| Summary: | This paper introduces collaborative localization algorithms for wireless sensor networks (WSNs) in outdoor environments without GPS. Using a limited number of beacons and anchor nodes, the proposed approach leverages machine learning techniques, specifically Random Forest Regression (RFR) enhanced by Smell Agent Optimization (SAO) and Golden Jackal Optimization Algorithm (GJOA), to optimize network performance and minimize localization errors. The scheme employs up to three beacon nodes to accurately determine ordinary nodes' positions. Evaluation shows that employing three beacon nodes reduces the average localization error (ALE) by up to 40% compared to using two. Moreover, the proposed model, RFGJ, exhibits resilience to increased node density, maintaining accuracy even with higher node densities. The RFGJ model outperforms the other evaluated models, consistently achieving lower ALE values and faster localization times than both the RFSA and RF models. This is evident from the RFGJ model's superior performance metrics during training, including the highest R2 value of 0.996 and the lowest Root Mean Squared Error (RMSE) value of 0.028. These findings establish the RFGJ model as a promising tool for optimizing collaborative localization in WSNs, enabling more efficient and reliable localization across various applications. |
