Machine learning based dynamic trust estimation framework for Securing wireless sensor networks
The proposed SMART model enhances Wireless Sensor Network (WSN) security by dynamically generating trust values using machine learning (ML) algorithms. It integrates novel features like Co-Location Relationship (CLR), Co-Work Relationship (CWR), and Cooperativeness-Frequency-Duration (CFD) to proactively detect misbehavior. Utilizing K-means clustering, Principal Component Analysis (PCA), and Support Vector Machine (SVM), SMART achieves 96% accuracy and 0.7% False Negative Rate (FNR) in detecting malicious nodes, significantly improving network trustworthiness and integrity.

Introduction to WSN Security
Wireless Sensor Networks (WSNs) face inherent vulnerabilities to diverse attacks, including data tampering, node compromise, and insider threats, which compromise data integrity and network functionality. Traditional security protocols are often insufficient to adapt dynamically to these evolving threats. Trust-aware Machine Learning (ML) frameworks offer a robust solution by actively monitoring trust levels, enhancing the detection of malicious behavior, and strengthening overall network security and integrity.
SMART Model Core Features
The Secure Machine-learning-based Adaptive Reliable Trust (SMART) model introduces novel trust features: Co-Location Relationship (CLR) for spatial proximity, Co-Work Relationship (CWR) for collaborative interaction, and Cooperativeness-Frequency-Duration (CFD) for long-term reliability. These dynamic metrics collectively provide a comprehensive assessment of sensor node trustworthiness, allowing the system to predict potential misbehavior and make informed decisions on device reliability in unattended, autonomous WSN environments.
ML Algorithms Used
SMART leverages a suite of powerful ML algorithms for efficient data processing and decision-making. K-means clustering is employed to assign data points to nearest K-centers, optimizing cluster identification. Principal Component Analysis (PCA) is utilized for significant variance identification and dimensionality reduction, enhancing performance and accuracy. Finally, a Support Vector Machine (SVM)-based method is used for accurate decision-making and classification of sensor nodes with lower time and space complexity.
Performance Evaluation
The SMART framework's performance is rigorously evaluated using measures such as accuracy, F1-score, recall, false negative rate (FNR), malicious SD detection rate, and trust value change. Simulation results demonstrate its effectiveness, showing a 96% detection rate for malicious nodes, a 0.7% FNR, and an F1-Score of 0.75, even with up to 50 malicious nodes present. This confirms SMART's ability to significantly enhance the trustworthiness and security of WSNs.
Comparison with Existing Methods
SMART outperforms conventional trust models by integrating dynamic trust measures, advanced hybrid ML techniques (K-means, PCA, SVM), and an adaptive reward and punishment system. Unlike static or single-algorithm approaches, SMART's holistic evaluation, incorporating spatial, collaborative, and temporal trust metrics, allows for more precise anomaly detection and greater resilience against evolving threats, leading to superior accuracy and reduced false negatives.
