This paper presents implementation of RSSI (Received Signal Strength Indicator) based localization algorithm using narrow bandwidth radio signal for indoor application. System set up involves into three phase, (1) System Calibration (2) Parameter Optimization and Noise Estimation (3) Performing Localization and Run Time Sensor Network Extension. The system consists of a nodes’ collection (Sensors and Master) which are in together establish a network to perform the localization task in a different indoor environments. RSSI is measured between the sensor and master nodes in a known distance and these two parameters are used to calibrate the radio propagation parameter. An error is calculated at each calibration phase and later it uses to define the environment noise mainly slow fading issue. Moreover, though in the experiments it is observed that RSSI using narrow bandwidth is more sustainable than the wide bandwidth signal, noise elimination filter is used before the system take into account of a sample RSSI at known distance or at run time. Therefore instead of single sample, this system prefer to use a set of samples signal about 10 ms time gap. The experimental results showed that the system and methodology which has been implemented, can improve the localization accuracy in the indoor environment and also perform the dynamic Wireless Sensor Network (WSN) Extension at run time.
