In wireless sensor networks (WSNs), due to fault and malicious behaviors of network entities, the collected sensor data might not be accurate. Therefore, it is crucial to effectively detect and isolate malicious network entities from the network. Some studies have been demonstrated that rating trust and reputation of individual network entities is an effective approach in WSNs to improve security, support decision-making process and promote collaboration between network entities. However, trust management systems are prone to attacks from inside of the network. Insider attacks like selective forwarding and bad-mouthing can significantly deteriorate the trust management systems and results inaccurate trust evaluation of network entities. In this work, based on wireless overhearing mechanism we propose a novel approach which can effectively detect and isolate malicious network entities in WSNs. Simulation studies shows that, compare to other similar schemes, the proposed CMBNI scheme can detect and isolate malicious entities with high accuracy and speed.
