Interoperability and Open Source Workshop

i3-MARKET chaired a workshop,  co-located with the 11th International Conference on the Internet of Things (IoT 2021), that focused on Interoperability and Open Source Software Solutions for European businesses.


The evolution of the Internet of Things has created a complex ecosystem populated by various Internet of Things (IoT) platforms that provide access to a broad range of things. These IoT platforms typically promote their specific interfaces and information models, and often adopt non-standard, sometimes fully proprietary, protocols to control a variety of things. This fragmentation and missing interoperability currently prevent the emergence of cooperative IoT ecosystems in which applications can be built to simply use things, or to enable things operated by different platforms to interact.


The 4th Workshop on Interoperability and Open-Source Solutions for the Internet of Things focused on addressing this challenge, bringing together the community of industry players, stakeholders and open source communities. The main objective of the event was to exchange experiences and ideas with the IoT and Data communities as well as contribute to build new knowledge analyzing open issues and identify gaps on interoperability, architectural principles, marketplaces and standardization for future. It featured the voice of industrial experts, by providing an environment where attendees (presential or remotely) had the opportunity to explore interoperability solutions stemming from research and innovation projects and showcase practical experiences on interoperable IoT solutions and promote open-source solutions.


The 2021 InterOSS – Interoperability and Open Source Solutions Workshop paper will be online in due course.

The authors and their papers are below:

Dr. Helmi Ben Hmida, T-Systems International – IoT & Digital Transformation Expert – Senior Program Manager

Industrial keynote Central Topic: Paper KS1: IoT & Digital Transformation: Challenges and Opportunities

Dr. Helmi Ben Hmida spoke about the current challenges that Digital Transformation impose over the current Technologies and Markets. After managing several large scale IoT projects touching several verticals and domains (City, health, building, mobility, weather, work…etc. ), Dr. Helmi Ben Hmida believes that a successful Digital\IoT business needs some characteristics that are the baseline for success. Based on his experience, Dr. Helmi Ben Hmida provided a vision on the Opportunities for progressing the state of the art with technologies like Big Data, IoT and AI.
