Optimisation de la consommation des noeuds de réseaux de capteurs sans fil

Abstract : Wireless sensor networks pose many design challenges. They must collect information coming from the environment, treat gathered data, receive and forward it with a lifetime that must reach tens of years depending on the applications without any external intervention. It is thus necessary to optimize the energy consumption at every design level. This work proposes to reduce the energy consumption of the digital part of a network node thanks to the use of asynchronous logic and synchronous communications between software and hardware. In addition, it is important to dynamically manage consumption by scaling the supply voltages. This aspect is treated on the whole system, at the material level, thanks to the specification of a dedicated coprocessor, at the algorithmic level and real-time software, and at the communication interfaces between the software and the hardware.
