MATLAB implementation for wireless sensor network node localization using RSSI signal strength measurements and path loss modeling during transmission.
Detailed Documentation
This text presents a MATLAB-based implementation for Wireless Sensor Network (WSN) node localization using Received Signal Strength Indicator (RSSI) measurements during signal transmission with path loss considerations. The algorithm typically involves calculating distance estimates from RSSI values using log-normal shadowing models, then applying trilateration or multilateration techniques to determine node positions. Key implementation aspects include signal propagation modeling, anchor node configuration, and position estimation algorithms. This approach enables accurate determination of individual node positions within wireless sensor networks, facilitating more efficient data transmission and information collection. The MATLAB code would likely involve functions for RSSI-to-distance conversion, coordinate calculation algorithms, and visualization modules to display the localized network topology.
