Abstract:
Smart phones are increasingly becoming powerful sensor devices which can be used to continuously sense the user's environment such as the location coordinates. Numerous smartphone applications such as augmented reality and navigation requires accurate stream of location data. One of the major challenges in location sensing is energy efficiency. GPS is the primary source of location information and the continuous use of GPS has a major impact on the device's battery life. In this paper we describe an energy efficient framework which can provide a continuous stream of location data to the applications. We describe an adaptive duty-cycling strategy combined with a location estimation mechanism. We show that our location estimator provides reasonable accuracy while providing high energy efficiency.
