ICT infrastructure for a resilient society
March 17, 2015
Toshitaka Tsuda
Waseda University
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
Telephone number Web server name Contents 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
- Ad-hoc network
- Cognitive radio
etc.
2. Power issue - Low power consumption hardware
- SON(Self organizing network)
- Energy harvesting
