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
IoT/Sensors
Performance
Capacity

Cloud Computing
• Location specific
• Resource
constrained,
• Expensive
(development/
deployment cost)
• Generally inflexible
(resource access and
availability)

• Location
independent
• Wealth of

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

Challenge: 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

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
Reasoning Algorithms
• Distributed and Heterogeneous Data Sources
• Diverse Data Streams
• Common Semantics Needed
• Solution: Semantic Annoitation (W3C
Ontology)
• 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 Background
Global Sensor Networks
Middleware (EPFL)
W3C Semantic Sensor
Networks (DERI, CSIRO)
• 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
• 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 ondemand 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 through
X-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 zeroprogramming interfaces
The tool enables validation and deployment
of the service

IoT Service Visualization
OpenIoT provides ready-touse mashup components
(mashup library)
Mashups are specified as part
of IoT service
