The Eclipse sensiNact project consists of a software platform enabling the collection, processing and redistribution of any data relevant to improving the quality of life of urban citizens, programming interfaces allowing different modes of access to data (on-demand, periodic, historic, etc.) and application development and deployment to easily and rapidly build innovative applications on top of the platform.
Internet of Things
Technology that supports wired or wireless communication between machines.
Eclipse Ditto is the open-source project of Eclipse IoT that provides a ready-to-use functionality to manage the state of Digital Twins. It provides access to them and mediates between the physical world and this digital representation.
IoT solutions have to interact with a heterogeneous set of device types, device protocols and communication patterns.
The Eclipse Agail is a language-agnostic, modular software and hardware gateway framework for the Internet of Things with support for protocol interoperability, device and data management, IoT application execution, trusted data sharing and external Cloud communication.
The Eclipse ioFog set of technologies is a fog computing layer that can be installed on any hardware running Linux. Once installed, it provides a universal runtime for microservices to run on the edge. In addition to a common runtime, ioFog also provides a set of useful services including a message bus, dynamic configuration of the microservices, and remote debugging.
Eclipse Unide provides a lightweight Production Performance Management Protocol (PPMP) server-client implementations (using JSON, REST and other). The core of the protocol are two interface definitions:
- PPMP Measurement Interface: This is a public REST API with the purpose of receiving time series and machine data.
- PPMP Messages Interface: This is a public REST API with the purpose of receiving machine messages.
The following diagram provides a functional architecture of the Eclipse Kapua project.
The connectivity of the devices is managed through a multi-protocol message broker. In the initial contribution, the protocol for the device connectivity will be the IoT protocol MQTT. The broker supports other protocols including AMQP and WebSockets for application integration.
OPC Unified Architecture is an interoperability standard that enables the secure and reliable exchange of industrial automation data while remaining cross-platform and vendor neutral. The specification, currently version 1.03, is developed and maintained by the OPC Foundation with the guidance of individual software developers, industry vendors, and end-users. It defines the interface between Clients and Servers, including access to real-time data, monitoring of alarms and events, historical data access, and data modeling.
The edge devices connected to the Cloud that constitute the Internet of Things (IoT) require support for building blocks, standards and frameworks like those provided by the Eclipse Foundation projects: Californium, Paho, Leshan, Kura, Mihini, etc.
Because of the large deployment of Java technology in the Cloud, on the PC, mobile and server sides, most projects above are implemented in Java technology.
