| Abstract: |
| To enhance the security of wireless sensor network and address data anomalies and packet loss caused by network attacks during clustering routing,a node trust management-integrated attack detection algorithm is proposed.The framework establishes a trust management model that calculates node trust values based on communication parameters,classifies nodes into trust levels through adaptive classification thresholds,and analyzes attack-specific communication patterns to extract relevant parameters.Suspicious nodes flagged by the trust model undergo targeted detection,enabling rapid identification and removal of malicious nodes.A secure routing data transmission algorithm is subsequently formulated by integrating trust management with real-time attack detection.Simulation results demonstrate the ゛lgorithm搒 effectiveness in isolating compromised nodes and improving data transmission reliability.Under extreme network threats,the proposed scheme achieves an 11% increase in packet delivery rate compared with baseline methods. |
