Transcript of "Tools for the Open Source Internet of Things"

  1. 1. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 1 Tools for the Open Source Internet of Things IoT Toolkit Smart Object API
  2. 2. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 2 Open Avenues for Participation ● Traditional manufacturer-consumer roles disrupted; Customize Your Life is the new DIY ● Global innovation cycle is limited by serialized secret design iterations and fear of lawsuits, improved by early and often interaction during design protovation ● Industry SIGs limit participation to conforming entities ● Traditional IP trade for equity system limits access of individuals to their own work, we need new equity value models ● The Internet of Things will out-scale and out-last any walled garden; what we need is an open ecosystem based on individuals being the seat of control for their own data, experience, and contribution
  3. 3. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 3 Open Source Ecosystem ● What is a Platform? Developers and users sharing resources, who controls it? ● What is an Infrastructure? Communities of developers and users sharing resources, who controls it? ● What is an Ecosystem? Communities interacting around co- development of shared resources, community controls it. ● What is meant by “open” in which context? Is there a single source element in the system? Who controls the access? ● What is Open Source? Free speech vs. lunch, Open Source == Multiple Source ● What is an Open Source Ecosystem? Open Avenues of Participation at all levels
  4. 4. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 4 Internet of Things ● Network of Sensing, Reasoning, and Action ● Context Aware, Real-Time and Hyper-Local, Granular Scale ● Integrating physical sensors and other data sources, connecting the physical world to the virtual world ● Consists of Physical Graph and Social Graph: People connecting to things, things connecting to things, people connecting to people
  5. 5. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 5 IoT Early Deployment ● Sensors and Actuators => Gateway or Hub => Cloud Service ● Vertical integration around one primary vendor ● Each vendor has a variation of REST-like API ● No high level opportunistic integration between vendors ● Single source lock-in strategies even for “open platforms”, typical is open source client + single (closed) source service i.e. freemium style services ● Too many services for users to manage
  6. 6. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 6 IoT Application is a Graph ● IoT applications will consist of graphs ● Sensors, acuators, and informing devices at the edges ● Processing (rules, logic, filtering, aggregation) at the nodes ● Linked according to user intentions ● Many connections, vertical, horizontal, diagonal ● Redundancy through a rugged overlay network ● Data push-on-update for scalability
  7. 7. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 7 IoT Application is a Graph Sensors User Input Data Sources Application Logic Services and Gateways Actuators Storage User Display
  8. 8. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 8 Semantic Web ● Nodes in the IoT application graph are linked by semantic compatibility, e.g. data types and physical types ● Semantic Web provides mechanism for discovery and linkage of appropriate nodes by type compatibility ● Self-describing data from ontologies ● Dynamic API to data types ● Drives high degree of articulation from simple resource based RESTful API ● Replication and persistence formats, Big Data compatible
  9. 9. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 9 Smart Object API Smart Object API based on Semantic Web Linked Data resource description and a simple set of resource types making up a Virtual Object: ● Description: The Linked Data describing the Object's resources, it's structure, and data types ● Observable Properties: The encapsulated data types e.g. time+location data stream ● Observers: dynamic links for data updates to be pushed (http POST/PUT, CoAP obs, MQ, PubSub) ● Agent: Software process to invoke on data updates
  10. 10. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 10 Smart Object Encapsulation of API Resources Description Observable Property Observers Agent HTTP Interface CoAP Interface Application software Agents handle state changes and application logic, including filtering and aggregation Maps updates to HTTP POST, MQTT, PubSub Data type encapsulation with description RDF describes resources, structure, types, and Linked Data <=> CoAP RD proxy

  13. 13. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 13 IoT Toolkit: Gateway + Service GaaS ● Constrained network gateway supporting multiple Wireless Sensor Nets (WSN) ● Using CoAP as a sensor abstraction layer, create Resource Description for each sensor using core-link-format and IPSO application concepts from link-format compatibility ontology. ● HTTP LD <=> CoAP RD Semantic proxy ● Service and gateway use same reference implementation and API ● Software Agents and Resources may be replicated across gateways and services for redundancy ● Creates a compatibility layer for sensor nets and services
  14. 14. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 14 Closed Gateway INTERNET IoT MULTI- PROTOCOL GATEWAY Multiple Sensor Nets, Constrained Protocols IoT Gateway- as-a-Service Service API IoT “Silo” or other data source Cloud Apps Gateway Apps IoT Toolkit IoT Applications run in Cloud or on Gateway
  15. 15. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 15 Access Control ● Rethinking of access control for granular interaction between people and things ● Based on social graph connecting to physical graph ● FOAF connects people to people ● SSN, O&M, IoT ontologies will connect things to things and define situations and context ● FOAT ontology is proposed to connect people to things with concepts of individual authority
  16. 16. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 16 Ontologies ● Ontologies define the data architecture of these systems ● This system needs various ontologies to drive the interactions and propagate new constructs – SSN, IoT, O&M define sensing, actuation, situations – SmartObject to define resources in the SmartObject API – LinkFormat to map CoAP RD to Linked Data – FOAT to define relationships between people and things – IoTServices to define services e.g. SPARQL, MapReduce endpoints
  17. 17. 12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 17 IoT Toolkit Project ● Reference implementation work in progress using Python, rdflib, restlite ● Reference platforms Raspberry Pi + Ciseco EVE multi-WSN, Ubuntu micro-instance GaaS ● Xbee, Z-Wave, EnOcean, XRF, RFM12B on board, BT, WiFi, etc using USB plugs ● To Do: Document+Test complete API, high level semantic patterns, ontologies, sensor nets, service functionality e.g. SPARQL endpoint, MapReduce
