Abstract

With the rapid development of information technology today, the need for location determination services continues to increase. Global Positioning System (GPS) has become the most widely used service in everyday life. However, GPS services are not very good at determining indoor locations. Wifi-based location determination using the RSS technique has proven to be better at determining indoor locations. In this study, the trilateration and Kalman filter methods were tested to determine the indoor location. A total of 100 RSSI data are retrieved in a building with dimensions of 8x8m with three transmitters or access points. There are three test scenarios. In scenario one, using the trilateration algorithm without the Kalman filter, the MSE accuracy is quite good, namely 0,68 m and a standard deviation of 0,31. In scenario two, using the trilateration algorithm and Kalman filter to process RSSI data, the MSE accuracy is slightly better, namely 0,56 m and a standard deviation of 0,14. In the third scenario using the trilateration algorithm and the Kalman filter to process the distance data from the RSSI conversion to the distance value, the MSE accuracy is quite good, namely 0,62 m and a standard deviation of 0,22. From the results of this study, the trilateration algorithm has success at determining indoor locations and the Kalman filter algorithm was able to stabilize data and improved the accuracy.
