Tsunami warning, landslide warning, debris flow monitoring systems
Earthquake Detection
 Affordable detectors based on that
 P (primary/pressure) wave travels
faster than S (secondary/shear)
waves, and generate only shock
 Slower S waves are destructive
 Early earthquake warning systems
consisting of seismic motion sensors
networked with computer(s)
 Issue warning based on likely
strength and progression of
seismic events and
 Can allow warning 20 seconds or
more before ground motion.

Common Alert Protocol
ITU-T Recommendation X 1303 (07/2007)
A common format that supports
 Broadcast of messages of all
types to all public alert systems
 Message exchange between
emergency information systems
 Aggregation and correlation of
warnings from multiple sources
 End-to-end authentication and
validation
 Automatic reports by sensor
systems to analysis centers
 Automatic processing by smart
devices and applications

 Dependable, low-cost,
customizable smart devices for
enhanced disaster readiness

enhanced disaster prepared smart
environment,” by Liu, Chu and
Shih, in IEEE Computer
“Ubiquitous smart devices and
applications for disaster
preparedness,” by Liao, et al, in
Proceedings of UFirst, UIC 2012
Challenges
 Minimizing energy consumption for iGaDs on
battery powered platforms
 Pushing alert messages to iGaDs and people
 Interfaces and standards, including
 With information sources (e.g., BIM, store
layouts, building management information
system, etc.)
 With sensors, actuators, location devices
and services, etc.
 Creating dual (everyday and emergency) use
applications

Observations
 On BIM data:
Data on building information modeling, store layouts, etc.
are likely to become BIG with increasingly wider adoption
of the BIM process worldwide
 3 – 6D BIM data are highly structured and complex
 Privacy protection is important
 Current obstacles include missing international
standards and interoperability and exchangeable of
information in digital formats
On use of BIM data by iGaDs
 Small grains of data are accessed by millions of smart
devices and applications concurrently
 Real-time response is always required; sometimes with
end-to-end delay < 1 sec.


IGaDs + Cloud + Big data
= Massive Business
Opportunity
