Abstract EN
The range measurement is the premise for location, and the precise range measurement is the assurance of accurate location.
Hence, it is essential to know the accurate internode distance.
It is noted that the path loss model plays an important role in improving the quality and reliability of ranging accuracy.
Therefore, it is necessary to investigate the path loss model in actual propagation environment.
Through the analysis of experiments performed at the wheat field, we find that the best fitted parametric exponential decay model (OFPEDM) can achieve a higher distance estimation accuracy and adaptability to environment variations in comparison to the traditional path loss models.
Based on the proposed OFPEDM, we perform the RSSI-based location experiments in wheat field.
Through simulating the location characteristics in MATLAB, we find that for all the unknown nodes, the location errors range from 0.0004 m to 5.1739 m.
The location error in this RSSI-based location algorithm is acceptable in the wide areas such as wheat field.
The findings in this research may provide reference for location estimation in large-scale farmland.
