Abstract
Aiming at the problem that the Shadowing model commonly used of received signal strength indicator(RSSI) ranging algorithm was limited due to the effect of environmental factors such as the terrain in practice,a RSSI ranging algorithm was proposed based on piecewise polynomial fitting.This method,using of least-squares fitting function,fitted the sampling of a finite number of RSSI data to a continuous piecewise cubic polynomial function,which could simulate more accurately RSSI attenuation under specific circumstances.Using this algorithm and simulation experiments to seek appropriate number of segments and split points, the results showed that the average error was decreased from 2.25 m to 0.877 8 m using two-piecewise fitting method.
