An identification method of malicious nodes in wireless communication based on dynamic reputation algorithm

Due to the complex internal structure of wireless communication network, the traditional methods for malicious node identification are relatively single, which leads to a large number of security risks in the network environment. This paper proposes a method of identifying malicious nodes in wireless communication based on dynamic reputation algorithm. A model of WSN wireless communication malicious node identification based on routing protocol reputation mechanism is established. The network is divided into clusters to determine the transmission path of network packets. Send the packet to the sink node and analyse it, calculate the node number and reputation value in the packet and compare with the threshold value to realise the identification of malicious nodes in wireless communication. The simulation results show that the proposed method can complete the identification of malicious nodes in wireless communication with high accuracy, and it takes less time and has better recognition performance.
