IoT Broker

IoT Broker is the FIWARE reference implementation by the IoT Broker Generic Enabler by NEC. The source code of this implementation is published via the GitHub repository Aeronbroker/Aeron.

The IoT Broker is an Internet-of-Things middleware based on the FIWARE NGSI standard. It is provided by NEC Laboratories Europe as part of their contribution to the European Future Internet Platform FIWARE.

Directory Structure

Most of the below sub-directories are containing source code for OSGi bundles the IoT Broker runs with. Some of these bundles are required for a working installation of IoT Broker; others are implementing optional features and do not need to be deployed when these features are not needed. In addition, this repository also contains an OSGi runtime environment and pre-configured startup script for the IoT Broker, as well as a blackbox test utility for testing a running IoT Broker instance.

Directory Contents

├── eu.neclab.iotplatform.iotbroker.embeddediotagent.core Optional bundle for enabling storage and retrieve of (historical) context information.
├── eu.neclab.iotplatform.iotbroker.embeddediotagent.couchdb Optional bundle for enabling the storage of the (historical) context information into CouchDB. (This bundle must be activated if eu.neclab.iotplatform.iotbroker.embeddediotagent.core is active).
├── eu.neclab.iotplatform.iotbroker.embeddediotagent.indexer Optional bundle for indexing the (historical) context information (This bundle must be activated if eu.neclab.iotplatform.iotbroker.embeddediotagent.core is active).
