Abstract

Mobile consumer-electronics devices, especially phones, are powered from batteries which are limited in size and therefore capacity. This implies that managing energy well is paramount in such devices. 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, namely, Bluetooth, WiFi and 3G . We proposed an energy and time consumption model that is based on these measurements. Using proposed model one can not only calculate energy consumption for each communication technology, but can also save energy while simultaneously using WIFI, Bluetooth and 3G at the same time. This paper shows how our energy consumption model can be used on an example of the service called Collaborative Consumption of Energy (CCE). The primary goal of CCE 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; as well as, when all of the above components are in play, which one hibernates or kept inactive and which one remains active.
