Transcript

  • 1. Naming, Search and Discovery in IoTIssues and proposed solutionsin the FP7 EU IoT.est Project
  • 2. IoT.est – a quick 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 andinstantiate IoT services that exploit data across domain boundaries;• IoT.est will facilitate run-time monitoring and will enable autonomousservice adaptation to environment/context and network parameter(e.g. QoS) changes.
  • 3. IoT.est: The Key issues• 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 ScaleDeployment• Testing (Design Time): Automated Generation of Tests• Monitoring (Run-Time): Context-aware Service Adaptation
  • 4. Consortium• 8 partners, 7 countries• Project Lead:CCSR, University of Surrey• Started in:October 2011Industry PTIN, ATOS, SIESME TT, AIResearch Centre NICTHigher Education UNIS, UASO
  • 5. IoT.est• IoT + SOA + Test– Our focus is on IoT-enabled SOA + Test• IoT.est will not implement another IoT platform– We assume low-level connectivity, information communication anddevice-level services are provided by other IoT platforms.– We work on IoT-enabled service life-cycle support and brining “Test” toIoT service and system design, implementation and deployment.• However, naming and discovery is also an issue for IoT.est.
  • 6. Naming and Discovery issues• How to name, find and access the IoT resources,services and test/service modules.– Service designers need to know:• What resources are available• Where they come from• How to access them– We consider using reusable test components to evaluate and/orvalidate:• Availability• Reliability• Adaptability• …
  • 7. Using semantic data• Semantic data for modelling and describing– Resources• Gateway, sensors, processing resources– Entities• Physical world objects– Features of interest for each entity– Services• IoT services and interfaces– Test functions and test modules• (semantic) TTCN3?
  • 8. IoT.est ontology- first draft5/9/2012 Confidential 8
  • 9. Linked data approach• IoT resources will be addressed by a URI.• By referring to a URI, we will be able to receive meaningfulinformation about a resource (semantic annotation).• A URI will define the service interface to interact with IoTresources.• The low-level name resolution could be handled by other existingframework or component or an abstraction layer in the case of6LowPAN and CoAp.– directly (with some intermediaries)– or on other non-IP platforms we need an overlay layer or amiddleware (gateway) to represent the IoT resources (virtualisation).
  • 10. Discovery• IoT.est will provide an integrated semantic annotation framework todescribe IoT resources, entities, services and test functionalities.• The search and discovery will be based on the attributes of theresources/entities and services described in the semanticannotations.• So this will be more a semantic search and reasoning issue.
  • 11. What are the practical steps?• Linked data approach is a promising way of integrating data fromdifferent sources and interlinking semantic descriptions.• Alignment between different description models for IoTServices/Resources/Entities;• Proposing reference and abstract models for semantic descriptionsin IoT (e.g. similar to W3C SSN approach).• However, semantic data processing is not often easy in resourceconstrained environments (such as IoT)– Binary RDF or N3 could be potential solutions.• Distribution of resources and scalability of solutions are also otherkey challenges.
  • 12. Thank you!
