Flexible IoT middleware for integration of things and applications

The Internet of Things (IoT) is a rapidly growing system of physical sensors and connected devices, enabling an advanced information gathering, interpretation and monitoring. However, IoT must be supported by a middleware that allows IoT consumers and IoT application developers to interact in a user-friendly way, despite the differences in each user´s perspective of IoT system. To that end, our software attempts to bridge the gap between IoT consumers and IoT application developers. Through the coupling of GSN (an existing open source IoT middleware), Firebase (a cloud storage service), and an IoT data interpreter developed by us, we have created a software system that takes the first step towards an ubiquitous middleware for IoT.
