Energy Management


Development of strategies for organising energy supply and distribution in heterogeneous, energetically self-sufficient sensor networks with energy consumers, sources and storage devices and realisation of microcontrollers and system-on-chip designs for implementation of these.

Sensors and sensor nodes which work autonomously depend on availability of energy during their periods of activity. Options to ensure a suitable energy supply include energy harvesting and buffer storage of energy. The core of the system, however, must be an adequate energy management system which can guarantee this supply in terms of time and power levels by taking into account all elements involved, from ressources to consumers and their specific characteristics and needs as defined both by the hardware employed and the specific measuring and/or control task. Within the project, basic strategies will be developed which allow context specific electrical energy supply to sensor units as well as sensor and communication nodes. Modelling and simulation of the system is followed by physical realisation based on newly developed microkernels. The implementation phase will initially rely on commercially available microcontrollers. In a second phase, switching to FPGAs is envisaged to lower space and energy requirements of the control unit.
