TIDS: Trust Intrusion Detection System Based on Double Cluster Heads for WSNs

摘要

The efficiency and reliability are crucial indexes when a trust system is applied into Wireless Sensor Networks (WSNs). In this paper, an efficient and reliable Trusted Intrusion Detection System (TIDS) with double cluster heads for WSNs is proposed. Firstly, an intrusion detection scheme based on trust is discussed. The monitoring nodes are responsible for evaluating the credibility of Cluster Member (CM) instead of depending on the feedback between CMs, which is suitable for decreasing the energy consumption of WSNs and reducing the influence of malicious nodes. Secondly, a new trust evaluation method is defined in TIDS and it takes the data forwarding and communication tasks into consideration which may enhance the reliability of Cluster Head (CH). The theoretical and simulation results show that our solution can effectively reduce the system overhead and improve the robustness of WSNs.
