In a fast-paced changing world due to major advances in computing and networking technologies, the global pandemic and its repercussions (Social distancing,Lockdowns...) made humanity rely more than ever on the Internet to achieve all kinds of daily tasks (shopping, remote work etc.). It was a natural consequence tosee technologies that help automating tasks being quickly adopted; in the image of Internet of things, one of the most benefiting areas from those advances [6].Indeed, the increasing computing power and storage capacity, meanwhile with the reduction of semiconductors node size allowed the creation of tiny MCUs(Micro Control Unit) which can be embarked in almost anything. Such a technological feature enables communication through heterogeneous networks, for the purpose of collecting, storing and processing data. This resulted in a quick appearance of multiple kinds of smart connected devices in almost every area,from the industrial sector known as the Industrial Internet of Things (IIoT) to

It is expected that, in a mid term, smart connected devices will be more integrated in each aspect of people’s every day’s life, not only because those devices are becoming cheaper and more accessible to a large number of persons world-wide, but also because individuals are becoming more aware of the potential of this technology in making their day-to-day tasks easier to complete in the mostefficient possible way. Studies show that the number of IoT devices is expected to exceed 70 billions in the next three years, which highlights the quick adoption of this domain worldwide.
