Requirements to ICT in disaster1.

Quick recognition of situation and info. sharing

2.

Estimation of the situation to come3.

Effcient/effective planning of countermeasures

4.

Provisioning to people with necessary andtrustable information in the form of easily
understood

0. Reliable ICT infrastructure to support above
mentioned process2Some key features of ICT infrastructure
 To have a variety of method to proved a function
 To have a total view including a town design

 System/device would be used in a normal situation
 Flexibility of a system+ user’s viewpoints
 Automatic collection of context information

 Human friendly HCI usable by non experienced
 Improve the trust of information

Would be used in a normal situation
 There are some barriers to implement disaster dedicatedsystems
 How much investment will be rationalized to a system

dedicated to situations seldom happen?
 ICT environment is daily evolving. Disaster dedicated system

may not be connected to other system because it may beobsolete when in use.
 Things that are not used daily are difficult to use for non

expert users.

7Flexibility
 Mechanism to dynamically assign resources depending on

the situation is necessary.
 There are several approaches going on to answer thisrequirement.
 Cloud computing and virtual machine(VM) SDR/SDR(Software Defined Radio/Network)
 NFV(Network Function Virtualization)
 Big data processing ICN(Information Centric Networking) Proactive use of these new technologies isessential.

Contents(Information) Centric Network Change of addressing scheme

Telephone number

Web server nameContents name

 Change of routing scheme

Make link based on server name(IP address)
CCN router find the contents location based on the contents name,and retrieve the contents.

(Several aspects that will contribute to disaster situation)
 Dynamic network caching Multi-path routing
 Mobility tolerant

Approaches to disaster resilient network
1. More flexibility- Software programmable node
- Dynamic optical path setting Capacity- Ad-hoc network～10kbit/s- Cognitive radioetc.

Future:Dynamic allocation

Current:
Fixed allocation

Call suppression～10bit/s

Number of users
Normal situation

2. Power issue- Low power consumption hardware- SON(Self organizing network)- Energy harvesting
