Abstract

In order to understand the water environment quality and improve the production efficiency, a wireless sensor network localization algorithm about water quality monitoring based on RSSI ranging is proposed. Firstly the dynamic path loss index is obtained for ranging, then the measurement range is corrected by the relative error coefficient of the reference node, finally, the weighted least square (WLS) algorithm is used to estimate the node coordinates. By simulation and localization experiments, it shows that this method takes full consideration of the influence of the location error and the number of reference nodes on the positioning accuracy, which can meet the requirements of complex network environment and the location of the monitoring system. Compared with the LS algorithm, the proposed localization algorithm has higher accuracy and lower computational complexity.
