Research on hidden malicious user detection problem

A method of detecting malicious user based on the enhanced Dempster-Shafer D-S algorithm for the hidden malicious user in cooperative spectrum sensing frame is proposed in this paper. The validity of this method is established by running simulations in the environment of hidden malicious user with different predefined probabilities. Compared with the original enhanced D-S algorithm, the proposed method based on enhanced D-S algorithm in this paper provides a better global sensing performance.
