Trilateration Positioning Optimization Algorithm Based on Minimum Generalization Error

Abstract

The positioning accuracy of Wireless Sensor Networks [1] (WSNs) determines the performance of this network. In order to improve the accuracy of mobile node ranging in Wireless Sensor Networks, this paper proposed a Trilateration algorithm based on Minimum Generalization Error. The method using signal strength data of the anchor node which was measured by the RSSI[2] (Received Signal Strength Indicator, RSSI) for modeling, and the Minimum Generalization Error to optimize the Trilateration Positioning algorithm to target node ranging. Compared with the traditional Trilateration positioning algorithm [3]-[4], this method is higher in accuracy and stronger in adaptability.
