IoT/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

Performance Capacity

Elasticity Utility-Driven

IoT in the

Cloud

IoT/Sensors

• Location specific• Resource

constrained, • Expensive

(development/ deployment cost)

• Generally inflexible (resource access and availability)

Cloud Computing

• Location independent

• Wealth of inexpensive resources

• Rapid elasticity• Flexibility



Sensor Clouds and Public 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

Open Source IoT Clouds:• OpenIoT

Challenge: Lack of Semantic Interoperability

• Including a syntactic harmonization of the data streams

• Use of CSV, XML, JSON format• Suitable for Intra-Enterprise Applications

Most Sensor Clouds focus on the integration of data streams

within the cloud

• 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

Lack of semantic

interoperability



Integrating silos in Smart Cities

The integration of the silos could maximize the ROI of the usually (costly) investments in

urban infrastructures



Ontologies for IoT Semantic Interoperability

Semantic Interoperability

• Distributed and Heterogeneous Data Sources• Diverse Data Streams• Common Semantics Needed• Solution: Semantic Annoitation (W3C

Ontology)

Reasoning Algorithms

• Intelligent Selection & Filtering of Sensors• Intelligent Selection & Filtering of Sensor

Data• Use of Reasoners• RDF/OWL Ontology (W3C SSN + Linked Data)Semantic Standards for sensors provide a

uniform way for representing and reasoning over heterogeneous data streams

OpenIoT BackgroundGlobal Sensor Networks

Middleware (EPFL)

• Widely used streaming data database

• Available as Open Source Software

• Supports multiple sensors via a Virtual Sensor Interface

• In OpenIoT used as a hub to the physical world

• Provides sensor virtualization and supports virtual sensors and sensor fusion

W3C Semantic Sensor Networks (DERI, CSIRO)

• Outcome of the W3C SSN Incubrator Group (DERI, CSIRO)

• SPARQL used for quering and event detection

• Defines ontologies and techniques for sensor selection, sensor data selection, tasking & programming

• Semantically Anotated Sensors and ICO Resources

• Supports several of the on-demand concepts in OpenIoT

• Implemented through Linked Sensor Middleware (LSM)

Sensor Clouds (AIT, EPFL)

• Integrating sensors/ICO/WSN with cloud computing infrastructures

• GSN-Cloud infrastructure integration towards a «Sensor Cloud»

• OpenIoT has carried out experiments with popular cloud infrastructures (SimpleDB, Hbase, Cassandra over Amazon Cloud)

ICO Integration, Deployment and Registration

OpenIoT can integrate virtually any ICO throughX-GSN

Support for both physical sensors (e.g., cameras, microphones, temp etc.) and virtual sensors (e.g., algorithms, 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



Dynamic Sensors/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 dynamic access of both sensor data and meta-data



Visual IoT Service Definition

OpenIoT provides the means for synthesizing the data of selected sensors/ICOs 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

Select Sensors/ICOs Filter & Combine Sensors/ICOs

Select Sinks for Visualization/Presentation

Validate & Deploy on OpenIoT middleware



IoT Service Visualization

OpenIoT provides ready-to-use mashup components (mashup library)

Mashups are specified as part of IoT service specification/generation

Integrators can override the mashups with their preferred presentation components
