Abstract：Aiming at the problem that traditional collaboration algorithms cannot solve the attack of malicious users,a malicious user(MSU)attack prevention algorithm based on trust degree is proposed.This algorithm establishes a user behavior trust degree model to dynamically evaluate the perception reliability of collaborative users,effectively identifying and filtering malicious data.Simulation results show that in the presence of MSU attacks,the proposed algorithm can effectively reduce the system's missed detection rate and significantly improve the system's perception effect in different channel environments.
