Review of RSSI-based Positioning Algorithm and Accuracy

Abstract

The demand for high-precision, low-cost, and widely used wireless sensor network positioning technology continues to increase, and the algorithms for positioning using wireless sensor networks have been suffering from the problem of insufficient accuracy. This paper introduces and analyzes the steps and principles of the RSSI algorithm, which has low hardware requirements and can achieve high accuracy positioning, and describes the mathematical model and related algorithms used. Finally, we conclude and provide an outlook on the future and development of RSSI.
