Smart Cities Market Source: Frost & Sullivan “Global Smart City Market – A $1.5 Trillion Market Opportunity by 2020”, Market Report, September 2013. Expected market growth: From $6.1 billion annually in 2012 to $20.2 billion in 2020 (i.e. 16.2% CAGR) Dominant Areas: Energy, transportation, government 7

Smart Cities and Internet of Things Smart Cities are based on broadband and IoT infrastructures (e.g., sensors) Smart City Applications Handle Data Streams (from different information), and deal with multiple events Smart Applications (Smart Home, Smart Transport, Smart Buildings, Smart Police Activiies,...) Environment for Integrated Surveillance (leverage sensors from municipalities, city authorities, community sensors...) 9

Maturity Models Phase 1 – Digital Phase 2 – Phase 3 – Infrastructure Services Services Development Integration & • Broadband Networks Citizens Sensor Networks, • Smart Energy, Smart (Public Open Data) Participation Transport, Urban • Certification & Mobility • Integration and Validation of • Stakeholders’ Reusability of Data & Infrastructures Involvement Services • Digital City • “Smart City” • Citizens’ Engagement • Integrated Smart City 11

Challenge: Smart Cities Silos Integration The integration of the silos could maximize the ROI of the usually (costly) investments in urban infrastructures 12

ΙοΤ / Cloud Convergence • Convergence IoT Between IoT and Cloud Computing – Allow IoT applications to leverage the benefits of the Cloud • Challenge – Conflicting properties of IoT (e.g., WSN) and Cloud IoT/Sensors Cloud Computing Performance Capacity • Location specific • Location • Resource independent • Wealth of constrained, IoT in the inexpensive • Expensive Cloud resources (development/ • Rapid elasticity deployment cost) • Generally • Flexibility inflexible (resource access Elasticity Utility-Driven and availability) 13

Sensor Clouds and IoT Clouds • Streaming of Sensor / WSN data in a cloud infrastructure (2005-2009) (Mainly Research Efforts) • Advent of Public IoT Clouds (2007+ including commercial efforts) e.g.,: – Xively (xively.com) – ThingsWorx (www.thingworx.com) – ThingsSpeak (thingspeak.com) – Sensor-Cloud (www.sensor-cloud.com) – Realtime.io (https://realtime.io/) – ... And many more 14

Lack of Semantic Interoperability • Most Sensor Clouds focus on the integration of data streams within the cloud • Including a syntactic harmonization of the data streams • Use of CSV, XML, JSON format • Suitable for Intra-Enterprise Applications • Lack of semantic interoperability • Foundation for Inter-Enterprise Applications in global IoT • Common Semantics – Uniform / Global Discovery of IoT Resources • Foundation for Integrated Smart City Applications that bridge existing silos 15

Ontologies for IoT Semantic Interoperability Semantic Interoperability Reasoning Algorithms • Distributed and Heterogeneous Data Sources • Intelligent Selection & Filtering of Sensors • Diverse Data Streams • Intelligent Selection & Filtering of Sensor Data • Common Semantics Needed • Use of Reasoners • Solution: Semantic Annoitation (W3C • RDF/OWL Ontology (W3C SSN + Linked Semantic Standards for sensors Ontology) Data) provide a uniform way for representing and reasoning over heterogeneous data streams 16

What can I do with OpenIoT? Visual IoT Service Definition & IoT Service Deployment Dynamic Visualization Sensor/ICO (via Discovery Mashups) Sensor/ICO Resource IoT Platform Deployment Management Architecture & & and Capabilities Registration Optimization 20

Sensor & ICO Registration OpenIoT can integrated virtually any ICO through X-GSN Support for both physical sensors (e.g., cameras, microphones, temp etc.) and virtual sensors (e.g., algorithm, twitter streams) If a low level is available the process involves editing a simple metadata file Impelementation of drivers for not supported sensors is a matter of 1-2 man days effort Deployed ICOs publish their data according to OpenIoT (W3 SSN) ontology via LSM 21

Dynamic Sensor & ICOs Discovery Dynamic ICOs and Sensors Look-up Takes place through the Scheduler Discovery Citeria including ICO/sensor type and location The Discoverer component (LSM) is deployed in the cloud SPARQL is used for accessing both sensor data and meta-data (dynamically) 22

Visual IoT Service Definition & Development OpenIoT provides the means for dynamically selecting sensors/ICOs and synthesizing their data into services The «Request Presentation» visual tool (part of OpenIoT IDE) provides a zero- programming interfaces The tool enables validation and deployment of the service Filter & Combine Select Sinks for Validate & Deploy on Select Sensors/ICOs Sensors/ICOs Visualization/Presentation OpenIoT middleware 23
