Demo Abstract: PRINCE: Device Energy Estimation with a Single Photo

We contribute PRINCE, an innovative sensing solution capable of accurately estimating the energy consumption of applications executing on a wider range of smart and IoT devices, including smartwatches, wearables and autonomous drones, without the need for direct instrumentation of the device. Modern devices lack detachable batteries or are sealed, making it challenging to profile their energy consumption. In this demo, we showcase PRINCE, a proof-of-concept prototype that provides precise energy consumption measurements of applications running in devices with a single (thermal) photo. PRINCE harnesses the thermal radiation (heat) generated by the processing units of the device, which is released through the device casing. This allows PRINCE to derive accurate energy estimations of application execution. Extensive benchmarks that compare PRINCE with traditional solutions, such as Monsoon power monitor, demonstrate that PRINCE provide similar performance levels but does not require any instrumentation, facilitating the profiling of the energy consumption of devices.
