Outline

• Virtualising the real world

– the iCore approach to using real objects and creating RWO enriched services in the IoS

• The issues with service creation

– RWOs as service components

– IoT.est service testing

the iCore approach

• VO fabric creates and manage the semantic description of VOs

• cognitive mechanisms in the VO factory are used for objects awareness and maintain the handle to VO

• service logic instantiates the reconfigurable application on the CVO fabric

• CVO fabric looks up and discovers appropriate VO/CVO or deploys mechanisms for composition of new CVOs

• cognitive mechanisms are used to create the service logic based on the user/application requirements and preferences

issues in service creation (with RWOs)

• Service components

– availability

– stability

– usability

– …

• Service composition

– integration and interoperation

– testing before deployment

Internet of Things Environment for Service Creation and Testing (IoT.est)

IoT.est- Bridging the gap

Process Automation Framework

IoT.est – a snapshot

• IoT.est will develop a test-driven service creation environment (SCE) for Internet of Things enabled business services.

• The SCE will enable the acquisition of data and control/actuation of sensors, objects and actuators.

• The project will provide the means and tools to define and instantiate IoT services that exploit data across domain boundaries;

• IoT.est will facilitate run-time monitoring and will enable autonomous service adaptation to environment/context and network parameter (e.g. QoS) changes.

IoT.est and Service Frameworks

• IoT enabled Business Services: Semantic Description

• Service Composition: A Knowledge based Approach

• Service Components: Re-usable, Interoperable and Adaptive

• Abstraction: Mapping to Heterogeneous Platforms and Large Scale Deployment

• Testing (Design Time): Automated Generation of Tests

• Monitoring (Run-Time): Context-aware Service Adaptation

Targeted outcomes

• Methods to derive semi-automatically services and related tests from semantic service descriptions based on standard service interfaces and re-usable service and test components.

• Integrating testing into a Service Creation Environment supporting incremental service evolution by regression tests.

• Definition of a framework for service validation tests in a sandbox environment before deployment in the service provider’s infrastructure, including automated deployment procedures based on semantics for service resource requirements and network capabilities.

• Development of run-time monitoring mechanisms which enable service adaptation to environment changes and to adjust network parameters (e.g. Quality of Service).
