SYNTHESIS OF AUTO CALIBRATION SYSTEM IN NON MAINTENANCE WIRELESS SENSOR NETWORK

Abstract

The methods of research and development of calibration of radio sensors with use of various models of parameters drift of radio sensors is solved. The main tasks and approaches to the development and synthesis of the autocalibration system in the network of radio sensors are determined. The proposed method of error detection and correction of measurement results of radio sensors in the network is based on the assumption of spatio-temporal correlation of measurement results in neighboring sensors and the lack of mutual correlation of drift processes of technical parameters. The use of the auxiliary regression vector, according to the equation of which the forecast of future measurement results is calculated, is proposed and substantiated for the analysis of the space-time correlation. It is established that there is a certain compromise in the choice of the optimal sample length during measurements.
