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.

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. 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. 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. 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. 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. 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. 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.

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. Conclusion
12
Our proposal shares information by using an ad-
hoc network system for the triage.
More lives can be saved.

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.
