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.

“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.
