Energy consumption in android phones when using wireless communication technologies

Wireless communication technologies enable communication among different devices that are within a certain radius. Although, this radius is definite, communication when using wireless communication technologies is more flexible than when using wireline approach. This paper presents results from a measurement study where we measured energy consumption of three wireless communication technologies: Bluetooth, WiFi and 3G. We proposed an energy consumption model that is based on these measurements. Using proposed model one can calculate energy consumption for each communication technology. We show how our energy consumption model can be used on an example of the service called Collaborative Downloading. The primary goal of Collaborative Downloading service is to lower the overall energy consumption of mobile users while downloading data combining together 3G and Bluetooth or 3G and WiFi communication technologies.
