Worldwide deployed power grids have provided seamless unidirectional power supply of electricity for decades. Recently, diverse environmental factors (e.g., depletion of primary energy resources, climate change) and the heterogeneous nature of energy production are calling for new solutions. Accordingly, the Smart-NRG project proposes a modular and flexible system architecture, new technologies, and...
Power grids deployed in every city worldwide have served relatively well in providing power supply of electricity. Nevertheless, today a new set of challenges is arising, such as the depletion of primary energy resources, the diversification of energy generation and the climate change. Traditional power grids are rapidly evolving into a new form under the name of smart grids, which encompass new technologies...
Contemporary technologies as implemented in the field of healthcare have provided the everyday clinical practice with a plethora of tools to be used in various settings.

Life expectancy is projected to increase significantly in the coming years. This fact has pushed the need for designing new and more pervasive healthcare systems. In this field, distributed and networked embedded systems, such as Wireless Sensor Networks (WSNs), are the most suitable technology to achieve continuous monitoring of aged people for their own safety, without affecting their daily activities...
The increasing usage of wireless sensor networks in large scale and safety critical monitoring applications scenarios exacerbates their well known energy and scalability limitations. Organizing the network in clusters is what the most of the existing solutions propose to dominate network complexity, as well as to define quality of service policies in charge of fitting application requirements. However,...
This paper describes a new industrial case on automation, for large‐scale systems with high environmental impact: the mining ventilation control systems. Ventilation control is essential for the operation of a mine in terms of safety (CO and NOx regulation) and energy optimization. We first discuss a novel regulation architecture, highlighting the interest for a model‐based control approach and the...
Mining ventilation is an interesting example of a large scale system with high environmental impact where advanced control strategies can bring major improvements. The challenge in this work is focused on the mining ventilation since as much as 50 % or more of the energy consumed by the mining process may go into the ventilation (including heating the air). It is clear that investigating automatic...
We propose a comprehensive theoretical framework to evaluate reliability and energy consumption of distributed source coding (DSC) in wireless sensor networks (WSNs) applications. Energy efficiency and the amount of measurements that can be successfully decoded in tree-based WSNs employing DSC in the presence of different coding topologies and packet aggregation schemes (PA) are accurately characterized...
