[Abstract]:Accurate detection of wireless network transmission data node intrusion can ensure the safe operation of wireless network. When the intrusion detection is carried out, the node behavior should be quantified and compared with the reputation value of the network node by using the pre-set reputation threshold to complete the detection. However, the traditional method analyzes the spontaneous critical state of variables in a certain area of wireless network, and finds out the most vulnerable network nodes to complete intrusion detection. However, it is impossible to compare the creditworthiness threshold of the node to be detected with the reputation value of the normal network node, which reduces the accuracy of intrusion detection. A wireless network transmission data node intrusion detection method based on reputation mechanism is proposed. Firstly, the behavior attributes of wireless network nodes are analyzed. After quantizing the data such as packet loss rate and transfer rate of nodes, a model is built to analyze the different attributes of different nodes. Then, the different attribute nodes are analyzed and judged by the established reputation mechanism, then the behavior of the nodes is quantified and compared with the reputation value of the network node by the pre-set reputation threshold. The relationship between the reputation value of the detected node and the pre-set threshold is determined, and whether the node is abnormal or not is detected. The simulation results show that compared with the traditional threshold method of reputation mechanism, the improved method can effectively detect the node intrusion status and provide support for the safe use of network data.
