Requirements to ICT in disaster

1. Quick recognition of situation and info. sharing

2. Estimation of the situation to come

3. Effcient/effective planning of countermeasures

4. Provisioning to people with necessary and

trustable information in the form of easily

understood

0. Reliable ICT infrastructure to support above

mentioned process 2

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 3

Would be used in a normal situation

There are some barriers to implement disaster dedicated

systems

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 be

obsolete when in use.

Things that are not used daily are difficult to use for non

expert users.

Flexibility

Mechanism to dynamically assign resources depending on the situation is necessary.

There are several approaches going on to answer this requirement.

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 is essential.

Change of addressing scheme

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

- Ad-hoc network

- Cognitive radio

etc.

2. Power issue - Low power consumption hardware

- SON(Self organizing network)

- Energy harvesting
