Perspectives on Internet-of-Things
National Intelligence Council - “Disruptive civil
technologies: six technologies with potential
impacts on US interests out to 2025”
Likely rapid adoption and ubiquity in a number of
civil environments (e.g., water)
Cisco Internet Business Solutions Group predicts
there will be 25 billion devices connected to the
Internet by 2015 and 50 billion by 2020.
“Internet-based M2M + M2H services” services”
The Big Picture - Distributed
Real Time Monitoring and Control
Can passive approaches achieve optimal
solutions given the realities of the built
environment?
What roles can and should information
technology play in addressing specific
urban water engineering problems?
What can be done now with dynamic
intelligent controls?
What is the state of the art?
Initial Research Problem
Find the least expensive
most flexible means for
monitoring and controlling
the physical environment
and integrating internet
based datastreams.

Highly Distributed Real-Time Monitoring and Control (DTRC)
“Ecosystems” of smart environmental infrastructure
Platforms that interact and scale
Disparate data sources can be combined for visualization, analysis, and system control
– Access field and web-based data
– Interface with other systems
– Complex algorithms
– Specified data can be made available to the public
– Data access and user experience is user/group specific

Closing Thoughts – Policy and Practice
Merging of information technology and infrastructure will
increasingly be important if not critical.
Low cost, reliable, and highly functional sensors and
sensor platforms will change everything we know about
how we currently regulate, enforce, and understand
environmental systems.
Be creative, explore the possibilities, the future is
blindingly interesting.
