“…Consequently, this results in low accuracy of the positioning coordinates. The system is designed by adding an inertial system to improve the positioning accuracy of the ZigBee IPS [9]. The inertial system is used to suppress the random jitter of the RSSI.…”

“…From the data and information obtained regarding the access point and moving terminal, the coordinates of the person/object can be calculated accurately if the step size of the person is known. However, the step size of the person is changing within a specific range, and the Kalman filter is used to follow the change of step size effectively and continuously adjust the Kalman gain to reduce the interference of this noise [9].…”

Indoor Positioning System (IPS) has been widely used in today’s industry for the various purposes of locating people or objects such as inspection, navigation, and security. Many research works have been done to develop the system by using wireless technology such as Bluetooth and Wi-Fi. The techniques that can give some better performances in terms of accuracy have been investigated and developed. In this paper, ZigBee IEEE 802.15.4 wireless communication protocols are used to implement an indoor localization application system. The research is focusing more on analyzing the behaviour of Received Signal Strength Indicator (RSSI) reading under several conditions and locations by applying the Trilateration algorithm for localizing. The conditions are increasing the number of transmitters, experimented in the non-wireless connection room and wireless connection room by comparing the variation of RSSI values. Analysis of the result shows that the accuracy of the system was improved as the number of transmitters was increased.
