Abstract- This paper presents an in-depth study on a navigation
application that has cloud-based and non-cloud-based versions
running on the Android platform. We discovered that the c1oudbased
Osmand is more energy inefficient than the non-c1oudbased
Osmand. This is because the tail energy in 3G
communications causes extra energy consumption for c1oudbased
Osmand. Thus, we have designed an Energy Efficient
Scheduling Manager (EESManager), which benefits from its
awareness of both tail energy and the complexity of the map. As
the evaluation results show, cloud-based Osmand with
EESManager can reduce overall energy consumption in case of a
simple map between the source and destination points
