EnergyBox is a parametrised tool that enables accurate studies of communication energy at the user end, using real traffic traces as input. Currently it focuses on the most widespread wireless technologies (3G and WiFi) and emulates application data communication energy footprint at the user device. EnergyBox performs trace based iterative packet-driven simulation. The following figure shows an overview of the EnergyBox:
For a given packet trace and input configuration parameters, EnergyBox simulates the underlying states of operation in the wireless interfaces (device states). The configuration parameters relate to the cellular operator network parameters for 3G (e.g., inactivity timers), and the adaptive power saving mode for WiFi specified at driver level.
The tool takes as input the power draw for a given mobile device in the 3G and WiFi transmission states (device power levels), and outputs an estimate of the consumed energy for the given packet trace, either synthetic or captured in a device using real applications.
The versatility and accuracy of EnergyBox was evaluated in a recent paper using nine different applications with different data patterns. A comparison with real power traces indicates that EnergyBox is a valuable tool for repeatable and convenient studies.
EnergyBox is developed as part of the PhD thesis of Ekhiotz Vergara. The current implementation is performed as part of the bachelor thesis of Rihards Polis. Jens Green Olander improved the performance and refactored the code as part of his master thesis at Spotify. EnergyBox has been used to improved the energy-efficiency of several mobile applications (e.g., Spotify).

- Java JDK 8u40 or greater
- tshark (OS X and Linux only)
OS X:
brew install tshark
Linux:
sudo apt-get install tshark
Windows:
- Install WinPcap from https://www.winpcap.org/install/
git clone git@github.com:rtslab/EnergyBox.git
cd EnergyBox
For Windows platforms use the following command: gradle.bat jar
For OS X and Linux use the following command: ./gradlew jar
Optionally, the IDE IntelliJ IDEA comes with good support for gradle projects.
The build in Windows includes the jnetpcap library used to read pcap files. In order to work the jnetpcap.dll needs to be in the same directory as the compiled Jar file.
Make sure the JAVA_HOME environment variable points to the JDK directory.
CLI:
java -jar build/libs/energybox-x.y.jar --t=<trace pcap> --n=<network config> --d=<device config>
GUI:
java -jar build/libs/energybox-x.y.jar
Examples:
java -jar build/libs/energybox-2.0.jar --t=path/to/trace.pcap --n=3g_teliasonera.config --d=nexus_one_3g.config
java -jar build/libs/energybox-2.0.jar --t=path/to/trace.pcap --n=path/to/external/network.config --d=path/to/external/device.config
