Résumé
The Internet of Things is a promise of smarter technologies, with devices working together in a distributed manner, to provide more quality of service in many domains, such as industry, transports, energy, health, etc. Fog/Edge computing is probably one of the most interesting concepts as it will be a means to optimize energy and performance. However, beyond the principle, few works have really demonstrated the real potential of it, as many challenges need to be addressed at different levels: hardware design, software APIs, communication protocols, radio technologies, and so on. In this context, there is a growing interest in reconfigurable devices, as they bridge the gap between performance and energy with the advantage of the hardware flexibility. In this paper, we present a platform with sensor nodes and gateways relying on FPGAs, and showing that reconfigurable devices can be an enabling technology for edge-computing.
