WP4 of the BRAIN-IoT project deals with Decentralization of IoT platforms and services. In this presentation you will find a description of the approach and current status of the project in the following topics: 1. Repository & Runtime Decoupling 2. Platform Foundations 3. Federation

1. 1
• Repository & Runtime Decoupling
• Platform Foundations
- Leveraging Paremus Service Fabric & sensiNact IoT agent.
- Installing Smart Behaviour
• Federated:
- A Brain-IoT Environment may be comprised of a number of local Autonomous
platforms that can co-operation on site, or geographically distributed.

WP4 - Fabric / sensiNact work
• A cut down deployment of sensiNact capable of running in a “vanilla” OSGi launcher
• An updated northbound REST connector using the OSGi Http Service Whiteboard
• A simple “smart lightbulb" example with a REST based web ui
• A generated system to deploy these things on the Service Fabric

To Do - D4.2
• Separate the northbound gateway bundles from the Southbound device invocation/connector bundles
• Physically separate the northbound gateway REST UI from the southbound device by running the two in separate OSGi frameworks
• Use OSGi Remote Services for communication between the gateway framework and the device framework
• Allow one gateway to communicate with multiple device frameworks
• Update the generated system to deploy this onto the Service Fabric

WP3 / D3.3 - Dynamic Install
Dynamic Install of Smart Behaviours:
• Push Install on Command - (EMALCSA?)
- Install specified Smart Behaviour
- Update specified Smart Behaviour (a later trained Network)
• Self Configuring Edge - Pull Smart Behaviour based on Edge Type - (Robotnik)
- I’m a Robot - search repo and install Robot behaviour
- I’m a Door Edge Node Proxy - search repo install Door Controller Behaviour
- I’m the Orchestrator - search repo install Orchestration Behaviour.
• Adaptive Edge - Environmental Event Trigger (D4.1 See discovery pipeline).
- A new Discovery Event is unknown / cannot be processed by Edge Node
- Edge installs required Smart Behaviour

11. 1. Move completes, notifies behaviour
2. Behaviour enters “Door” state and requests the door be opened by sending an event to
the local broker
3. Local Broker determines a remote broker has interest and sends the event
4. Event is delivered to the interested party (the orchestrator)
5. The orchestrator decides the door must be opened and sends an event to the local
broker
6. Local Broker determines a local interest and delivers the event to the door behaviour
7. The door smart behaviour triggers the door connector
8. The door connector tells the door to open
9. When the door is open the door behaviour sends a “door open” event to the local broker
10. The local broker delivers the event to the locally interested party
11. The orchestrator behaviour creates a notification event for waiting robots
12. The broker determines a remote interested party and delivers the event
13. The robot behaviour receives the door open event, and moves back to the moving state
14. The robot behaviour requests that the robot begin moving.
