Big data & Smart Cities focusing on mobile services and human mobility patterns. John Krogstie Professor in Information Systems IDI, IME, NTNU Leader of Wireless Trondheim Living Lab 1
Smart cities involve more than smart energy use, including infrastructure for personal transport, and communication. A central point is the exploitation of pervasive sensor-networks to support: Transport and Logistics Communication Information/learning/entertainment (Edutainment) Tourism Public management and services Crime Fighting, Digital Forensics Smart Buildings Monitoring climate effects 2 -> Generic ICT challenges: Energy-efficiency, wireless technology, Modeling of organized tasks, collaboration technology, big data, complexity, dependability
Big Data research at NTNU Spearheaded by IME Lighthouse on Big Data http://www.ntnu.edu/ime/bigdata (Mostly IDI and IMF) EU Projects: PRESIOUS (FP7) and AMIDST (FP7) iad: Information Access Disruptions, a Norwegian Research Council finanized centre for research-based innovations (SFI) SIRIUS: Center for Scalable Data Access in the Oil & Gas Domain (SIRIUS) (New SFI) Several doctoral projects 3
Big Data relates to Volume refers to the large amounts of data generated Velocity refers to the speed at which new data is generated and distributed. Variety refers to the different types of data (from different data sources) that one might want to look at in concert. Veracity refers to the messiness or trustworthiness of the data. (Data quality aspect) Value. Having access to big data is no good unless one can turn it into some value. Appropriate visualization to be able to make sense of all the data 4
5 Wireless Trondheim Living Lab (WTLL) as basis for Smart City ICT Research
Living labs focus on open and user driven innovation (OUDI) A Living Lab is about experimentation and co-creation with real users in real life environments, where users together with researchers, firms and public institutions look together for new solutions, new products, new services or new business models NTNU through Wireless Trondheim Living Lab (WTLL) where a funding member of ENoLL AISBL (core 25 ENoLL members) WTLL is a cooperation between NTNU and Wireless Trondheim LtD Combine innovation activities with Design Science Research: Make and evaluate relevant artifacts 6
What is special in Wireless Trondheim? Duality between R&D and commercial utilization a stable network running commercial services and a platform for R&D on new products and services (including smart antennas, amplifiers, radios). Managed infrastructure (not a collection of existing, cheap access points) A service platform supporting: High bandwidth Mobility Positioning of devices Security 7
Current coverage 120 access points covering most of Midtbyen (downtown Trondheim) Integrated with NTNU Campus Network (1700 access points) Location-based services both in the city and on campus (Gløshaugen + Øya also indoors) Up to 5000 simultaneous users 8
Different mobile services relevant for Smart Cities -> Many dependent on location data Services for tourist, historical city guide Mobile learning services Services within entertainment, art, and culture, including social multiplayer mobile games Mobile, personalized news services Guiding persons to limit energy usage Services supporting out-door and in-door navigation and presense Travel support systems Tracking of equipment using RFID tags, city bikes Mobile health services, including mobile health monitoring Wi-Fi for video survilance, Emergency management 9 Core services, enabling secondary use of big data due to infrastructure to provide these services
10 Tracking city-bikes with RFID
11 City guide
Mobile Tourist Guide for Android Combine with recommender system to provide guidance based on other peoples interest. 12
13 MSIS Mobile Student Information System
From MSIS to the Campus Guide to Mazemap Common project betweentrådløse Trondheim A/S, Information department NTNU, Studieavdelingen, NTNU IT, NTNU Videre and IME NTNU Based on experiences developed through MSIS Cisco WLAN-positioning on Campus as in the City Originally released 31.August 2011 14

ICT in sustainabiliy society IKT som gjennomgripende tema Smart Cities beskriver hvordan man kan bruke IKT som aktiv del av byutvikling. Et kjerneområde for smarte byer er utnyttelse av allestedsnærværende sensornettverk i personlige applikasjoner og offentlige informasjonssystemer, samt aksept av ny teknologi som gjør oss i stand til å gjøre mer bærekraftige valg. bidra med analyser av faktiske miljøeffekter av nye teknologier, både på mikronivå og opp til makronivå for å studere konsekvensene av en større implementering av nye teknologier SO2 bærekraftig byutvikling Hvordan få tilgang til informasjon for å styre ressursbruk (menneskelige ressurser, transportressurser, energi, vann etc.) i byer på en måte som kan bidra til en bærekraftig byutvikling. Hvordan sikre at informasjonsinfrastrukturen i byer utvikles, forvaltes og brukes på en hensiktsmessig måte og i samspill med den øvrige byutviklingen, samtidig som personvernutfordringer ved instrumenterte byer ivaretas. 23
