| Abstract_FL | In distributed cognitive radio networks,a common fusion center is always not available to collect the users' information.In order to cope with the spectrum sensing data falsification(SSDF) attack lunched by malicious users in the process of spectrum sensing,a spectrum situation fusion algorithm based on comprehensive trust is proposed.The algorithm calculates the instantaneous trust by evaluating the satisfaction of each interaction between secondary users.With consistency test,each node accumulates and updates the long-term trust of every adjacent secondary users.Integrating the instantaneous trust and the long-term trust,the dynamic comprehensive trust is gotten as the main reference for the reliability of interaction data to eliminate the effects of malicious users.Theoretical analysis and simulation results show that the proposed scheme is superior to the traditional cooperative spectrum sensing algorithm on the convergence and stability,and is robust in resisting collusion attack.It can significantly improve the spectrum detection accuracy. |
