Estudio del consumo energético de dispositivos móviles en redes oportunísticas

Abstract

[EN] The duration of batteries is a key factor that must be considered in the design and deployment of applications and services for mobile devices. The users of this technology are not aware of the energetic impact of the applications executing in their devices, especially if these applications present an adaptive behavior. The goal of this paper is to study the power consumption associated to an oppor- tunistic communications application. This will be achieved by analyzing the di erent operation stages of an application running on mobile and vehicular devices, using basic statistical analysis calculations on the data collected by a logging application. Furthermore, this will allow analysing the impact of this kind of applications regar- ding battery performance, providing useful information to users and developers. The experiments were executed in an opportunistic network environment, using a oating content approach as a mechanism for information distribution in a geo- graphically delimited zone. Based on the results, our evaluation showed that the power consumption in an opportunistic network is moderately low, making feasible and recommendable the deployment of applications of this communications environment. Furthermore, we conclude that, in opportunistic networking, the impact on mobile device batteries is greater since the application must be running permanently. An approach to reduce the battery consumption is to have the app running only when it is in an anchor zone . Also, we can state that, when a mobile device stays in the anchor zone , the power consumption is greater than when it is sending information. This is a consequen- ce of the periodical swapping of protocol control information, a procedure required to receive and retransmit the packets in an anchor zone . Under these circumstan- ces, the correct and adequate tuning of this process is crucial to minimize power consumption [ES] El objetivo de este trabajo es presentar una medición del consumo de poder de un esquema de comunicación oportunístico, en base a estados de comunicación y funcionamiento de lo

[ES] El objetivo de este trabajo es presentar una medición del consumo de poder de un esquema de comunicación oportunístico, en base a estados de comunicación y funcionamiento de los dispositivos móviles, utilizando para su análisis cálculos estadísticos básicos sobre información recolectada por una aplicación desarrollada para este efecto. Permitiendo calcular valores de consumo poder y tiempo de duración de la batería de un dispositivo móvil. Las pruebas se llevarán a cabo utilizando aplicaciones de redes oportunísticas bajo el esquema de Floating Content.
