A study of indoor positioning by using trigonometric and weight centroid localization techniques
An indoor positioning system was developed to provide a fast and easy determination of unknown position coordinates. Wireless sensor nodes (WSN) are employed in a test area. Trigonometry techniques were employed to determine the position of the unknown objects by employing numerical analysis techniques on received signal link quality indicator (LQI) values. The distances between the unknown object position and the WSNs...
