A Node Localization Method Using RSSI Algorithm

Resource Overview

This method implements node-to-node localization utilizing the RSSI algorithm for distance estimation and position calculation.

Detailed Documentation

This article presents a localization approach between nodes using the RSSI (Received Signal Strength Indicator) algorithm. The method operates by measuring signal strength between nodes and converting RSSI values into distance estimates through path loss models. Based on these distance calculations, node positions can be determined using triangulation or polygon localization techniques. The implementation typically involves signal strength sampling, noise filtering algorithms like moving average filters, and distance conversion using logarithmic path loss models. Key advantages include simplicity and cost-effectiveness, as the method requires no specialized hardware or software support - leveraging standard wireless communication modules commonly available in IoT devices. The algorithm can be implemented using basic trigonometric functions for position calculation and signal processing libraries for RSSI data calibration.
