This paper introduces HiFiNet, a novel hierarchical framework for identifying faults in Wireless Sensor Networks (WSNs). The system uses edge classifiers with LSTM autoencoders for temporal feature extraction and initial fault prediction, followed by a Graph Attention Network (GAT) to aggregate information from neighboring nodes for refined classification. HiFiNet aims to improve accuracy and energy efficiency by capturing both local temporal patterns and network-wide spatial dependencies, outperforming existing methods on synthetic datasets. AI
