An Energy-Efficient Localization Strategy for Smartphones
In recent years, smartphones have become prevalent. Much attention is being
paid to developing and making use of mobile applications that require position
information. The Global Positioning System (GPS) is a very popular localization
technique used by these applications because of its high accuracy. However, GPS
incurs an unacceptable energy consumption, which severely limits the use of
smartphones and reduces the battery lifetime. Then an urgent requirement for
these applications is a localization strategy that not only provides enough
accurate position information to meet users' need but also consumes less
energy. In this paper, we present an energy-efficient localization strategy for
smartphone applications. On one hand, it can dynamically estimate the next
localization time point to avoid unnecessary localization operations. On the
other hand, it can also automatically select the energy-optimal localization
method. We evaluate the strategy through a series of simulations. Experimental
results show that it can significantly reduce the localization energy
consumption of smartphones while ensuring a good satisfaction degree
