EnerSim: An energy consumption model for large-scale overlay simulators

Determining the energy consumption in large-scale overlay simulations is still an open issue as most existing simulation frameworks are agnostic to that aspect. Especially simulations including mobile devices, such as smartphones or tablet PCs, can benefit from having a energy consumption model in simulations such that newly developed large-scale overlay mechanisms can be evaluated with respect to their energy consumption on mobile devices. Therefore, this paper proposes a component-based energy consumption model, which is based on measurements of existing smartphones. The model causes little computational overhead, thus, being suitable for large-scale simulations. A brief evaluation shows that using our model, the energy consumption can be estimated with a mean error of ±4.7%. Furthermore, the measurements conducted to derive the model show that WiFi and Bluetooth communication are one, respectively two, orders of magnitude more energy efficient than cellular communication.
