OpenSensorHub

Introduction

What is it?

OpenSensorHub is a collaborative open source software package for supporting easy deployment and access to sensor, actuators and processes on the web.

It is compliant with OGC® SWE standards but also supports other IoT standards such as MQTT.

It can be used and extended to build smart and scalable sensor networks.

Objectives

  • Implement the whole SWE vision: Dynamic, Generic
  • Enable Auto-Configuration of SWE service interfaces
  • Hide the complexity and make it easy to build on-top of SWE
  • Make it easy to develop new sensor drivers
  • Allow efficient live data streaming and stream processing
  • Support multiple platforms (especially embedded)
  • Not limited to SWE, Integrate with IoT protocols such as MQTT
  • Does not reinvent GIS tools but rather integrate with them

Main Features

  • Connect ANY sensor/actuator and store/view collected data
  • Deploy standard web services
    • Access archive data and/or live sensor data streams
    • Send commands to sensors and actuators
    • Process live streams or historical data
  • Interconnect OSH instances to form larger networks
    • ​Via classical HTTP services and WebSockets
    • Via IoT protocols (e.g. MQTT)
    • Via P2P overlay networks (roadmap)
  • Integrate with Mapping Servers (e.g. Geoserver)
  • Configure using modern web UI

Supported Platforms

Fine-Grained Permission Based Access Control

  • Each module can define its own set of permissions
  • Permissions are then assigned to users and roles via pluggable realm implementation
  • Default realm implementation provided in core

 

TODO: Anti-Spoofing and better DoS protections

Reliability

Testing and Code Coverage

As much unit tests as possible

More automated tests of various OSH setups (CI)

 

Robustness to Connectivity Issues

Robustness to network outages

Robustness to device and service disconnections

 

Multi-Threading for Performance and Error Isolation

Each module runs in its own thread

24/7
