2 Open Source Eclipse IoT Projects Released Ahead of EclipseCon 2015
The San Francisco edition of the Eclipse Foundation's user conference, EclipseCon 2015, gets under way next week (March 9-12). I'm looking forward to catching some sessions and keynotes on a range of topics, but I'm particularly intrigued by the foundation's activities around the Internet of Things (IoT). The Eclipse IoT momentum just keeps building. In fact, two open-source projects that are part of that effort, Eclipse Paho and Eclipse Mosquitto, announced new releases this week.
Both projects -- Paho 1.1 and Mosquitto 1.4 -- implement the client and broker for the OASIS Message Queuing Telemetry Transport (MQTT) protocol. The MQTT protocol is designed to connect physical world devices and networks with applications and middleware. It has been widely adopted by IoT solution providers, largely because of its small footprint, minimal bandwidth requirement for messages, and its ability to adapt to unreliable network connections -- all essential qualities for an IoT protocol.
Ian Skerrett, the Foundation's vice president of marketing, who has been leading the Eclipse effort to foster an open-source community around IoT, told me that providing open-source implementations of MQTT has been something of a project focus. Interest in these two projects in particular has been high in the community, Skerrett said in an email, and the Foundation considers their release to mark "a pretty big milestone."
The Eclipse IoT Project aims to establish an open platform for IoT and machine-to-machine (M2M) communication that combines a set of services and frameworks, open-source implementations of standard protocols, and an Eclipse-based IDE for IoT/M2M development.
The Paho Project provides scalable open-source client implementations of open and standard messaging protocols for IoT/M2M apps. New in this release: support for .NET, WinRT, and Android clients; C and C++ libraries for embedded clients; updated versions of the Java, Python, and JavaScript clients to conform to the MQTT 3.1.1 standard. The new version is available for download now.
The Mosquitto project provides an open-source implementation of an MQTT broker. New in this release: easier integration with web sites through support for WebSockets; more flexible support for TLS v1.2, 1.1 and 1.0 f or enhanced security, plus support for ECDHE-ECDSA family ciphers; improved interoperability between MQTT brokers via better bridge support, including wildcard TLS certificates and conformance to MQTT 3.1.1. The new version is also available now for download.
"In the last year we have seen tremendous interest in the Eclipse IoT community, and in particular Paho and Mosquitto," said the Foundation's executive director Mike Milinkovich, in a statement. "Forty developers contributed to the new Paho and Mosquitto releases, demonstrating incredible interest for these projects and MQTT in general."
The Eclipse IoT project has evolved fairly quickly into a full-fledged community that is currently 15 projects strong. In addition to the MQTT protocol, those projects implement Lightweight M2M and CoAP, as well as several IoT-friendly frameworks.
