W. Narzt: Context-Based Energy Saving Strategies for Continuous Determination of Position on iOS Devices , Proceedings of the 47th Hawaii International IEEE Conference on System Sciences (HICSS 2014), Big Island, Hawaii, USA, January 6-9, 2014. doi:10.1109/HICSS.2014.125
Continuous determination of position on modern smartphones, in particular permanent utilization of GPS, considerably reduces operating times of batteries. However, incessant exploitation of power for determining the current location is avoidable, e.g., while the device is not being moved. This basic idea of considering the kinetic context of a device for localization enables the development of advanced localization techniques positively impacting energy consumption. This paper outlines the fundamental concept and the architecture for context-based energy saving strategies for continuous location determination on mobile devices, practically implemented on iOS. It proves their potentials in terms of energy consumption by a series of conducted tests, reflects on accuracy issues, and discusses reutilization for other platforms.
