Abstract:
Today’s smartphones are equipped with numerous different sensors and are capable of providing a large number of diverse services. But due to the high energy consumption of built-in sensors, as well as because of the energy consumed while analyzing gathered raw data, a bottleneck in resource supply is likely to occur during a service provision. This bottleneck leads to one of the biggest challenges regarding the developments on mobile devices: the trade-off between a high shortterm service performance and sustainable energy management. Furthermore, despite of numerous hardware improvements (e.g., energy saving displays, batteries with bigger capacities, etc.) this issue remains unsolved. Hence, software-based approaches can be used to optimize the resource and energy management on mobile devices according to the user’s preferences, existing context information, and the current energetic state of a device. Moreover, a holistic energy management enables the system to provide context dependent services. In this article, we present a concept for custom tailored service provision on mobile devices in combination with EMMA (Energy Management Middleware Architecture), a modular architechture for managing a mobile device’s service infrastructure in relation to its current resource state as well as to the user’s individual preferences. Additionally, we give an insight into our prototypical application, which demonstrates EMMA’s core concepts including its featured approach of individual service provision.
