Abstract

Objectives: In order to provide efficient knowledge for location aware computing system in mobile applications, this paper proposes an experimental analysis considering user’s location information. Methods/Analysis: These systems can entail information from array of sensors. Context aware management system combining central, distributed management scheme along with sensors, which can be utilized for location application. In order to provide better context/ location aware management system, sensors (magnetometers) are mounted on Gimbal platform. This sensor platform synchronizes the device direction in all three axes.
Findings: Magnetometer sensor can detect ground changes with respect to orientation angle with maximum accuracy. These possessions are validated with magnetic field intensity & rotation headings towards the north direction. Calibration of magnetometer reduces the noise and drift variations in the output.
Conclusion :The proposed analysis offers displacement of the device and ensures the quality of service.
