| Abstract | Abstract—In mobile applications, like wireless sensor networks, it is often inevitable to use a location-independent source of energy. Wherever the batteries capacity or inefficient energy harvesting limits the lifetime, other solutions have to be implemented to increase the energy efficiency. Dynamic Voltage Scaling (DVS) is a well known technique with the ability to adapt the voltage level to the actual system load to save energy. While it has been used in many application areas, DVS has not been studied sufficiently for wireless sensor nodes. In this demo, we show the benefits of DVS. We were able to optimize DVS for an 8-Bit ULP micro controller by a combination of DVS and dynamic power management (DPM). Moreover, we analyzed the effect of voltage scaling on other components of the sensor node (transceiver, sensors and memory). Index Terms—wireless sensor node, energy efficiency, voltage scaling, hardware architecture, hardware design, dvs. I. |
