Smart City Architectures
• Smart City technologies are being
developed and deployed at a rapid pace.
• Many previous smart city deployments are
custom solutions.
• A number of architectural design efforts
are underway worldwide but have not yet
converged.
• NIST and its partners are convening a
public working group to distill a common
set of architectural features from these
architectural efforts and city stakeholders.

Goal: A reference framework for the development of
architectures for incremental and composable Smart
Cities

How We Envision It
This new activity builds on two NIST initiatives:
o The Global Cities Teams Challenge that encourages “action clusters”
to form and collaborate to demonstrate technologies at city scale.
o The CPS Public Working Group that is developing a Framework for
Cyber-Physical Systems (CPS) which provides for a scientific
underpinning of the description of the CPS/Internet of Things.
The following already exists:
o Multiple architectures in Smart Cities, Internet of Things, and vertical
cyber-physical domains
o Example deployments from the Global Cities Teams Challenge and
others
These initiatives provide outputs that will be useful in distilling the
common requirements and solutions observed into a Smart City
Framework that supports a composable or building block
approach to Smart Cities.

Process:
1) Transform architectures to CPS

2) Transform deployments to CPS

3) Compare results of 1) and 2)
4) Broaden consensus of
intersections
5) Document Smart Cities Framework

Pivotal Points of Interoperability - PPI
To determine PPI the participants will review the following:
• Examples of current architectures
• Success stories about how seamless integrations were achieved
• Standards to support the modular integration of new functions
• Best practices - how to integrate features into existing infrastructures
• Educational materials and tools for Smart City features

If you standardize everything, you freeze out innovation. If you
standardize nothing, you get non-interoperable clusters that can’t
be easily integrated. The principle of Pivotal Points of
Interoperability is to find consensus standardized interfaces that
deal with composition of CPS without constraining innovation.

When?
The timeline:
NIST is convening a public working group from around the globe including:
• Smart city leaders, administrators and planners
• Manufacturers of Internet of Things and other Smart City related components
• Researchers studying the integration of technologies into smart city designs
• Standards organizations investigating and developing smart city standards
• Industrial and commercial consortia developing IoT specifications and
designs
• Governments involved in smart city planning and policy
Activities will begin in November 2015 with a key kickoff workshop in
February 2016 (Europe) and March 2016 (at NIST). A draft result is
planned to be available late fall, 2016
