Extended Gradient Predictor and Filter for smoothing RSSI

Abstract: Abstract-This paper presents the design of an Extended Gradient Predictor and Filter for smoothing Received Signal Strength Indicator (RSSI). In wireless communication RSSI is a measurement of power in received signal, which is a parameter used for handover and position estimation purpose. In real time applications such as handover and position estimation requires continuous reception of RSSI measurements. Due to the effect of noise, variations occur in the received signal, which sometimes produce communicatio… Show more

“…Therefore, in practical applications, the use of preprocessing techniques on raw collected data helps the RSSI to be a suitable estimator of distance [ 26 ]. Rough localization is performed using RSSI, which is the parameter used to estimate distance between mobile and anchor nodes or APs [ 27 ]. The position information of the robot and the MAC address and RSSI of different APs are recorded at the recording positions.…”

“…The effectiveness of the proposed extended Gradient RSSI predictor and filter is presented by comparing it with the original Gradient filter using ideal and simulated RSSI measurements [14]. Ideal RSSI measurements reflect the real-time RSSI measurements obtained with respect to time, while simulated RSSI measurements reflect the presence of communication holes.…”

“…In [11], the authors conducted a survey regarding localization techniques, mentioned that GPS and cellular networks are outdoor localization sources, and they failed to localize anything indoor because of the deep shadowing effect. In [12], Subhan et al proposed an extended gradient predictor and filter to reduce variation in RSSI values. e RSSI values get variation due to various factors such as walls, obstacles, human crowd, and temperature.…”
