Abstract
Las nuevas funcionalidades y la integración de diferentes tecnologías de comunicación en los nuevos dispositivos móviles hacen que el consumo de potencia se dispare, en unos dispositivos que disponen de una fuente de energía muy limitada. Como consecuencia, ha aumentado la preocupación sobre cómo administrar y ahorrar energía. Entender y caracterizar el consumo de energía en un dispositivo móvil es necesario para poder desarrollar métodos de administración de energía que permitan reducir el consumo. Con este objetivo, el presente proyecto fin de carrera lleva a cabo un estudio sobre el consumo de energía en un dispositivo con sistema operativo Android. Android, creado por Google y de código abierto, es uno de los sistemas operativos para dispositivos móviles con mayor penetración en el mercado. Además de ofrecer gran funcionalidad y un potente entorno de desarrollo, Android implementa un mecanismo de administración de energía con el objetivo de reducir el consumo cuando el dispositivo no está siendo utilizado. Se ha desarrollado una metodología que permite obtener el consumo de distintos componentes hardware del dispositivo bajo estudio. Los resultados experimentales obtenidos permiten definir qué componentes son los que descargan a mayor velocidad la batería y consumen niveles de potencia más altos. Ya que la mayor parte de la potencia consumida se atribuye a las tecnologías de comunicación, se lleva a cabo un análisis más detallado sobre el consumo de las tecnologías Wi-Fi y 3G. ____________________________________________________________________________________________________________________________
The new functionalities and the integration of different communication technologies increase drastically the power consumption in new mobile devices, which are powered with a limited source of energy. As a result, the awareness about how to manage and save energy has increased. Understanding and profiling the energy consumption in a mobile device is necessary to develop new methods for energy management in order to reduce power consumption. To this end, this final degree project carries out a study about the energy consumption in a device with Android operating system. Android, developed by Google, is one of the operating systems for mobile devices with a higher market penetration. As well as providing a large functionality and a powerful development environment, Android implements an energy management mechanism which has the goal of reducing power consumption when the device is not being used. We have developed a methodology to obtain the power consumption by different device hardware components. The experimental results show which components drain the battery faster and consume high power levels. Since the main part of the power consumption is attributed to communication technologies, we have carried out a more detailed analysis about energy consumption of Wi-Fi and 3G technologies.
