GENESI target is to fill the gap for long lasting or perpetual sensing systems, by designing and implementing a novel generation of “green wireless sensor networks” which can be embedded in buildings and infrastructures at the time of construction and be able to provide a monitoring and control intelligence over the whole structure lifetime. To achieve the above objectives GENESI combines advanced HW components (low power, flexible sensing platform equipped with a smart power unit and wake up radio capabilities) with novel energy efficient, energy harvesting and wake up radio aware communication paradigms, in-network distributed processing and reasoning mechanisms. The resulting system provides the core of the next generation of systems for structural health monitoring that are long lasting, pervasive, totally distributed and autonomous.

 

Key Achievements

  • The GENESI sensor node which combines a low power node platform with a multi-source energy harvester, a small factor fuel cell, and an energy efficient RF front end with radio triggering capability;

  • Energy-efficient interfaces with a variety of structural health monitoring sensors (vibrating strain gauges, displacement meters, pressure sensors, temperature sensors, soil moisture sensors);

  • Novel communication paradigms which are able to exploit at best the availability of the harvested energy (thanks to accurate multi-source energy prediction techniques) and the wake up radio features, and that are able to ensure reliable, long lasting communication of the measured data in real time, with little or no maintenance;

  • Novel distributed adaptive sampling and data aggregation mechanisms handling the trade-off between the data granularity, energy efficiency, and applications’ required quality of service;

  • Innovative distributed mechanisms enabling online situation awareness and adaptive learning based on artificial intelligence;

  • The integration of the above innovations into Solexperts WebDavies, resulting into a complete structural health monitoring system. The use of such system for monitoring two flagship infrastructure construction works: Rome B1 undergound (Rome, Italy) and Pont de  la Poya (Freuburg, Switzerland)
