Abstract EN
This paper presents an extended Kalman filter-based hybrid indoor position estimation technique which is based on integration of fingerprinting and trilateration approach.
In this paper, Euclidian distance formula is used for the first time instead of radio propagation model to convert the received signal to distance estimates.
This technique combines the features of fingerprinting and trilateration approach in a more simple and robust way.
The proposed hybrid technique works in two stages.
In the first stage, it uses an online phase of fingerprinting and calculates nearest neighbors (NN) of the target node, while in the second stage it uses trilateration approach to estimate the coordinate without the use of radio propagation model.
The distance between calculated NN and detective access points (AP) is estimated using Euclidian distance formula.
Thus, distance between NN and APs provides radii for trilateration approach.
Therefore, the position estimation accuracy compared to the lateration approach is better.
Kalman filter is used to further enhance the accuracy of the estimated position.
Simulation and experimental results validate the performance of proposed hybrid technique and improve the accuracy up to 53.64% and 25.58% compared to lateration and fingerprinting approaches, respectively.
