  1. 1. Tools for the Open Source Internet of Things IoT Toolkit Smart Object API12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 1
  2. 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 contribution12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 2
  3. 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 levels12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 3
  4. 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 people12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 4
  5. 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 manage12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 5
  6. 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 scalability12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 6
  7. 7. IoT Application is a Graph Sensors Application Actuators User Input Logic Storage Data Services and User Sources Gateways Display12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 7
  8. 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 compatible12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 8
  9. 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 Objects resources, its 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 updates12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 9
  10. 10. Smart Object Encapsulation of API Resources HTTP Interface CoAP Interface Application software Agents handle state RDF describes resources, changes and structure, types, and Linked Agent Data <=> CoAP RD proxy application logic, including filtering and aggregation Description Observers Maps updates to Observable Data type HTTP POST, MQTT, Property encapsulation PubSub with description12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 10

  13. 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 services12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 13

  15. 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 authority12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 15
  16. 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 endpoints12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 16
  17. 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, MapReduce12/12/2012 Michael J Koster Tools for the Open Source Internet of Things 17
