| dc.description.abstract | Advertisements are the main source of revenue for many free mobile applications, however, they increase the energy consumption of the mobile device. In particu- lar, the radio communication used for the advertisement data transfer is energy hungry, so advertisement sponsored applications (free) consume more energy than paid applications.In this thesis, we analyse the effect that advertisements have on the mobile device performance, especially, the energy consumption of transferring and displaying advertisements. Our results, based on evaluating 5 mobile games, show that advertisements consume up to ≈25% of application?s total power consumption.To make advertising energy-efficient, we propose and implement a solution (eeAd- Network) that reduces energy consumption by intercepting advertisement re- quests and serving them from a local cache. The proposed solution acts as an extension to the AdMob advertising network. We also run measurements to eval- uate the performance of our proposed solution. Our results show that the power consumption of delivering and displaying advertisements is decreased from 27% to 4% of the application?s total power consumption. | nb_NO |
