is confirmed by using GPS The doctor confirms that transportation is done by the reply.
  9. 9. Data’s flooding (transmist) 9 1 2 Doctor’s node Rescue’s node or Rescue’s node Routing table Doctor’s node Sequence Server ID number Forward 1 1 Doctor’s Sequence Doctor’s ID number ID rescue’s node Sequence Server ID number Forward Data’s flooding 2 Doctor’s Sequence Doctor’s ID or ID number Broadcast Rescue’sID
  10. 10. Data’s reply (receive) 10 1 2 Doctor’s node Rescue’s node or Rescue’s node Routing table Doctor’s node Sequence Server ID Forward 1 1 number Doctor’s Sequence Doctor’s ID number ID rescue’s node Sequence Server ID number Forward Data’s reply 2 Doctor’s Sequence Doctor’s ID Unicast ID number or Rescue’sID
  11. 11. Advantage 11 Time to look for the injured people decreases Transportation time becomes short It is easy to understand the situation of the disaster scene We can make the plan quickly
  12. 12. Conclusion 12 Our proposal shares information by using an ad- hoc network system for the triage. More lives can be saved.
  13. 13. For the future work 13 The program cannot be mounted yet. I want to build the program into the NetWalker, and an iPhone for the next step.
