Energy-aware Sensors Trajectory Tracking (ESTT)
Many location-aware applications often keep track of trajectories of mobile device over a long period of time. The naive way: get GPS coordinates every certain time interval and then connect the these points to get the trajectory. However, the energy consumption of GPS is well-known high.
SETT Tracks the trajectory by use various sensors on mobile device instead of only utilizing the GPS component. Then use Markov Chain to infer the trajectory based on the data from sensors. Below are the sensors used in SETT.
