About

The SensibleThings platform is a platform for creating fast and efficient Internet-of-Things applications, connecting sensors and actuators to varius types of applications. This website exposes and describes the SensibleThings open source platform for application development, which is a product from research done at Mid Sweden University. The platform is developed in collaboration with partners from both industry and academia. In detail, it is fully licenced under the GNU Lesser General Public License Version 3, which enables commercialization of third party products built on top of the platform.

The basis of the idea and the source code, is a fork of the previous MediaSense open source platform but has been severly improved since then. In detail, MediaSense was an EU-funded project between 2008 and 2010 at Mid Sweden University which addressed the intelligent delivery of sensor based information to any host, anywhere. Many of the current developers of the SensibleThings platform was a part of the MediaSense project, but has now decided to continue to work on the platform under the new name.

Technical Overview

The SensibleThings platform can be divided into different layers with ingoing components. These layers include an interface layer, an add-in layer, a dissemination layer, a networking layer, and a sensor/actuator layer. The interface layer is the public interface through which applications interact with the SensibleThings platform. The add-in layer enables developers to add optional functionality and optimization algorithms to the platform. The dissemination layer enables dissemination of information between all entities that participate in the system and are connected to the platform. The networking layer enables connection of different entities over current IP based infrastructure. And finally, the sensor and actuator layer which enables different sensors and actuators to connect into the platform.

To be specific, the SensibleThings platform builds on the following technical principles: IP based communication on work on the current Internet, become globally scalable by employing a fully distributed DHT architecture, have P2P communication that sends data in the first packet, using NAT penetration techniques for seamless networking, and have a lightweight implementation to run on limited devices. All these are solved by the open source LGPLv3 licensed Java code, a choice between a Kelips or a Chord DHT, reliable UDP or SSL communcation, distributed proxies when UPnP fails, and connecting sensors and actuators directly via the Java code or via the CoAP protocol.
