Published on


Robert Scholz presented the importance to investigate concepts, which enable the unification and the common understanding and the replication of ICT architectures. He pointed out how to achieve an unified approach which aims to fulfill complex and integrative ICT solutions for Smart Cities. The presented approach aims to base on the idea of openness with 1) respect to interfaces 2)software components and 3) data. It was shown that those are seen as the main ingredient of an ICT eco-system for Smart Cities.

#CeDEM17 - Towards an Open Data based ICT Reference Architecture for Smart Cities

  1. 1. Towards an Open Data based ICT Reference Architecture for Smart Cities Nikolay Tcholtchev, Philipp Lämmel, Robert Scholz, Evanela Lapi and Ina Schieferdecker
  2. 2. 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
  3. 3. • 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 3 Todays Agenda
  4. 4. 4 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
  5. 5. • 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 5 Goals of an ICT Reference Architecture (2/2)
  6. 6. 6 Views on ICT Reference Architecture
  7. 7. • Type of ‚information‘ transmitted • Relevant Standards • Common Protocols, APIs and Data formats, along with their characteristics / advantages • Security aspects? Schematic service definition 7 ‚Services‘ between layers of the ICT RA SAP ‚Service‘ Name Position on the Reference Architecture
  8. 8. • 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 … Exemplary service definition 8 ‚Services‘ between layers of the ICT RA Data Source Data - SAP Between Communication & Data Analysis/Processing DSD
  9. 9. • 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 9 Todays Agenda
  10. 10. EV Charging Infrastructure Update 10 Mapping of the modules onto the layers of the ICT Reference Architecture T3 Surveillance system (central management system)? T1 Combined Chargers (AC + DC) T2 AC Charging (Points) Charging Point Station Electric Vehicle (e.g. Car) Has (multiple) RFID? (communication standard is put forth for DC in IEC 61851- 24) (Open Carge Point Protocol (OCPP)) Open Smart Charging Protocol 1.0 (for 24h- prediction integration) Smart Grid Central Management System Data Analysis & Processing CommunicationData Sources
  11. 11. Innovative Video 11 Mapping of the modules onto the layers of the ICT Reference Architecture T2 (existing): Fibre to the Home Infrastructure (FTTH) T1: New state of the art video services HD Cameras Home Smart Appliance (Smart Router Linux PC) Mobile Phone Remote Application Home Internet Gateaway Fibre Cables 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
  12. 12. 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
  13. 13. • 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) 14 Next steps
