Algorithmic optimizations for energy-efficient monitoring of spatial objects on smartphones

Abstract

Location-based services are about to take the next step to proactive services which need continuous positioning for monitoring spatial objects. But so far that also results in severe battery drain in mobile devices due to deficient positioning APIs and the absence of energy-efficient positioning with several positioning methods. By using a hierarchical positioning concept this work provides a general algorithmic optimization to extend existing positioning APIs for energy-efficient positioning without diminishing accuracy. First prototypic implementations on Android handsets show a promising decrease in energy consumption.
