Introduction ▪ Actuators are essential to IoT Applications

  • Smart Homes
  • Smart Industry
  • Smart Transportation
  • Healthcare

▪ Change their physical environment

Challenges ▪ Diversity

  • Different devices
  • Different implementations
  • Different command protocol

Generic Actuation ▪ What?

  • Control any actuator
  • Independent protocol
  • Independent manufacturer

▪ How???

Our Approach ▪ Taxonomy of Actuation

  • Blind
  • Reliable with active feedback
  • Reliable with passive feedback
  • Noticeable with indirect feedback
  • Noticeable with indirect and delayed

feedback

Our Approach ▪ ContextNet Extension ▪ M-ACT

  • Microservice of M-Hub
  • Request drivers for the actuators
  • Translates generic commands to native protocol of actuators

▪ SOM (Smart Objects Manager)

  • Microservice of the ContextNet Core
  • Repository of drivers
  • List of devices registered
  • ConnectedTable

▪ Drivers to describe the native protocol

Driver

▪ JSON format

Device type and communication interface it uses Connection Steps (e.g. To unlock the device) List of available commands in a generic format and the specificationto translate to the native protocol

Tests ▪ Demostrate the feasibility of our approach ▪ Control the Toy Robot BB-8 ▪ Evaluate the overhead added

  • Average ~36ms added to translation

Conclusions and Future Work ▪ Demostrated the feasibility of the approach ▪ Mobile gateways can incur in actuation failures due to disconnection ▪ Suitable for smart homes, smart buildings, and systems where realtime are not required
