Abstract

With the growing popularity of the application of wireless sensor network, the demand to the accuracy of wireless network is increasingly strict, the traditional location algorithm has been difficult to fulfill the needs of practicable applications. This paper proposes a new RSSI positioning algorithm based on the triangle positioning algorithm in accordance with the character of received signal strength and by modifying the proportion between path length and path loss to improve the ranging accuracy, and then uses the triangle centroid algorithm to estimate the coordinate position. Though simulation experiment, it turned out that the accuracy of algorithm has improved compared with triangle centroid positioning algorithm on the basis of RSSI.
