Towards an Open Data based ICT Reference

Architecture for Smart Cities

Nikolay Tcholtchev, Philipp Lämmel, Robert Scholz, Evanela Lapi and

Ina Schieferdecker

The Triangulum Project

One of nine Horizon 2020 Smart City Lighthouse

Projects, including 22 European partners.

Lighthouse Cities: Stavanger, Manchester, Eindhoven

Follower Cities: Leipzig, Prague, Sabadell

Goals:

• Intelligent energy management and reduction of

energy consumption

• Adaptive and dynamic ICT data hub(s)

• Increase usage of renewable energy and EV

• Activation of citizens as co-creators

• Replication of Solutions (ICT Reference

Architecture)

• Design and implementation of innovative Business

Models

• Smart City Governance Model & Decision tool

• Introduction to the Triangulum Project

• Goals of an ICT Reference Architecture

• The current model for the ICT Reference Architecture

and ‚services‘ between layers

• Mapping of Solutions onto the ICT RA

• Relevance for eGovernment / eDemocracy

• Standardization

• Next steps

Goals of an ICT Reference Architecture (1/2)

The main goals of such an ICT Reference Architecture are as follows:

• Provide an unified view and understanding on the ICT strategies of the involved cities, that

also accommodates legacy solutions

• Enable reuse of the Triangulum components and/or solutions by cities participating in the

project but also by cities outside the consortium

• Contributing to Smart City standardization at e.g. ISO or ETSI by proposing parts to the

standardization bodies

• Identify interfaces for communication between the involved components

• Enable the exchange and interoperability of various components and/or software

packages along the identified and standardized interfaces, similiar to the ISO TCP/IP OSI

model

• Define the ICT Reference Architecture and interfaces in a way that Open Source

components can be used, in order to enable cities and communities to get independent

from particular vendors and highlight the importance of open data

Views on ICT Reference Architecture

• Type of ‚information‘ transmitted

• Relevant Standards

• Common Protocols, APIs and Data formats, along with their

characteristics / advantages

• Security aspects?

‚Services‘ between layers of the ICT RA

SAP‚Service‘ Name

Position on the Reference Architecture

• Usually (raw) sensor data in real-time (e.g. regarding energy

usage) is provided through this SAP

• Relevant Standards: RFC 4944-6Lowpan, …

• Protocols: Threat || Zigbee || MQTT || CoAP /UDP/IPv6 + low

energy bluetooth, Formats: Binary, Advantages: Interoperability

• Alternative: Zwave AppL / ZwaveTL/ ZwaveNL/

Zwave Radio …

low energy Bluetooth for control; direct video signal

Session Initiation Protocol | SDP/TCP + TLS | UDP/ (IP/ Ethernet) for connection negotiation

H.246/RTP/TLS(SRTP)/IP for video/streaming data

Data Analysis & Processing

CommunicationData Sources

Direct Application of RA in possible follower city projects such as:

• A digital tool for optimization of space usage in public buildings

• Video-Conference System for Urban- (as well as Health-) Services (similiar to the

solution shown before)

• ICT tools for Citizen Participation

Indirect incentives:

• Provision of incentives to citizen for energy reduction

• Attraction of Businesses/Investments through tools from the ICT Hub (such as a

solar GIS-map) and creation of solutions with citizen benefit through the provision

of freely useable (=open) data.

12

Relevance for eGovernance / eDemocracy

• Continued refinement/definition of SAPs

• Integration of more security aspects into ICT Reference

Architecture

• Application of the RA in the Follower Cities

• Continued contribution to standardization activities (DIN SPEC

91347 OUP & EIP SCC MoU)
